Tonight, on the Curse of Oak Island.

The first time, somebody's gonna go down in 10X and actually go into the cavern.

What do you think is down at the bottom? Two chests and one body.

It's the first look we have at 10X. According to the legend, seven people

need to die and I'm not gonna be number seven. We're not gonna get somebody

killed in that hole.

Rick or I should go with him.

Let's go down, let's go down!

Whoa, whoa!

What's up?

There is an island in the North Atlantic Where men have been looking for treasure

for more than 200 years So far they have uncovered tunnels

booby traps Carved stones with strange symbols

a 17th century pirate treasure coin even evidence of a wooden

vault

Six men have even lost their lives trying to solve the mystery.

And, according to legend, one more will have to die before the treasure

can be found.

Let's do this.

It is another day on Oak Island.

I'm going down, Rick.

No, we're on the ladder.

Wait, wait, wait, wait, wait, wait, wait, wait, wait.

Whoa!

Amber!

A day that will directly connect the island's past with its future.

Got me down another foot or so.

One foot down.

After locating the original money pit earlier this year, Marty and Rick Lagina

have hatched a bold plan.

They will attempt to send a pair of divers down to the bottom of Borehole

10X in hopes that they can find what Dan Blankenship insists he saw when he dug

the 235-foot shaft more than 40 years ago, a man-made tunnel leading to the

money pit.

But first Rick Lagina must clear the entrance of any rusted metal or other

debris that could break off and cause serious damage It

is a dangerous operation

The metal casings that line the shaft are more than 40 years old and more

seriously corroded than anyone anticipated

You gotta watch where you're catching up on.

Okay, let's go up.

What began as a simple plan to ensure safety has become extremely dangerous.

Like most things on Oak Island, if something can go wrong, it probably

will.

Is that heavy?

The section of ladder is much heavier than Rick anticipated.

Now he has to figure out how to safely remove it from the shaft.

Let go of the rope, Palau.

Let go of the rope.

Come here, you.

Damn it.

Stop there a minute. Whoa.

Ah, that hurt.

What the hell are you coming on?

No. Oh,

that little thing.

Hang on one second.

Just don't move.

A close call.

But for Rick Lagina, it wasn't nearly close enough for him to call it quits.

Here's Javi.

There's concrete.

Concrete in it.

That's why that damn thing wouldn't cut.

Well, I didn't say it was going to be easy down there.

I know, and you were right.

Going down.

I'll tell you one thing.

I was always impressed that you and your father and Dan did this, but I'm even

more impressed now.

I learned my lesson, but all the while, no matter what I was doing down there, I

was constantly thinking, what needs doing must be done in order to get the

answers, and so we will.

Now, as they wait for the dive team to arrive, Rick, Dan, and Dave Blankenship,

and Jack Begley, gather in the war room.

They have scheduled a teleconference with Marty and Craig Tester, who are in

Traverse City, Michigan, and who claim to have some exciting information to

share with them.

I see you got the brains in there today.

Hello, Daniel.

I am, Marty.

Okay, so you've got test results for us, right?

Yes, we do.

We got the carbon dating back on the stump that we took out of the swamp.

And it's carbon dating between...

1450 and 1640.

So it's putting it back quite a ways. And definitely before the muddy pit was

discovered. I like that.

Earlier this year, diver Tony Sampson pulled a large hardwood tree stump out

of the Oak Island swamp.

If, as the data indicates, the stump was growing sometime between 1450 and 1640

AD, then it would help the team pinpoint the date the swamp was created and when

a possible treasure could have been buried on the island.

That's impressive.

Yes, it is. Well, that date jives really well with any number of theories.

And, you know, it would also tend to indicate that the swamp is man-made.

What about the money pit core that we drilled out? What about that?

I had both pieces of wood analyzed, the one, the horizontal piece that came out

in the core and the vertical piece.

And they're both coming about the same time range, 1665 to the

1900s.

