Original subtitles

Tonight on the Curse of Oak Island.

Isn't that a Templar cross?

This cross is Portuguese.

I do have evidence that puts them at this location from 1500 to 1580.

We want to get to the bottom of 10X. Going down. How you making out?

I'm having a hard time with this. This is not a routine dive.

I'll stop.

Drop the bucket. Slow.

That looks like something.

Stop! There's a wall here.

There is an island in the North Atlantic where people have been looking for an

incredible treasure for more than 200 years.

So far, they have found bits of gold chain, a stone slab with strange symbols

carved into it, even a 17th century Spanish coin.

To date, six men have died trying to solve the mystery.

And, according to legend,

One more will have to die before the treasure can be found.

looks like it's right here there's a beam is that a wall that could

be the wall yeah yep i think we found it brothers rick and marty lagina

may be on the verge of one of the most important breakthroughs in the 220 year

old oak island mystery while digging in the area where the original money pit

was discovered in 1795 they have just uncovered a section of wall they believe

is part of a 78-year-old searcher tunnel called the Hedden Shaft.

Constructed in 1937 by treasure hunter Gilbert Hedden, the 12 by 24 foot shaft

went 125 feet deep underground and was believed to have intersected the

original money pit.

Finding the Hedden Shaft could be the key to determining the exact location of

the long-lost treasure site.

When Gilbert hadn't dug that shaft, he thought he was digging in the money pit,

and he was that much closer to history than we are.

So we thought that by locating that accurately, digging down and finding the

corners, it's another clue to pin down the money pit.

So what that tells you is it's going to take a lot of bulwark.

Drop the bucket right here. I'm standing right here. I'm gonna put it right on it

and then you just pull right there Okay, but I have to stand here. All right,

just move back a bit, please I'm like a surgeon with this thing Surgeon was

a bit of a stretch. Yes surgeon, but I still trusted you He's put that with us

your head down. I'll flip it right on your head for you. I Trust you in a lot

of ways, but not that

I was comfortable being in the hole when he was operating. I knew, look, we had

the same goal, and I never worried, not even one single time.

I don't like swinging this over your head.

Slow.

Rick was perfectly calm.

He trusts me to not hit him with that bucket.

Forget hit. If you just touch somebody with that thing, that probably weighs

four tons or something.

So I was trying to be very careful.

Dan, come around.

You think that is the wall, Dan?

Yeah, that looks like Goodwall down below there. Come down and take a look

for yourself.

You know, I was hoping you'd say anything but that.

Finding a section of a wooden wall offers proof that Rick, Marty, and Dan

have found the hidden shaft that rick is amazing i know that is solid we

have found it that is clearly the exterior wall of the old head and shaft

uncovering the head and shaft is a major discovery finding it will

now allow rick and marty to pinpoint the exact location of the original money pit

it's a lot different than we thought we thought it went off that way but first

They will need to determine which wall of the hidden shaft they've found and

where its corners lie.

We at least have a bearing.

We don't have a distance yet because we're not sure of the corner.

So when we find that corner, keep digging, right?

I was astounded because we're going to know better than anyone on earth where

the original money pit was.

Well, that's a big deal.

Rick, I'm wondering if it's right under this stuff, right under your foot.

I think it's right under here.

Well, actually, it could be.

That's a piece of wood. You're splintering it.

There's nothing below it.

It seems to be at the right angle at the right distance to be the other wall.

Yeah, but there should be something below it. You know what, Rick?

That piece looks like it pulled right out of there. Look at that.

That's the piece that pulled out of there.

That's the corner.

Look at that, Rick. It was buried right in there at a perfect right angle.

Rick, that's the corner for sure.

We found the corners of the head and shaft, thus we can orient off them, and

thus we know roughly where the money pit should be.

Well, look.

We have one wall firmly established.

