10 Best Rated Underwater Drones Good to Go Deep

A lthough exploring equipment becomes more and more complex and performant every day, a huge part of the underworld hasn’t been discovered yet. Moreover, until recently, only researchers had access to the amazing wildlife and sub-aquatic landscapes, as the necessary gadgetry used to be highly expensive and difficult to find. However, things have changed, with drones and underwater cameras that allow us today to discover depths of up to hundreds of feet and snap astonishingly clear photos, all within the reach of our wallet.

It’s time to get in touch with a new world, and the best way to do it is through a reliable underwater drone. Before purchasing one, you should check the price, durability, and performance, and you will find all the necessary information in our article. So, read on to decide between 10 of the most appreciated models.

How does an underwater drone work?

When people hear the expression ‘underwater drone’, the first thing they imagine is one of those large rovers that are used by the military or professional underwater treasure hunters. Remember the opening scene in Titanic where a crew explored the rooms of the wrecked ship to discover the seif where Rose’s portrait was held? Well, they used a drone to retrieve it, the only difference is that it was a lot larger than the ones we analyze in this top.

The new drones designed for personal use are slim and lightweight but function on the same principle. Most of them are tied to the user through a tether that guarantees they don’t get lost at sea and come with a floating hub that ensures the Wi-Fi connection between them and a phone. They come with high-end cameras and motion sensors that allow them to record everything clearly and transmit it to your phone. Most models can stream live, so you can see the underworld in real-time.

Moreover, more advanced models are on the verge to be tested, as expert Ben Coxworth at New Atlas explains, and they are expected to use light instead of a tether to communicate with the user, which can offer better underwater exploring opportunities.

If you are looking for a portable source of energy to recharge your drone directly on the beach, we recommend investing in a portable solar generator kit. Place it in your RV or in the trunk and install the solar panels as soon as you arrive.

1. Geneinno Underwater Drone Camera

Check Price at Amazon


Specifications

  • Sensor Resolution: 8 MP
  • Video Resolution: 4K, 1080p.
  • Optical Sensor: 1/2.5” CMOS
  • Digital Video Format: MP4(H265)/MP4(H264)
  • Battery Time: 4 hours
  • Cable Length: 50 ft.
  • Water Depth Resistance: 492 ft.
  • Light: 2 x 1,500 LM
  • Speed: 2 m/s


Cutting-edge technology and a robust structure are some of the main features of Geneinno. It was designed with utmost durability in mind and can dive down to 492 feet without getting damaged by the water pressure or extreme temperatures that are found at these depths. Furthermore, it is equipped with one of the most performant cameras, so you can record high-quality videos or snap the best pictures in your life.

Strong Build

It comes with a patented underwater design and is made entirely of anti-corrosion materials, so you can use it with confidence at great depths, as long as the water pressure doesn’t overcome 1.5MPa. The 6 strong thrusters are placed in strategic positions for ultimate performance and controlled by an accurate steering algorithm that sets the optimal speed and agility necessary to resist strong currents and the harsh conditions that characterize deep dives. Besides that, everything is protected by a 1-year warranty, so you can do your favorite activities without worrying about extra expenses.

Live Stream

The integrated professional 4K camera is provided with a wide 160-degree angle lens, able to capture marvelous videos of landscapes and wildlife. Besides that, you can take super clear photos with a resolution of 8MP, all with a little help from the two 1,500-lumen lights that accompany the device. However, the best function is the live stream, and you will be able to follow your drone’s route and receive images in real-time directly to your smart devices. The information is delivered through a wireless transmitter that uses a frequency of 2.4 GHz. Plus, you won’t have to worry that the aquatic environment will mess with your pictures, as red and purple dive filters are ready to correct any distortion and deliver beautifully colored pictures and videos from depths down to 63 feet.