1665 to 1900?

If the results of the carbon dating are correct, it means the so-called chapel

vault could be anything from a 17th century treasure vault to the remains of

a 19th century searcher tunnel.

And unfortunately, it's that huge range.

where it could have been original people or it could have been searchers.

1690 is old enough for some theories, but it doesn't fit at all with the

coconut fiber age or some of the other things that are much more ancient. So I

think the frustration is that your puzzle pieces don't fit, right?

No, they don't. Those particularly do not fit, no.

So what has it done to your 95% belief?

I would say it's dropped it down from there.

But you go to the theory that a lot of people have that there was multiple

times when the island was used.

Multiple times?

According to researchers, it is entirely possible that Oak Island was known as a

repository for gold, treasure, and other valuables as far back as the 14th

century. This may have been due in part to the island's strategic placement off

the Nova Scotia coast.

near the principal Atlantic sea lanes.

In 1897, shortly after finding the wooden vault, William Chappell kept

drilling. At a depth of 171 feet, his drill bit hit what he described as an

iron plate, one that the drill bit could not penetrate.

Could this have been another, even older treasure vault? One buried centuries

before?

Before members of his team attempt to dive to the bottom of 10X, author and

treasure hunter Jay Hutton Pulitzer has returned to Oak Island.

He is here, along with Dave Blankenship, to make a few last-minute modifications

to the diving platform Rick and the team recently constructed.

What I want to do is reinforce this.

Let's grab our screws and screw gun, and I'm going to pull off a couple pieces

here, and let's just start putting braces on.

Earlier this summer, Pulitzer came to the island and shared his theory that

the Oak Island mystery dates back much earlier than most researchers believe.

There is an ancient legend about an ancient mariner society traveling from

the Holy Land to Nova Scotia with the Ark of the Covenant.

What year are we talking?

About 582 to 596 BC.

Let's just set that up on top.

When Hutton learned of the Laginas' plan to have experienced divers try and get

to the bottom of 10X, he recommended a team he has worked with for several

years. So now I got a base to work from to put up video and comms here.

Okay. So we can watch the team.

So what's the story of the one diver? I know one diver came close to dying in

this. What happened?

His dive master didn't read his chart right.

In 1993, veteran Oak Island treasure hunter Dan Blankenship hired a diver to

repeat the dive Dan himself had done several times during the 1970s.

He wanted to confirm that what he believed he saw in the frigid darkness,

235 feet underground, was still there.

Things like wooden posts, antique tools,

chests, and even the remains of a dead body.

But when the diver Dan hired attempted the dive, everything went terribly

wrong.

He was not supposed to go below 200 feet, and he went to 235.

And he was down there for probably about 15, 20 minutes.

Although the diver was able to reach the bottom, visibility was virtually zero.

He could not see or photograph anything.

he also attempted to ascend to the surface much too fast.

And in doing so, nearly became the seventh casualty of the infamous Oak

Island Curse.

So he had a serious decompression issue.

Yeah, and he didn't know it. Nope.

And he came straight to the surface.

Oh, yep.

Decompression sickness, also known as the bends, could pose a serious threat

to the divers in 10X.

It occurs when gases like nitrogen, become highly compressed in the body

when a diver is underwater.

When they rise to the surface, they must do so in short stages, allowing their

body to decompress.

Failing to do so can cause the gases to expand and form bubbles in the

bloodstream.

This in turn leads to intense joint pain, vertigo, seizures,

and in some cases, death.

We went back in the decompression chamber about four times. He's lucky.

He's lucky he didn't die.

Yeah.

Now we got us a crow's nest, and we're lying right up over it.

Good.

Thank you, sir. No problem.

Shortly after returning to Oak Island from Michigan, Marty and Craig Tester

have joined Rick and other members of the team for a meeting with Jay Hutton

-Pulitzer and diver Dan Misoshek.