We have the orientation firmly established.

we've learned something because we thought it went that way and it really

goes that way after digging for the better part of a day rick marty and

their partners have excavated approximately half of the 24 by 12 foot

head and shaft as a team i think we did some nice work and we have accurately

located the head and shaft that is an accomplishment okay let's call it a day

let's declare victory partial victory for tonight

Crown time.

Yeah.

After a successful day of searching, Rick, Marty, Dave Blankenship, Craig

Tester, and his stepson, Jack Begley, gathered to celebrate at a nearby pub.

So it wasn't a bad day today because I think I performed admirably on that

excavator. What do you think?

He didn't kill me.

Well, are we going to keep digging?

No.

Why not?

I think there are several reasons, Jack. I mean, first of all, our intent was to

just locate it so that we could then use it to locate the money pit, okay?

That would be one. Two, this is dangerous, damn dangerous.

We don't know how it was filled. The soils are so unconsolidated.

I mean, it could be bridged.

There could be 50 feet of open hole down there. Just sand is bridged above it.

I mean, I was a little bit on pins and needles the whole time he's in there,

waiting for him to kind of disappear, you know, whoosh.

And then we have the limit of the equipment we have there, too. You know,

it's a 22-foot boom.

We'd have to bring in different equipment.

Marty's decision to stop digging at the money pit is a strategic one.

Rather than face flooding or a dangerous cave-in, he and his brother have decided

to wait until they can get scanning sonar into the hole that Craig Tester

drilled last summer.

The same hole where they found evidence of a large wooden vault that was first

discovered by treasure hunter Frederick Blair and drill operator William

Chappell back in 1897.

Definitely got wood.

That's definitely cement.

Concrete and then wood.

That's the description.

That's what they found in the top of the vault.

What we're really after is verifying what Craig found with borehole Valley 3,

whether that's in the money pit or not. And I would say, you know, I'll quote

the eight ball, signs point to yes, because that head and shaft, at least

according to the roper survey, would indicate that you drilled right on the

edge of the money pit, which is exactly what the bit said, right?

So we're pretty hopeful. It's showing that the vault Craig hit is probably the

vault. I think that's a fair statement, yeah.

Can't beat that.

Oh, is that the depth? And now we know it's the same location. It's in the

right spot, yeah.

Well, we had a good day, gentlemen.

Got the head and shaft. That'll help us in our exploration in the money pit.

So it was a good day. We call it a success.

Go home.

It'll be neat to actually see the Overton Stone.

We're going to make it reveal its secrets.

Well, I think it's a far fetch, but we'll see what happens.

One day after locating both the head and shaft and the money pit, brothers Rick

and Marty Lagina, their partner Craig Tester, and veteran treasure hunter Dave

Brankenship are traveling to the small seaside town of Overton, Nova Scotia.

There, they plan to meet with local historian, terry duvall and investigate

the stone carving that oak island researcher robert marcus believes was

pointed to in an antique treasure map this is the starting point okay this is

called the boat stone a stone that was found in westford massachusetts the boat

represents a coastal range follow the coast the number 184

the unit of measure back then was called a league

Now, 184 leagues north takes you to Overton, Nova Scotia.

When you get to there, you find the stone.

Within the stone right here, you have a depiction of the circle with the

Templar's Cross in it.

Now, David, if he connects your Templars with Oak Island, you'd be quite pleased

by that, right?

Yep.

Open mind, that's all.

I'm here, aren't I?

Yes, you are.

Is this the guy we're supposed to meet?

Let's go say hello.

Hello. Terry. Terry Duvaux. Rick. Nice to meet you.

Terry Duvaux is a historian and researcher who has studied petroglyphs,

rock carvings, and stone structures.

throughout Canada and the United States.

He is also president of the New England Antiquities Research Association.

So is it this way? Pretty much. OK. OK. Let's go. Let's go.

Terry DeVoe's research has led him to make an incredible connection between

Nova Scotia's early history and Oak Island, a connection that could offer a

key piece of information in solving a centuries-old mystery.

