What are the Best Underwater Drones?

The underwater drone category is a new and exciting segment of drones. These drones are often referred to by ROVs (remotely operating vehicles) and are intended for professional users. They are still great for hobbyists as well as diving enthusiasts.

There are many professional uses for underwater ROVs. These include underwater filmmaking, ship inspections, and scientific research. However, their main purpose is to capture underwater footage in oceans and seas.

 What are the Best Underwater Drones

Keep in mind that these underwater drones are primarily tethered using a tether cable to a buoy or beacon at the surface. To get live video from the drone, and more importantly, to make sure it doesn’t wander off into the unknown, cable tethering is essential. Some wireless underwater drones can be used.

Water drones come with powerful headlamps that provide visibility even in submerged conditions. Many drones also have 4K cameras that allow for high-quality image capture. Additional features and add-ons that are common include FPV goggles and robotic arms.

This selection of the best underwater drones gives you a complete overview of the most popular products on the market at various price points. These drones have been broken down into two sections:

  • These are the best tethered underwater drones
  • Wireless underwater drones at their best

We have added a section on industrial and professional underwater ROVs for those who need more power or features. We also included a few options that are suitable for children and fishing.

Wired or wireless

While older underwater drones had wires, modern underwater drones have wireless technology. This gives you more freedom to explore underwater. A wired drone provides a better connection, but a rope limits you.

However, a wireless drone offers greater autonomy and can be difficult to receive signals. You can choose a wired drone if your purpose is possible. However, you should consider the antenna capabilities if you opt for a wireless drone.

Needs and Expectations

Although this is not a significant feature, it can be a useful tool in choosing the best underwater ROV. These gadgets can be used for many purposes, but their specific capabilities make them ideal for one purpose.

A drone is great for inspection and search, but others are better for 4k video vlogging. You need to set your expectations and choose the right drone for you.


There are many controllers for each drone, but the main difference between wired and wireless is in the controllers. Wireless controllers are easier and more suitable for beginners.

The wired controllers are more stable, so they can be more difficult to connect. You can choose the system that is most suitable for you, depending on your level.

Camera Quality

Camera quality is a key factor to consider. The drone’s purpose is to capture high-quality videos and pictures. For better images, a drone camera should have a wide-angle lens.

Depth Rating

A key feature of underwater drones is their depth rating. The drone’s depth rating is how deep dive it can go to produce photos and 4k videos. If it has all the other attributes, consider a drone with a high depth rating.

Salt or freshwater

Although wireless underwater drones can be used in salt water, it is important to inspect them before you buy one.

Autonomy Level

Wireless drones have a higher level of autonomy because they are more likely to lose their signal. You should ensure that your drone has high autonomy if you decide to purchase one.

Sensor Systems

The sensors that detect depth limits and lights are integrated into wireless underwater drones. They have been reported to be very useful and enhance the drone’s performance. This is why it is important to choose a drone with integrated sensors.

Top 13 Best Underwater Drones 2021

1. PowerVision PowerRay


  • Max depth: 30m (98ft)
  • Control: Wireless Remote Control
  • Camera: 4K High Definition / 12 Megapixel
  • Battery: 4 hours
  • Sonar: Yes (Optional)
  • Speed: 4 knots
  • Size: 465 x 270 x 126 mm
  • Weight: 3.8Kg

The environment of underwater travel is not conducive to high-frequency radios used for live streaming video feedback on drones.

Therefore, the PowerRay comes with a 70 meters umbilical tether cable that gently rests behind the device as it propels itself by its two horizontal props. To make it easy to change the depth, the body has a central vertical thruster that won’t cause any tangling.

Powervision powerray is possible to see into the depth, even within the first few meters. The Ray has two dimmable 450-lumen headlights that can illuminate your subject. These can be used in either in 4K Ultra High Definition, stream live in real-time in 1080p

The camera can capture images at a maximum ISO of 1600. However, the 1/2.3 inch sensor is capable of capturing more depth than the PowerRay can handle. Depending on which version you choose, 32Gb or 64Gb SD storage is available. However, you can also put your card in.