Gentlemen, we've got some exciting stuff to get prepared for. We are going to get

to the bottom of 10X, it looks like. We're going to do it with the help of

these people. I want to introduce you. You've already met Hutton. This is Dan.

Dan is a professional diver, technical diver.

Dan Mishachek, also known as Frog, is a former U.S. Army infantryman and police

officer.

He has dived all over the world in the most dangerous environments, from open

water to underwater caves.

What we really want to do, like my brother just said, is we want to get to

the bottom of 10X. So these are the three gentlemen who built 10X.

Dan designed it, and David and Dan worked in that chamber.

Dan was down in a dive suit several times. How many times were you in a 27

-inch, Dan? Too many.

About a dozen.

Well, obviously it's a good design because you came back.

Here, let me show you something.

The equipment looks something like that. Look at that.

That's him going down the 27-inch.

First dive was probably in 74, 75.

One of Dan's dives in 1976 convinced him.

to widen 10X from 27 inches to the gaping 8-foot diameter hole it is today.

Dan was down there in the 27-inch. He's in a saddle.

They had lowered him down. They were torching holes in the side to figure out

if they had gone past voids when they were driving the casing down because

they suspected at 140 and 165 that there might be a side tunnel.

Suddenly, as Dan was being lowered, 150 feet down into the shaft on an electric

hoist pressure from one of the supposed flood tunnels made the borehole begin to

collapse above his head operating the hoist at the surface was his son dave

who could hear his father's desperate calls for help over the radio

Acting quickly, Dave got his father up above the area of the collapse just in

time.

Five seconds later, and Dan would have become the island's seventh victim.

To ensure something like this would never happen again, Dan, Dave, and Dan

Henske spent the next several years widening the shaft to eight feet, down

to a depth of 181 feet.

They then reinforced the shaft with concrete for 90 feet, and then stacked

the bodies of three hollowed-out railway tanker cars all the way up to the

surface.

Unfortunately, Dan ran out of money to finish the project, leaving the hull

from 181 feet to the cavern at 235 feet, only 27 inches

wide.

We have two divers going down.

both of them on mask, video, and lights.

The diving equipment, it's the Hollis rebreathers. How big is it?

It's a canister, say... No, we're just worried about in a 27-inch hole, how

much... Can you insert with that on your back in a 27-inch hole? Do you fit?

We're going to find out.

Here's our plan to make this as safe as possible.

Before we put any diver in the hole... We're deploying a special type of sonar.

For the first time, 10X is going to be mapped in super high detail and high

def. So it's going to tell us exactly what's down there so we know what we're

dealing with.

So the $1,000 question is, what do you think is down at the bottom?

I thought I saw two chests down there.

And I saw a post that supposedly was left by the original people.

And one body.

Diver beware.

Well, we all know the history of this Oak Island. We know how many people have

died here. And according to the legend, seven people need to die, and I'm not

going to be number seven.

If it's clear, if fraud can get through, we want to put human eyes in the cavern

and hopefully put our hands on something.

Enough talk. Action.

If today isn't one of the biggest days in the 220-year search for treasure on

Oak Island, it will certainly be one of the most dangerous.

After days of planning and preparation, Rick and Marty Lagina have invited two

of the world's most experienced divers to the island to dive to the bottom of

10X.

If all goes according to plan, they will be the first people in more than 20

years to risk a descent into the 235-foot deep shaft.

But if they make it down there, will they find what Oak Island treasure

hunter Dan Blankenship claims he saw more than 40 years ago?

Ancient tools?

Oak chests filled with pirate gold?

A dead body?

Or will they find an underground chamber?

one which leads directly into the money pit.

Jump up there and hook that basket up.

Because the ladder in 10X needed to be removed for safety reasons, Rick and

Marty have arranged for the divers to each be lowered into 10X using a steel

bucket suspended from a boom truck.