The rock here is probably located on the highest point in quite a distance

around.

So now you can see the carving quite clearly here. It's very beautiful.

It has four main elements, a cross that's in a circle,

an eagle feather,

These two things behind the eagle feather that I interpret as tobacco

leaves and a moon, crescent moon.

That is quite remarkable.

And isn't that a Templar cross?

A Templar cross?

Could the carving Terry Duveau has brought the team out to see really be

hundreds of years old?

We'll talk about that in a few minutes.

But what I want to highlight is the fact...

that there is a controversy as to whether or not this is an old carving or

a recent carving. Right. That's always the issue. That's always the issue. And

the problem with saying that this is an old carving is that it looks fairly

fresh. But that could be deceptive in this case because this is a type of rock

geologically

that appears to weather very slowly because it was formed by volcanic ash

that fell in layers and then got compacted and under the effect of

pressure over time formed this type of rock. And the patina, which is the outer

crust of the weathering, is fairly thick right here, but has probably taken 15

,000 years to develop.

Okay, so if you had to say most likely...

this old and most likely this sort of thing, what would your answer be?

Well, I think it's clear that the carving is a genuine historical artifact

and quite old, possibly up to 500 years old.

500 years old?

Could this stone carving really date as far back as the 1500s? What about the

circle and the four dots?

Does that have any special meaning to it?

That is something I would like to pursue.

So you have the cross with the circle that obviously is a Christian symbol.

Right. The eagle feather, and behind the eagle feather, there are a pair of

tobacco leaves.

There you have two of the most important symbols in the Mi'kmaq belief

system.

The hypothesis that I'm suggesting is that this whole carving was made by a

European. to commemorate, perhaps, a friendship treaty between Europeans and

Mi'kmaq.

So the question becomes, which European group would be represented by this

cross?

As the first known inhabitants of North America's northeastern region, the Mi

'kmaq people had their earliest recorded contact with Europeans as far back as

the 15th century.

but there are many in the mi'kmaq community who believe that that contact

stretches back even earlier back as far as the thirteen hundreds and the days of

a scottish templar knight by the name of henry sinclair could the overton

carvings be even older than terry devoe believes possibly dating as far back as

the fourteenth century

You know, we're up to our eyeballs in all these various hypotheses.

Right. And what you just said, if the timing were right, would apply to this

legendary Henry Sinclair voyage perfectly.

According to legend, in 1398, Prince Henry Sinclair sailed across the North

Atlantic from Scotland to Oak Island, nearly 100 years before Columbus.

There... he is said to have buried a number of sacred religious treasures

that had been rescued from the holy land during the crusades among the items were

the golden menorah of king solomon's temple the ark of the covenant and even

the holy grail according to some accounts while in the new world sinclair

was worshipped as a god by the megma people who knew him under the name

gluescap

In this particular case, it does, to me, suggest that the iconography would

support this Sinclair legend.

I understand what you're saying. From my point of view, the question is, what do

you take as evidence? And the way to interpret evidence is you try to let the

evidence lead you, right? Right. So in the case of Sinclair...

I don't see that this is diagnostic of Sinclair, right?

It may be compatible with Sinclair. That's all I was asking. Right, but

that's different than being diagnostic of it. So, from my mind, this is

diagnostic of Portuguese.

From my mind, this is diagnostic of Portuguese.

While examining a strange carving in the seaside town of Overton, Nova Scotia,

Rick, Marty, and their partners have just been treated to another incredible

theory.

One that suggests that the origin of the Oak Island mystery might not be

connected to the legend of Scottish Templar Henry Sinclair, but to

Portuguese explorers who visited the area in the 1500s.

Interestingly...