The PowerRay Explorer is the basic video-shooting drone. There’s also a PowerRay Wizard edition that adds the PowerSeeker sonar (which can detect underwater landscapes and use temperature data for identifying hotspots for fishing), a bait dropper, and a travel-friendly case. Zeiss VR One Goggles are an alternative way to explore the deep dive from the deck.

This is fun and makes it easier to enjoy the live feedback at 1080p than you can on your phone screen. However, the Explorer and Wizard versions are quite expensive in some stores. It is seen as the very best underwater drone with camera.

2. Chasing Innovation Gladius Mini


  • Max Depth: 100 meters (330 feet) or 50 meters (165 feet)
  • Control: Wireless remote, umbilical to Wi-Fi unit
  • Camera: 4K / 12 Megapixel
  • Battery: 4 hours
  • Speed: 4 Knots
  • Size: 383 x 223 x 137 mm
  • Weight Rov: 2.5Kg

The Chasing Innovation Gladius Mini comes in a backpack similar to what photographers use to transport a body and lenses.

The downside is that the protective caps for the 50 meters and 100 meters length tether cable can be easily lost. However, the drone is well-built and can be thrown in the ocean after being set up, and can take quite a few hits underwater ROV.

Chasing Innovation Glasdius Mini is easy to spot the bright color. Smart features include depth lock (which is similar to altitude hold on a flying helicopter) and 64GB storage.

Five thrusters allow the drone to respond quickly – handy as the body can be tilted up or down to view the surroundings.

The pitch can be locked, but the 4k camera and accompanying 1,200 lumen light cannot be turned separately. This makes it a pilot’s craft.

Chasing Innovation Gladius Mini is easy to use, VR compatible, and produces excellent results. The only problem is that image stabilization in rougher seas could be improved.

It’s the very best drone with remote control underwater camera and is very affordable compared to other products on the list.

High-quality video quality at 1080p f/1.6 ensures high-quality video content for blogs and social media posts. The camera has two 250-lumen light headlights. Dory’s is small and portable so that it can be carried around in your hand.

It also comes at a reasonable price. This drone offers unique features like DORY’S true color restoration algorithm, DORY’s dual play mode, compatibility with DORY’s app for live streaming, and is a good value for money.

This cheap drone allows you to explore deep dive at your own pace. It can reach a depth of 49 feet and comes equipped with an HD camera to take photos and videos. It also has a wi-fi Buoy, which stream live video in HD from below the water at 720p. It is also seen as the best Budget underwater drone.

4. Cellbee Sea Scooter

CellBee Sea Scooter Drone gives you complete control of the drone and allows you to monitor and guide underwater movements. This drone with battery life is perfect for underwater enthusiasts or parents who want to introduce their children to these sports.

CellBee is an underwater scooter that comes with an attachable Go-Pro camera stand. This allows you to capture your adventures in swift, sharp movements underwater.

The symmetrical design can reach a maximum speed of up to 4.3km/h thanks to a high-powered 360W motor. It has a single button to adjust the speed, but the guide cum drone can also be coded by parents for safety when their kids go underwater.

  • Size: 530 x 230 x 130mm
  • Weight Rov: 2.3Kg

The PowerDolphin glides on the surface like its natural name and can see both above and below. A drone operator will feel comfortable piloting because it has a phone-ready remote controller that can be used as a monitor.

PowerEgg X users will also find this app very familiar since it uses the same Vision+ 2 app. Available for Android and iOS.

The craft can remain on the surface and be propelled forward by two propellers. However, the drone equipped with a 4k camera with camera for Real-Time Viewing can also be used to look at the water from 150 degrees below the surface or 70 degrees above it.

This is similar to how an aerial drone’s camera tilt can be tilted. Because the craft is above water, wi-fi, GPS return home is possible.

You can use the PowerDolphin Standard pack if you only want to skim the surface. However, the PowerDolphin Explorer packs add a greater remote and 800m range.