Safety is paramount. You're putting people at risk, people we don't know.

people who are willing to you know quite literally endanger themselves to achieve

the goal which is to get into the cavity and find out information so we've

provided them with two boom trucks one to insert dive teams into the hole and

the other in case of catastrophic failure there's another boom truck

available to extract the divers

We're just doing final assembly right now, and then we're going to go through

our checklist, which is quite extensive.

We do this every time because it's too vital. Okay. One misstep here and...

Could be fatal underwater.

Could be fatal.

Dan and Kathy Mishoshek are former police officers and professional search

and rescue divers.

Over the years, they have conducted dozens of dives together.

recovering everything from objects and artifacts to human remains.

This is Tapper. This is backup and safety and triage.

In addition to Dan and Kathy, Hutton has invited John Tapper to serve as the

backup safety diver.

It's his job to monitor Dan and Kathy's vital signs and to get them to safety.

if anything goes wrong.

This is called a rebreather. This is basically the top of the line you can

get to rebreathe. Okay, so you're going to breathe 70% oxygen?

Well, it depends on our depth.

Okay,

so it's a computer sort of deal. Depending on your breath, it's going to

feed you the right amount.

Yeah.

Atmospheric air is mostly made up of nitrogen and oxygen.

So the diver's breathing equipment, known as a rebreather, must supply the

correct mixture of the two gases in order to sustain them underwater.

Too much or too little of either could have deadly consequences.

Nitrogen narcosis, taking on too much nitrogen.

Which is like getting drunk underwater.

Yeah. When we're adding that much oxygen, we're reducing the amount of

nitrogen. Correct. I understand that completely. But then there's oxygen

toxicity, too. Correct. We're going to keep track of our oxygen toxicity units,

and there's actually a formula for that.

Oxygen toxicity, which could cause seizures, and nitrogen narcosis.

are just two more potential dangers the team will face.

Two last safety checks. One is the automatic inflate.

And BCD.

And we're good.

All right, well, guys, you know, nothing but safety, but we're eager to find out

what you're going to find out.

These must be the sonar guys.

Hey, how's it going, guys? All right.

Rick Lagina. Nice to meet you. I'm David. David, nice to meet you. Brian

Abbott. To help identify any unusual objects that might be found at the

bottom of 10X, the team has enlisted the help of Brian Abbott and Nick Burchill

of Kongsberg Maritime, a global company that specializes in deep underwater

navigation, surveying, and investigation.

Along with the dive team, they're bringing in a scan team.

What's been thrown in that hole? What's down that hole?

How might that endanger them?

So that's why we need to insert that scanning equipment.

Okay, so debris is the issue. How good a look are we going to get at that?

Well, this is an excellent sonar because it's got different frequencies, so we're

going to be able to see some very good detail.

Then if there's piping or debris or cables or that stuff, we'll be able to

see that when we put the sonar down. You want to find that table? Yeah.

The MS-1000 scanning sonar device works by sending out fan-shaped pulses of

sound waves.

If all goes well, it will generate a computerized picture of the interior of

10X, all the way from the top of the shaft to the bottom, 235 feet below the

surface.

Okay, guys, you all ready? Nick, you ready? You ready to play?

Yeah. We're ready. Awesome. Let's get going. Let's do it.

Brian Abbott is a leading expert in using this device and devices like them.

He worked getting sonar images on the Titanic.

Okay. Ready?

Here we go. Yep.

Heads up behind you.

All right.

So it's not very heavy. What we're doing, we've got the transducer going

south here, and we're going to scan up and down in this shaft.

I think the best way to describe the MS-1000 is to call it a sonar camera.

I mean, it's going to use sound to present a visual picture.

It'll help with the dive because we can visualize the conditions in the big part

of 10X, the 8-foot diameter part, and we can also, hopefully, if we can get that

camera in there, visualize the conditions in the 27-inch hole that then

goes down to the chamber.

You're going to deploy to what?

110 feet. 110?

Okay. Okay, that's where it's 60?