This particular shape of cross is not all that common where you have the

flaring outwards of the arms You mainly see it in Portuguese crosses

It is widely believed that in addition to the Knights Templar that operated

in England France and Scotland There was a Portuguese branch that was known under

the name the Knights of Christ Could it be that it was they?

and not henry sinclair who buried precious religious artifacts on oak

island and then left behind various carvings as clues to where it could be

found i do have evidence that puts the portuguese in nova scotia between 1500

and 1580. and you know they were here then how there are a few records that

have survived in particular maps

Portuguese were great cartographers, and we've got a rich collection of maps

where they named all kinds of different areas along the coast, including this

area as well.

Although it is well known that Portuguese settlers established fishing

outposts in Nova Scotia in the 16th century, there is also compelling

evidence that Portuguese explorer João Vasco de Real found what he called the

new land of the codfish in North America as far back as 1473, nearly 20

years before Christopher Columbus's famed journey.

Could there be additional evidence linking Corte Real and the Knights of

Christ, and also a connection between his early journeys to North America and

Oak Island?

This is very interesting, though. Yeah, it is very interesting.

How Terry analyzed it fits in with several theories.

I mean, it really does. It fits in with the Portuguese theory. It fits in with

Templar theory, I mean, really well.

Is the Templar cross, the arms and the stem are the same length?

They had both kinds.

And they don't always flare out, but sometimes they do. But that would vary a

lot. I mean, there were Templars in England, Templars in Germany, Templars

in Portugal and Spain.

So they weren't all identical.

Could Rick, Marty and their partners?

have just seen evidence linking the oak island mystery to portuguese treasure

perhaps even treasure connected to the knights templar after terry explained

that this could be commemorating a meeting of cultures i said well why

couldn't it be templars and the native peoples he just didn't think the carving

was quite old enough for that but it sure looked like and i still think looks

like a templar cross

We are very grateful for you taking the time to talk to us about it. Thank you

very much.

My pleasure. Okay, let's go.

As they walk away from the Overton Stone, the Oak Island team is more

excited than ever to return to the island and resume their search.

Finding the head and shaft has allowed them to verify the exact location of the

money pit and seeing the stone carvings has offered physical evidence that the

area was very likely visited by Europeans.

as far back as the 16th century could getting to the bottom of 10x and finding

a shortcut into the money pit really be the final key they'll need to solve this

220 year old mystery

Here's the divers right here.

One day after his trip to Overton, Rick Lagina and the Oak Island team have

arranged to meet with Rob Ritzy of RMI Marine.

I'll put her over here on the left. A commercial diving company that

specializes in deep underwater surveying, construction, and salvage

operations.

So guys, this is the hole. This is the project.

10X.

Today's agenda really is clear the floor.

Pull the 27-inch. There's a section of the 27-inch casing about six feet,

right, David? Yeah.

And then we've got one riser still in whole.

That's what we're pulling right there.

Yeah. Okay.

Okay, drop the sonar through the pipe.

Earlier this year, sonar scans conducted at the bottom of the 235-foot deep

borehole, known as 10X, revealed the possibility of a large man-made chamber.

Posts.

tunnels, wooden chests, and even human remains.

Now that most of the riser pipes and other above-water obstructions have been

removed,

Ritzy and his team have been hired to clear the corroded metal and debris from

the 181-foot level of 10X.

Once done, the shaft should be safe enough for another dive team to come in.

an attempt an even deeper and more dangerous dive below the 181 foot level

and through the 27 inch wide hole that leads 44 feet down to the mysterious

underground chamber all right well let's get geared up to go diving

jonathan noyles will be today's first diver let's

clip you in first

He will be lowered into 10X by means of a dive cage that Rob Ritzy has had

custom made for today's operation.

It's a good thing we made a tight one.

Built round, just like 10X, it features a gate that will allow the divers to get

in and out of the cage quickly without having to climb up and over the sides.

Okay, bud.

You want to squinch over a bit?

Just keep from spinning anymore, Nick.

Ready to do this?

