So right now I'm in a place called the Isla De Las Mujeres, right next to next to Cancun.

There's this place called the Underwater Museum where there are a bunch of statues buried

down to kind of help, you know, the wildlife and stuff under the ocean.

Normally when I review drones, they are the kind of drones that fly around in the air.

Today, we have an underwater drone that films things underwater in 4K.

So after we check out the footage, we'll take the drone apart and see what the water protection

One of the things that's really hard with this actually...cuz like with the drone you

can actually see which way it's oriented in the sky... you know, the lights on the propellers

With this, you don't really know what direction that it's going when you're in the water because

there's no way to orient yourself except for when it reaches the surface.

[Dan] I've got to check this out for myself.

Here we have one of the vents for the propellers.

So when it's sinking down, it's sucking the water up and shooting it out the top of the

Then we have the connector here which goes to the tether into the battery pack.

And the signal where it stores all the information.

Underneath the drone, here's the propeller that brings it up and down.

It tells us the water temperature and finds fish down to one hundred and thirty feet.

And then this is a little magnet on the front, so if you had like bait or something and you

need to drop while fishing, you can just release this from the controller and drop the bait.

In the front of the drone we have two headlights – LED it looks like – and then we have

The tether's 225 feet and it goes into that receiver there.

Then the controller is kind of like the DJI set up where you have the mount for your phone,

and then you have the controllers there on the side.

So this thing right here is called the base station.

It's actually like the WiFi emitter, cuz signals underwater don't travel.

So Bluetooth and WiFi just don't work under water very far.

So with the tethering cord – that's why we have that.

And then this transmits WiFi into the controller just like the DJI controller does.

Data storage for the footage and things, that's all stored inside the drone with internal

It makes sense though because the whole thing is waterproof instead of water-resistant.

So having the SD card slot would have been really inconvenient as far as waterproofing

One of the hugest perks about this whole set up though, is that the charging port, which

is also the same thing for the tether, the battery inside this thing can last for 2 hours.

Imagine a drone in the sky being able to last that long.

Probably one of the reasons the battery lasts so long is that the water is holding most

of the weight of the drone, and it doesn't need to support itself in the sky.

When you're driving the drone, you can't go left or right to circle around something,

you can only go forward and back and then like twist the front left and right.

So it's a little bit different than flying in the air.

So it does make things a little bit harder to control, but it's not too bad.

This thing lights up blue, but like I was explaining earlier, it doesn't really orient

yourself when you're in the water because you literally can't see it.

So basically you're just looking around you in the water, maybe you can find the bottom

of the boat you're in, but it's really hard to tell distance and stuff when you're flying

So now that' we've seen what this can do and we've explored the outside of it, you know

Let's take this thing apart and see what makes it so waterproof.

One thing to remember as we take apart this PowerRay is that it's waterproof to 30 meters,

or 98 feet, depending on what part of the world you're diving in.

Water-resistant cell phones like the iPhone or the Galaxy phones, are only water-resistant

It will be interesting to see what's inside.

There are several screws holding down the exterior plastic.

These are mostly for decoration and physical protection, since there's no waterproofing

It'll unsnap from the lower body exposing the more important components.

There are some weights attached to the lower shell.

This might keep it oriented in the water, bottom side down.

Or it might also be because this is a preproduction unit that isn't quite finished.

There is a final version for sale on Amazon today, already, and I'll link that in the

But this one's just a functional prototype.

The three different propellers are now exposed.

All the motors are concealed inside the watertight back plastic housing.

The other side of the white shell can also pull away from the watertight internals.

And now it's definitely looking more like a submarine than a drone.

There are a total of 46 hexagonal 2.0 screws holding the two plastic halves together after.

After all those screws are out, the top half can lift away.

There's still wires attached to that top tethering point.

As far as waterproofing goes, a thick green rubber ring surrounds the entire outer lip