Just come up at 80.

90. Counting down to 100.

You at it? Yep. So tie it up.

Secure.

Okay, I'm secure over here. All right. I'll get the sonar up and start getting

an image.

It goes around and all of a sudden this picture materializes on the screen, and

it's the first look we have at 10X.

Okay, so what I'm seeing on the bottom that's shown up nice and white, that's

debris? That's the bottom, yeah. Down here is the debris.

So we're looking at 4.1 feet roughly of debris, height of the debris.

So we got over 4 feet of debris burden. At this location, yeah.

According to Brian Abbott, there is four feet of debris covering the area of 10x

that is only 27 inches wide could this mean the dive is over before

it even begins

so

we got over four feet of debris burden at this location yeah After a scanning

sonar device confirms that over four feet of debris appears to be covering

the 27-inch-wide hole in borehole 10X, Rick and Marty Lagina fear the dive they

have gone to great trouble and expense to set up could be in jeopardy before it

even begins.

Any idea what that would be?

Not right away.

I don't know where it's coming from.

What could have been rigged here that somebody missed that could have fell

down in the hole? Nothing.

We cleaned the hole. The bottom of the hole was clean when we left, and

everything from on top was moved.

Once again, a well-planned operation on Oak Island is met with a serious

challenge.

There was a bunch of junk on the bottom, but they couldn't, because of the way

that thing focuses, they couldn't make out what it was.

Although the scanning sonar device is designed to generate precise images of

the objects it scans, the debris at the bottom of 10X appears to be so fine and

so dense that it's showing up as a single mass.

But what is it?

What is it made of?

And more importantly, can it be removed?

So what are we doing? So let's just scratch this. We can't get a look. Let's

just abort this, pull it up. We're wasting time.

Frog, Flash, I need you for a minute.

Jay Hutton Pulitzer believes there is only one way to find out what the debris

is and hopefully remove it. What I'm going to do is we're just going to get

them suited up and let's go in. We just need eyes and cameras and guns. Eyes on

target.

We're trying to read this debris, but it's not reading very well.

Okay, get suited up. We're going to go in. All right, let's go.

We're going to be flying blind a little bit, but get going in. We've got to get

eyes on it. Yeah, let's go.

Going into the dive, it's pretty apparent. It's a dangerous dive, so

you're concerned about safety issues and your goal.

Get in the 27-inch and get into the cavity.

Now look, there's danger in everything.

There's going to be more danger in going into 10X, but there's an objective.

We're going to take every reasonable safety precaution because human lives

are involved.

We're going to have a guy on the surface that's going to be monitoring the dive.

Also a trained diver who can go in and get these people if they're in trouble.

We're going to have an EMT team standing by.

We're not going to get somebody killed in that hole or injured.

We got it covered.

Truth is, we're amped up. I mean, it's exciting. Look, for the first time,

somebody's going to go down in 10X and actually go into the cavern.

If everything goes according to plan, divers Dan and Kathy Mishoshek should be

at the bottom of 10X within the hour.

But will they see the large wooden boxes and antique tools Dan Blankenship claims

he saw back in the 1970s?

Or perhaps an actual tunnel?

leading directly to the money pit?

Stairs will load you right there. Watch your feet.

Watch your feet.

Due to the amount of gear each diver needs for the operation, they will need

to be lowered down one at a time.

Ron, you got comms?

No comms.

We're not connected yet.

Don't you have comms with them?

I don't have comms until we get them both in.

There's no other way to do it.

To ensure safety and offer a constant flow of information, the communication

system, or comms, will keep the divers in constant touch with each other, as

well as the team on the surface.

The divers' comms will be tethered by means of a six-foot-long cable, while

another, much longer cable, will run from the divers all the way to the

surface.

This tethered system is considered more reliable than a wireless one, but no one

will be sure if it's working correctly until both divers are in 10X.

We're lined up. Tell me when, Marty, tell me when we cleared your pipe.