Oh, it's not just myself. I think we're all anticipating this. This is what

we're focused on this year. We want to get to the bottom of 10X.

And this is the start of that journey.

Quite a remarkable achievement, isn't it? Yeah. Oh, yeah.

It's something else.

Yeah, easy, easy.

Coming down easy.

At Borehole 10X, Rick Lagina and the Oak Island team have hired a commercial

diving company, RMI Marine, to clear away rusted pipes and other debris that

have been blocking the 27-inch portion of the shaft for decades.

It is a mission that is both complicated and extremely dangerous.

Yeah, there you go.

Even with the 400 gallon per minute pump and nearby borehole 201X, which keeps

the water in the shaft down approximately 40 feet below normal

levels,

diver Jonathan Noyles will still need to make a descent in frigid water for more

than 100 feet.

Okay, I'm heading down.

Here we go.

Because of the enormous pressure, he will only be able to work in the shaft

for not longer than 30 minutes before needing to slowly make his way back to

the surface.

When you're breathing compressed air and the nitrogen is also compressed, it goes

into solution. Dissolved into your bloodstream. And then you come up and it

comes out as bubbles, little nasty nitrogen bubbles, and they lodge in your

brain or your lungs.

During the dive, nitrogen gases become highly compressed in the human body.

When the diver is ready to surface, he or she must do so in short stages,

allowing their body to decompress.

Otherwise, the nitrogen accumulates and forms bubbles in the bloodstream.

It is a condition commonly referred to as the bends and results in the diver

experiencing joint pain, disorientation, and in the worst cases, death.

Where's he at?

He's about 25 feet now.

Thought there might be a little bit more visibility than that. Yeah, there's not

much. There's no magic bullet for this.

Visibility issues are a problem.

But they're professionals, and they're just going to have to deal with it.

To secure large debris and send it to the surface, diver Jonathan Noyles will

use a rope sling known as an octopus.

For smaller objects, he will use a steel basket, the same one that was used by

Dan Blankenship when he dug 10X more than 40 years ago.

I think you're

all good. Start bringing up the crane.

We're going to start coming up easy, buddy.

Coming to surface.

I'm working my way up here now.

Okay, it's going up and over, John.

Ready to bring the other basket up? Yeah, let's do it.

See how fully you got it. Yep, exactly.

Oh, there's the pipe.

Oh, yeah, it is.

It's just a little more cleared out there now.

Yeah. Keep coming.

Okay, let's empty this.

Now that most of the debris has been removed from the 181-foot level of 10X,

hoping for a little more sediment, the team still needs to remove one more

obstacle, a six-foot-long piece of metal casing that lines the upper portion of

the 27-inch hole.

What I'm hoping for is one simple statement.

Is the casing above the anhydrite or is it below the anhydrite? Because then at

that point...

We can develop a protocol, if you will, or a procedure.

How are we going to latch onto it and pull it out?

It could bother you right away, but what's your thoughts? How much of the

steel is above the anhydrite? On one side, it's probably about that far, and

I haven't hit anhydrite.

You think we should try pulling now?

Yeah. The thought now is to use these clamps, which bite as you exert

pressure on the upstroke.

So they'll clamp on, and we'll pull from there.

so basically rick that just cams open like that see it's can lever yeah it's

got all the edges on it it just comes on it's not going to grab that boom clamp

lock it up so you got to put tension on this yes before you clamp it off yes

are you soaked dave the hot yeah no not yet

diver dave cousins will now descend 10x in an attempt to attach the steel clamps

to the 27 inch casing.

All right, we're going to come down easy.

Once the diver attaches the clamps, which have jagged ridges that allow for

a firm hold, the boom crane will lift upwards, pulling the casing from the 27

inch hole and out of the shaft.

All right, it's coming down now on a rope.

Should be right on the ground.

Right on the ground, roger.

If we can pull a 27-inch, it's a pretty good day.

We've got another 10 minutes.

I'm struggling a bit.

