Robosea BIKI

First in our lineup is the RoboSea BIKI. The BIKI clearly draws its design inspiration from real fish as it’s propelled and steered by an actuating fin at the back fo the unit. When on the surface of the water the BIKI can be controlled via a wifi connection with a compatible phone. The app for this is available on both Android and iOS.

Alternatively, you can use the included remote that can allow you to control the drone underwater from up to 32 feet, but again there is no real-time video in this mode. The camera on the BIKI can record at a stunning 4k resolution and is aided in capturing scenes in the depths by two powerful lamps on the front of the unit. The unit boasts about an hour and a half of battery life but can be recharged in the same amount of time. The lens over the camera also gives the BIKI an incredible 150-degree field of view. This device can also be great for filming a scuba diver using its great video feeds.


Impressive 4k resolution

Can recharge in only 2 hours

196 foot maximum depth


Slowest drone in our roundup at 1.12mph

Least maneuverable, but easy for novices to control


Trident is one of the underwater drones from OpenRove, a company that was formed b by a team of engineers who wanted to explore an underwater cave that was rumored to contain some valuable treasures.

After days of engineering research and artistry, the engineers developed Trident, a favorite underwater drone utilized by scuba divers, recreational fishers, and undersea explorers.

Some of the fantastic features that make up the Trident underwater drone include the hydrodynamic offset thruster design that lets the drone to cruise smoothly even at top speeds. This feature makes the drone an ideal option for rapid exploration. Moreover, the hydrodynamic offset thruster design makes the drone a practical choice for exploring tight quarters.

Apart from the design, this underwater drone Amazon has a Wi-Fi supported 4.1 MP resolution cameras that let you stream and record 1080p videos. You can use the videos for recreational purposes. However, the camera might not be an ideal option for commercial video capturing.

Other outstanding features that set Trident aside of the competition include the 4 hours run time, 100m exploration depth rating, and 3.89 knots speed. These features collaborate to give you a complete exploration experience. It comes with a sturdy carry case for storage and transportation, and it charges fully in 3 hours.

This drone might not be a good option for exploring water with strong currents.

Check out this interview with the Co-Founder of OpenRov Eric Stackpole talking about the Trident underwater drone!

ThorRobotics Underwater Drone

Just like the first drone in our line up, the ThorRobotics underwater drone is on Amazon. Unlike the first one, however, this one is designed to be controlled via a hardwired connection rather than wirelessly. While this does decrease the convenience and ease of use factor, it substantially improves the stability and bandwidth of the connection between user and drone. This enables real-time video and precise control no matter how deep you go.

This drone comes with a 30-meter cable to match its maximum depth, which is about 100 feet. The cable allows the user to have precise control over the unit as it dives, and continue to maintain a camera feed even when under the water, something the BIKI couldn’t do with its wireless connection. The cable runs from the drone to the included control center that comes in a durable case and boasts both a built-in monitor and controls.

This submarine features four propellers allowing it to chug along at about 1.8 miles per hour with a battery life of about 2 hours. There is no built-in camera, however, and a GoPro must be mounted inside the unit in order to record videos. This means that the specs of the camera depend on what kind of GoPro you end up buying.

The ThorRobotics underwater drone is especially sturdy and comes in at a somewhat bulky 9 1/2 pounds. The chassis also sports a pair of powerful 300-lumen headlights to illuminate the underwater scenery.


Very sturdy steel construction

Reasonably maneuverable with 4 strong propellers


Camera not included

Pretty heavy to lug around with lots of side equipment needed

Cable restricts range


If you have been looking for a drone that can let you explore deeper than the underwater drones on our best list, then DTX2 would be a great option to consider. This drone is manufactured by Deep Trekker, a renowned company that makes excellent quality commercial grade ROVs.

The company’s DTX2 ROV is maintenance free ROV is intended for those who are looking for a drone that can help them inspect underwater pipe, military workers, or those who are hunting for treasures. DTX2 ROV can go up to a depth of 1000 feet.


Some outstanding features on this drone include 300 Lumens tracking with a camera, 400-meter cable, and four 4,000 lumens. It also features a powerful internal battery, a handheld controller, and a transport casing.

Other additional attachments that you may also want to consider include a water sampler, imaging sonar, a thickness gauge, control console, mort retrieval system, and many more attachments. You can purchase the accessories separately


The iBubble aims to be the underwater camera platform that everyone is looking for. It features a wide array of highly advanced features that make it not only exceptionally stable while filming and able to produce amazing shots, but also more environmentally friendly than many of the underwater drones on the market today

This collision avoidance also plays into the eco-friendly aspect of this drone. Having a drone with tons of spinning propellers ramming into reefs or wildlife can be pretty damaging, so the designers of the iBubble have made avoiding this a priority. They have also added sound shielding to the drone, to prevent the otherwise loud whir of the motors from disturbing wildlife.

The iBubble drone sports a one-hour battery life, which is long enough for most dives. What’s more is that it can dive to a depth of 200 feet. Unfortunately, much like the ThorRobotics drone, the iBubble does not come with a camera. You have to install a compatible GoPro yourself. Compatible models include the GoPro Hero 3 and higher.


Fastest and most maneuverable drone in the list with 8 motors

Autonomous colision avoidance and diver following

200 foot max depth


Only 1 hour of battery

Does not include a camera built in

Underwater Drone Buyer’s Guide

If you’re in the market for an underwater drone then there are a few things you should be on the lookout for. The technology is still relatively new in the consumer world, unlike the aerial quadcopter style drones that have been around for a while. Because of this, almost every drone on the market has wildly different specs, giving them very distinct advantages and disadvantages relative to each other.

Some underwater drones feature varying levels of autonomous control and collision avoidance. This is important if you plan on diving alone with the drone. If you don’t plan on regularly having a dedicated camera operator it’s a good idea to look for a drone with an autonomous follow mode. With this in mind let’s look at the different options for controlling your drone.


There are typically three types of control inputs that drones can use. Some will use a physical cable to tether the control unit to the drone, others will use a wireless connection, while others still will want to be autonomous or controlled by direct input. Depending on your goals and how much experience you have with drones you may want one controller over another.

For those looking for the simplest way to get started without too much experience, a wireless model is probably best. These offer the simplest setup and often have very simple controls to match.


The next option would be a drone that has a physical tether to the controller. Using actual cables to connect devices rather than trying to sync them wirelessly through the water offers substantially higher bandwidth and more stable connections. This means that unlike wireless connections you can get real-time video feeds even while completely submerged. This makes these types of underwater drones ideal if you’re doing work that requires you to be able to see what’s going on around the drone in real time such as inspecting the hulls of boats.


Let’s consider drones that have autonomous functionality. These are perfect, as mentioned if you plan on doing a lot of diving with your drone, but don’t plan on having someone with you who can watch over the operation or control the drone. As anyone who has gone diving knows, you pretty much already have your hands full from the activity of diving alone. Adding drone controls on top of that could be prohibitively difficult or even dangerous.


Camera quality depends on a huge number of factors, especially when underwater. The RoboSea BIKI features a built-in 4k resolution camera that has a lens which allows it to capture 150 degrees of its surroundings.

The higher frame rate will give the appearance of smoother movement in shots with fast moving fish or people. Both the Hero 5 Black and the Hero6 Black can both run at 1440p and 1080p as well, to either save storage space or to capture very high frame rate shots for buttery smooth slo-mo.