You're fine. You're clear here. Okay.

Your left side. Left side. Make sure you don't hit the lips. He's good.

Okay?

You're going to have to pay attention to your left side.

You've got to look at that riser, otherwise he's going to get hung up. You

watch the metal. You're going to get down, Frog, as you get close.

That riser over there is where the problem is going to be.

Watch your hands on that rust.

Watch your hands.

We've got to get him left. We've got to get him left.

He's got to steer himself now at this point.

come off of that channel and spin himself there you go there you go there

you go okay frog we got to do our best to keep you left all he's got to do is

stay on those channels 30 feet to water watch your band watch your hand whoa

on down watch your head

stay centered right there you got it other way back there you go there you go

let's go down let's go down let's go faster

Stop. Watch your hands. Watch your hands.

Whoa, whoa.

Get your tank inside.

Your right tank's hanging over the right side.

The dive down 10X is finally getting underway.

You got it. You're fine.

But now, the team must deal with a major issue.

Watch behind you. Just don't catch that lip.

There is very little clearance between the steel cage that diver Dan Mishasek

is being lowered in.

and the rusted metal inside the shaft.

Because

their

communication system won't be functional until both divers are in the water 40

feet below, Jay Hutton Pulitzer is unable to help Dan safely navigate his

way down.

Watch it right there. Watch the lip on the front.

Hold on, hold on, hold on.

We had state-of-the-art communication devices, but they couldn't be connected

until the divers were in the water.

So really, we had the most primitive of communications going on. We had people

hollering at each other down a 40-foot hole.

You're going to have a lip in another 10 feet.

And there was a lot of hollering going back and forth and not a lot of

communication.

Plus, the diver's communicating through a mask. Yes.

Dave, watch your guy. Now, look, you got risers underneath you and a cage. You

see them?

Okay, you got them?

Let's go down.

Let's go down.

You got this issue going on between hot and cold.

These people are basically frying in their wetsuit until they get in the

water, and then it gets really cold. You could tell by the muffled screams.

get us in the water get us in the water they were they were basically cooking in

their own juices okay let's go watch your elbow watch your

right elbow clear your right elbow clear it go down go

down he wants to go down let's go down we're going let's go down we're in stop

finally after several tense minutes diver dan michaasek also known

as frog, makes it into the water.

I'm clear, boom.

Okay, come on out.

You know what occurs to me? We should send a regular person down with him

because that person can communicate so much better and spin it. Rick or I

should go with him.

I'll go.

Rick. is riding down with you.

There's no way to have comms. We need a person in the basket because you're not

connected. So Rick's riding with you. Plus he can spin the basket right

because he knows the hole.

Let's go.

With Rick Lagina riding in the cage with Kathy, not only will he be able to help

keep the cage stable, he will also be able to relay any communications to

Kathy from the team above.

Yeah, she's overheating.

Okay, let's go.

Coming up.

For me, it was easy because you realize that they're about to do what they're

going to do, that is dive in there. And so you just do what you have to do to

alleviate that problem.

So it was more about them than it was about me.

Okay, Dave, you need to pull it your way and turn because they're going to hit

those lips otherwise.

Rick, because he's fearless, and when he's on a quest, you know, he'll do what

it takes.

Which way do you want to face them? Rick towards Dave.

Okay, we're going to twist them this way. Yep, spin them that way. Perfect.

Right above you, Frog.

Coming down, Watcher.

There's a history of danger associated with 10X.

I mean, look, Dan almost lost his life twice in that hole.

And now that danger is magnified in this dive because there's so much equipment,

things tossed in, the ladders rusted, broken riser pipes.

So we have to be very, very careful.

We got to twist it, clear this lip and clear these tines. It's got to go this

way, this way. The tines are okay. There you go, there you go, there you go.

Okay, Rick, be careful, huh? Yeah, we'll get it.

We just got to clear these lips. We're pushing.