What would normally be an easy operation for Dave Cousins has suddenly become

extremely difficult.

Not only is he trying to attach the steel clamps to the casing in virtual

darkness... But the steel casing is heavily corroded and slick with decades

of mud and sludge.

To make matters worse, he is almost out of time.

We got two more minutes.

Roger that.

We need to come up on the crane.

Dave Cousins has finally gotten the clamps attached.

Now the boom crane will attempt to pull the casing out of the hole.

Good to go.

Up easy. Up easy.

Coming up easy.

I'll stop.

I'll stop.

Rick Lagina's mission to remove six feet of steel casing from the 27 inch portion

of 10X has just been put in serious jeopardy.

As the boom cable began lifting on the clamps attached to the rim, one of them

came loose, leaving the casing stuck in the hole.

All right, I can give you like 30 more seconds.

It's not happening. How are we going to get it out?

Take another look later.

All right, I'm going to get your umbilical tight, and we're going to

start coming up on you.

Okay.

Unfortunately, diver Dave Cousins has no time left to make a second attempt.

The six feet of steel casing will have to remain in the hole.

You take a negative and you try to see a positive in it. We now know something we

didn't know yesterday.

We got some information, learned where we need to go from here. Because at the

end of the day, given all the difficulties, I am more firmly committed

than ever to accomplish the goal. The goal being get a diver into the cavity

to the floor at 235.

Thank you for all your efforts. You're welcome. Just want to go thank the guys.

Dave, thank you. Thank you. Thanks a lot.

Tyler. Tyler.

Okay, well, here's the thing.

Typical Oak Island. We won a few.

And it won most. I think this time we kind of lost the war.

You know what? We lived to fight another day. Let's go home.

After the dive team has completed clearing most of the obstructions from

10X. Okay, so this is 10X phase one completed, really.

Marty and Rick Lagina return to the site to review the team's progress.

Divers have been in the hole. This is nice.

In my opinion, it was marginal results.

They were intrepid. They were fearless. Look, they went down the hole. They

couldn't see their hand in front of their face. I think we have to revisit.

Show me what you got out of the hole.

Okay, so here's the 10-inch. We got about 141 plus or minus.

There's a hoist rail.

That's the limited amount of garbage they were able to pull off.

And that's it.

I think he did great, personally.

These guys did a lot of work. A lot of work. It's not easy for that pipe to be

pulled and laid down and cut in pieces.

And I think Rick feels they didn't make much progress, but I think they made a

lot of progress.

I take it this is the one we dropped.

That's the one we dropped.

This piece of anhydrite was plugged to the bottom. Well, you know what, Rick?

Effectively, what we did is we... We cored it. Yeah, we cored it.

Look at the impact forces.

You know what it would take to curl the end of that steel like that?

A lot.

Problem is this right here, Rick. I'm thinking maybe this is ground-up

anhydrite, or at least partially. I know in the subsurface, this is how it cuts.

It's really, really gummy. It drills great because it's soft, but then all of

a sudden it quits drilling because it's just... It gums everything up. It's

mush. Exactly.

If that gets on top the bit, then you pull up into it, you're stuck.

And that's what I'm kind of worried about.

Well, you know, then that begs the option of, you know, do we find a diver

to dive the 27-inch and leave the 32 option off the table?

If that could be done safely, Rick, you know, that would be great. Because once

we go in and widen that hole, you destabilize things, I guess, a little.

Rick. Marty and the Oak Island team are now faced with a grim reality.

The inability to remove the six-foot-long metal sleeve, coupled with

the instability of the anhydrite layer, has ruled out the possibility of

widening the narrow 27-inch portion of 10X.

At the end of the day, this is results-oriented, and I don't believe we

were successful.

as we should have been in order to continue that process. We have to change

the direction.

They will now need to find a diver skilled enough and brave enough to risk

their life in order to find out, once and for all, what, if anything, lies at

the bottom.