The PowerDolphin Wizard edition offers the most value, with the addition of the PowerSeeker sonar device.

This can be used to map and find fish in the waterbed, as well as a bait dropping box that will increase your chances of success. This is probably the great Underwater Drone Kit with a good battery.

6. ThorRobotics 110ROV


  • Maximum Depth: 30 meters range (98 feet)
  • Control: Umbilical to the base station
  • Camera: 4K / 12 Megapixel
  • Battery: 4 hours
  • Sonar: Yes (optional)
  • Speed: 1.5 Knots
  • Size: 360 x 200 x 200 mm
  • Weight Rov: 4.2Kg

This Thor Robotics is an underwater explorer robot that is truly traditional. It is about the same size as a letter and good battery.

The 100 meters length tether cable is connected to a base station made of black plastic. This opens to reveal a monitor as well as the physical switch-gear.

The PowerVision products lack the same design elegance as the PowerVision products. This device was not designed to be used with aerodynamic drones or consumer products but for professionals.

The body contains four thrusters to give the robot the power it needs to complete a task. This allows you to direct enough force behind the robot arm to lift objects to 10Kg from below the waves.

For example, you could choose to help environmental projects by picking up litter or debris. Or, you might want to beat coastal metal detectorists by grabbing valuables that aren’t already washed up on the beach.

The camera can see what you are doing, but the lens’s focal length is so long that your hands are too close to the camera to be in perfect focus. This won’t slow you down.

The drone-equipped camera can also record in 4K UHD and provide 1080p live feedback. ThorRobotics offers alternative models with mobile phone mounts to the Ground Station. It is seen as the very best drone with battery life.

7. YouCan Robot BW Space Pro 4K


  • Max Depth: 100 meters range (330 feet)
  • Control: Wired remote to the wireless surface unit
  • Camera: 4K
  • Battery: (Up to) 5 hours
  • Speed: 3 Knots
  • Size: 380 x 348 x 168mm
  • Weight Rov: 3.9Kg

Although the BW Space Pro is not the fastest drone, it is still a high-quality product designed with photographers in mind.

BW Space Pro comes with a variety of cameras, it is equipped with a 6x zoom lens. The benefits of this lens in water are up for debate.

Although the aperture is relatively wider (f/1.5 for underwater drones), it is still a significant plus. While the four thrusters make tilting 45 degrees each way possible, the Gladius Mini can do the same thing with an additional thruster for stability.

You should also note that previous models with similar branding can’t even tilt. So be careful if you are looking for cheaper versions online.

AI object tracking is another benefit of the Pro version. The robot still has a strong frame that can be thrown into the water from the bank. Further control is via Dive App (iOS/Android), with depth hold and automatic adjusting lighting (maximum 1,380 lumens light from each headlight).

The box contains a joypad-like remote control and a clip for your phone. You can also purchase a smaller mini-tablet grip controller.

8. Geneinno Titan Professional


  • Brand: GENEINNO
  • Video Capture Resolution: 1080p
  • Optical Sensor Size: 1/2.5 inch
  • Lens Type: Wide-Angle
  • Package Dimensions:28.6 x 20.3 x 10.5 inches; 9.7 Pounds
  • Battery (hours): 4 hours

Geneinno Titan Professional has a high anti-compression force to reach deep under the sea. It is one of the most reliable underwater drones for professionals looking to do long, deep-water explorations.

The drone-equipped 4K UHD Camera is included with the AUV. It features a professional 1/2.5 inch CMOS image sensor that allows for high-quality photos.

It is equipped with professional DSP image processing and a 160deg wide-angle lens. Live view can be accessed via 1080P output. Its 6 reliable and powerful replaceable propellers and its smart hovering mode ensure that you get a clear shot of your target no matter what happens to it.

Geneinno can lenght up to 150 meters below the surface and run for up to 4 hours. This gives you plenty of time to explore the underwater world, return to the surface with enough battery and more than enough to last.