Going down.

I'm worried.

You know, these two people are going into this hole.

We know it's got hazards in it.

I'm on the edge of my chair. I'm worried. I'm a diver myself.

There are known hazards and unknown hazards.

I would have a hard time going in that hole.

Watch your hands on the rings, Rick.

Going. Let's go down.

Watch it. Watch it.

Coming down.

For the first time in more than 20 years, divers are going to attempt a

descent to the bottom of 10X.

If successful, They might find everything from ancient tools and

treasure chests to man-made tunnels that lead directly to the bottom of the

infamous money pit.

Watch your hands on the rings, Rick.

And to make sure diver Kathy Misoshek gets into the water safely, Rick Lagina

has volunteered to be lowered down in the steel cage basket with her.

shut down for. You got to move. We got to get him in. We got to get him in.

Okay.

Down.

You in the water yet, Rick?

Water.

Okay. Say when.

You down?

How much?

Another foot, Dave. The cage must be lowered completely into the water to

allow Kathy, who goes by the nickname Flash, to climb out and begin the dive.

Good? Yeah. But to do that means, at least for a while, Rick will need to

also be submerged in water that is only 41 degrees Fahrenheit.

He has to go down and get dunked in ice-cold water. I mean, that water, it

was 40 degrees, and then he just, he went right in up to his neck, and I'm

worried.

You know how she was cooking a minute ago?

He's free.

She's not clear yet. No.

I think she's going to get it here. Her tank's looped on that one bar.

She won't come out. Her tank's looped on the bar. Rick will see it.

That's why Rick is down there.

I don't know. He came out on the right side. He came out on your left. He came

out backwards.

Turn her tanks against the wall.

Okay.

Right there, right there, right there.

What's holding her up is that side extra tank. She's got to push it down.

Push it down.

You know what?

We should get Rick a wetsuit.

He's going to freeze.

Okay. Now she's got to get out and slide to her left.

There she goes. She's clear.

You ready to come up?

Yes.

Somebody, get him a towel.

He's going to be frozen.

I didn't really feel the water because I was concentrating on getting them out.

But then when the water crept up to here, I realized just how cold that

water was.

You did a great job. That's for damn sure.

It was 41 degrees. That's cold water.

It's cold water in anybody's bucket.

Got it? Yeah.

We got a feed? Okay.

I've got the videos on.

I can see Flash and yours.

Okay, I've got you, Frog. I can see it both.

Now, with both divers in the water, their comms, or communication and video

lines, can be activated.

This will allow the team at the surface to stay in constant contact and monitor

every second of the dive.

You ready?

Myself, my brother, I mean, we've put a lot of time and energy into this island.

And, you know, for the first time, hopefully, we can get real data with

eyes on target and get information that's been denied everyone for almost

40 years.

That's pretty exciting stuff.

Okay, we're going now.

For brothers Rick and Marty Lagina, a 50-year-old fascination with the Oak

Island mystery has led... to an historic moment.

By sending divers down borehole 10X, they may be on the verge of finding out

if there really is something of incredible value buried at the bottom of

the money pit.

Give us a little more line. A little more line?

But if so, what could it be?

Gold and jewels worth millions of dollars?

Priceless religious artifacts?

Ancient documents?

containing knowledge that has been lost to man for centuries?

Or is 10X simply a trap?

A trap that will cost the brothers not only their time and money, but

possibly someone's life.

Next time on The Curse of Oak Island. Here we go.

I can't see you. I can't see you. They're in the dark. They can't see you.

Your imagination takes over. What's happening down there? I am stuck.

You saying you're caught?

Yeah. Recall the dive off.

Abort the dive. I cannot hear you.

We just came out of the pipe. They're down in the chamber. That looks like

steps. There's a chamber. Yes, with man-made objects.

Those are boxes.

What's the thing to the right of it? It looks very square.

It sure looks like a tunnel. It does look man-made. We found it.