We know we can get a man down the existing 27-inch hole.

Dan Blankenship did it a dozen times.

So there may be other divers who are willing to do that.

This is a tougher nut than I realized.

Gentlemen, we're here to talk about diving today and how on earth we can get

to the bottom of that 10X into that cavity safely with a diver.

Good. Here we go.

after spending the last several days clearing out corroded riser pipes and

other debris watch it jack rick and marty lagina must now find an

experienced diver who will attempt one of the most dangerous dives in the world

to descend 181 feet through the eight foot wide steel and

cement lined casing and then down an additional 44 feet through a narrow

27-inch wide hole, all the way to what appears to be a mysterious underground

chamber.

We've got John Tapper here. He is an expert. He's going to tell us about the

technical issues with regards to getting a person into the chamber at 10X.

We are calling the dive.

There's too many obstructions here.

A professional diver, John Tapper, was brought in last year.

to help the team during their previous, though unsuccessful, attempt to reach

what Dan Blankenship, the man who dug 10X 40 years ago, described as a 10-foot

tall man-made treasure vault.

Why don't I sketch out the parameters, and then you can tell me the challenges.

The cavity is roughly 10 feet by 12 feet irregular shape.

Visibility is awful.

And in there, there are some things that we want to find out.

what they are.

There's a potentiality of a post.

There is some indication there's a chest.

And then Dan said this years ago, but it's been re-verifying that there could

be a body in there of uncertain origin and age.

Do you think he's dead, Marty?

If he's not dead, I'm out of here.

With regards to getting someone down there, the depth is a problem. After you

pass 100 feet on air, you're starting to look at nitrogen narcosis.

Nitrogen narcosis presents a very real threat to divers who descend to depths

greater than 100 feet.

It occurs as a result of breathing air under higher than atmospheric pressure

and can make divers feel as though they are intoxicated.

So we're doubling that depth of where people generally start to feel the

effect. So at 200 feet... You're drunk, basically. Basically, yes. You really

can't be 100% sure of what you're seeing.

People have seen a lot of crazy stuff underwater.

Plus, if anything does happen, you don't have the mental capacity to deal with

it. Why don't you talk about the gases?

If we switch over to the Trimix dive...

With nitrogen and oxygen for your decompression gas, if you're down there,

you're feeling much better and able to respond to what you need to do.

The TriMix breathing system blends oxygen and nitrogen with helium.

As one of the only gases not affected by depth, helium helps minimize the

possibility of narcosis and allows for a safer and more successful dive

operation.

I would not do this dive without doing it on a trimix. We still need a diver

who's qualified with nitrox and... Mixed gases.

Yes. And that's a significant step up in terms of qualification of the dive. Yes,

that's going from one end of the scale to the other. It's finding someone

skilled enough and physically qualified enough to do the dive. Yes.

John is making it clear that this is not a routine dive. This is going to take a

fully accredited kind of a specialty diver person.

And that is going to be a small amount of people.

So it's going to be a small pool to choose from. We'll find someone.

There's always somebody somewhere who can do anything.

It's just a matter of reaching out to the right person.

We'll find them.

Well, let's get on that, too.

I think we're all done here. We've got a lot to do. Let's go do it.

Agreed.

Rick, Marty, and their partners leave the war room more determined than ever

to hire a diver.

who will be able to get to the bottom of 10X.

But who will they find?

Who will have the experience and the courage to perform one of the most

difficult and dangerous underwater dives ever attempted?

And once down there, what will they find?

Next time on The Curse of Oak Island.

Hey, I found something besides iron!

What's this?

Someone used this to bury extremely high-value cargo.

This will be the first remote-operated vehicle in the cavern.

We have expectations that we're going to see man-made objects.

We're in the cavern now.

There's something.

Pretty square. Looks pretty square to me.

What is that? If they're wooden, that's irrefutable proof. That changes

everything.