9. PowerVision PowerEgg X Wizard


  • Camera: 4K UHD
  • Battery: 4 hours (handheld) / 30 mins (in-flight)
  • Weight Rovs: 581g
  • Dimensions: 9.8 x 8.8 x 14.8 cm

Although it is not an underwater drone, the PowerEgg X deserves to be mentioned as it can land on the water’s surface, fly through rain, and even spray.

It also has equipped a 4K UHD 60fps camera. If you have the budget and space in your ship’s cabin, this can give you a fantastic view of the ocean deep as well as the sky above.

This drone is not an underwater drone. You will need to register with the aviation authority to operate it. However, it is a cost worth paying.

10. SwellPro SPRY+


  • Camera: 4K UHD / 12MP
  • Battery: 15 mins
  • Weight: 538g
  • Dimensions: 234 x 249 x 89 mm

The SwellPro SPRY+ drone can fly from a boat for many reasons. The entire drone is waterproof, even the controller. There’s also a built-in monitor, so you don’t have to take your phone off the deck.

Yacht owners were considered at every stage of Spry’s development. Even the return-to-home feature will always focus on the controller rather than the take-off point.

Despite the difficulties of surfing, the drone still has the features that make it a sports drone. This does not mean that you can view the live preview in analog video.

This means that there is no digital lag, so ATTI flying is more accessible for maximum speed enthusiasts. However, the live video quality remains a standard definition. Other features like wi-fi or GPS are also included.

Waterproofing requires some compromises. Although the 4k camera is electronically stabilized behind a plastic shield, it can catch flares and water drops from surface landings.

It is still built around a Sony sensor that can record 12MP stills and video at 4K camera 30fps to 720P 240fps to the onboard memory card.

While the drone acts as a wi-fi hub to the 4k camera, the remote control can be used for additional features such as waypoints. There are separate apps that allow you to change the 4k camera settings and controller settings. It is a bit fiddly, but it is worth the effort to get a highly capable drone.

11. Geneinno Trident S2


  • Camera: None, but has GoPro mount
  • Control: Held by pilot
  • Max speed: 2.67mph / 4.3km/h speed
  • Battery: 45mins (11,000mAh rechargeable)
  • Weight: 538g
  • Dimensions: 504mm x 270mm x 148mm

The Trident underwater scooter is for you to explore the deep and not just take pictures. The S2 is built with a large lithium battery that will propel you through the water. It also has simple controls.

Photographers are not forgotten; the GoPro mount is on the front. This allows you to record your trip by simply screwing on your underwater cam in the housing. It’s nice to save on an old camera, and it’s even nicer to know that you can upgrade as needed.

You can drive the Trident by simply pressing on the triggers at each end. It’s so easy that you can even remotely monitor your children while it prevents submersion. It can dive in normal use, but it will float if you let it go, even with a GoPro attached. This is the greatest underwater drone GoPro.

12. ThorRobotics U-625 Mariana


  • Max Depth: 3 meters (10ft)
  • Control: Umbilical to Wi-Fi unit, remote with phone holder
  • Camera: 1280 x 1024px
  • Battery: 10 minutes
  • Weight: 800g
  • Size: 256mm x 160mm x 80mm

This product is limited to two thrusters and won’t compete with the grown-up products in terms of maneuverability. However, it’s not a problem given the range.

The drone must continue moving forward to descend (the thrusters are at a slight downward angle), so it is best to pilot in spirals. You can either turn the thrusters backward or tug the duck antenna gently.

It is disappointing that the LED lights around the camera need to be turned on manually before the drone can be deployed. The ABS hull is sealed with a waterproof seal. However, the remote control at 2.4GHz isn’t very high quality. You can still clip in your phone to view the FPV camera and record images.

Although it may be a little rough around the edges, the product is still fun and should be something that a parent or child can bond over at least until the NiMH battery runs out!

13. Qysea Fifish V6

QYSEA’s FIFISH V6 professional underwater drone is available. QYSEA, a Chinese drone manufacturer, is the maker of the FIFISH V6. In 2019, the FIFISH V6 was launched.