Excellent Independence

You can precisely control the direction and decide if you need your device to go forward, backward, upward, downward, left, or right. Apart from that, the 9,000mAh battery allows you to navigate for up to 4 hours, so you will be able to send your drone further and explore more territory. Not to mention that it runs with a maximum speed of 6.56 ft./s, so you can capture everything without getting bored. The interface is adaptable and allows you to connect it to a sonar, hydrophone, or even add a robot arm.

Performance Results – What Do Testers Say?

We tested the Geneinno Underwater Drone in a pool to see how well the camera works, if the battery is as reliable as they promise, and if it could keep a steady wireless connection while live streaming. We even tested the robotic arm Geneinno offers for a few extra hundred dollars.

First thing first, we noticed that the lights are really strong, and even if it was getting dark outside, the image on the console’s screen was clear, and we could see the turquoise of the pool’s tiles. We drove the drone around the pool, allowing it to have as much cable as it needed – no tangling incidents at all. The wide-angle camera opened to a nice panorama (kidding, it was just pool water we saw and some objects we threw inside the water to retrieve later with the arm, but the clarity of the image convinced us that this model can really capture the beauty of some nice colorful fish or corals).

We tested the arm with a bunch of balls and dog toys we had around, and it grabbed them surprisingly quickly. We used the console for the experiment, as it seemed that a smartphone would have made Geneinno more difficult to control. Plus, it felt really cool, like we were driving a real ROV towards the place where treasures were hidden. The whole adventure lasted for about 3 hours and a half when the battery needed to be recharged, which is less than what Geneinno promised, but we assumed that the robotic arm used extra energy, and this shortened the fun a bit.

6. Chasing Gladius Mini

Check Price at Amazon


Specifications

  • Sensor Resolution: 12 MP
  • Video Resolution: 4K UHD
  • Optical Sensor: 1/2.3″ CMOS
  • Battery Time: 2 hours
  • Cable Length: 164 ft./330 ft.
  • Water Depth Resistance: 328 ft.
  • Light: 2 x 1,200 LM
  • Speed: 2 m/s


With this mini drone from Chasing, the depths of the ocean will no longer represent a mystery, not for you and not for your YouTube followers, who will be able to see your recordings from their computers in real-time. It packs the latest technology and is built to last with a structure that allows it to dive at great distances underwater without being smashed by the pressure or damaged by the low temperatures.

Nature-Inspired Design

To make this drone run as smooth as possible through the water, the engineers at Chasing turned toward the features that help fish and sharks gain speed and maintain their stability. This was the starting point for adding gill-shaped drainage to the unit and shaping it in a way that allows it to move without opposing too much resistance to the water. Besides the shape, other design elements make it fast and performant, so let’s explore them briefly.

  • Five Propellers – it is equipped with 2 main propellers that allow it to navigate at high speed on the horizontal and 3 supplementary thrusters that help it go up and down into the water.
  • Long tether – you have 2 tether variants, one with a length of 50 meters and the other with a length of 100 meters. The second option will allow you to dive your drone down to 330 feet underwater, which is quite impressive.
  • Tilt Lock Mode – The combination of thrusters allows you to tilt the unit at a certain angle, and you can choose to lock it at this angle to make sure it doesn’t change direction. You will get the most amazing photos and videos with this option.
  • LED lights – the 2 LEDs are placed on the front of the drone and have a total power of 2,400 lumens, being strong enough to penetrate through the darkness and allow the camera to capture the curiosities of the underworld.

The drone moves at a speed of 2 meters per second, being just as fast as the more expensive models. To communicate with you, it uses a base with 2 Wi-Fi frequencies (2 GHz and 5 GHz), which is a welcomed bonus, seeing how most drones work only with one frequency. Unfortunately, the battery only lasts 2 hours, so you may need to recharge it several times per day if you are doing an ampler project.

UHD Camera Performance

Once you have installed the app on your phone and linked the drone to it, you can prepare to receive crisp images, as this model comes with a great camera.

  • 4K UHD films and 12 MP photos – the 1/2.3-inch CMOS F3.0 lens ensures excellent clarity, so your recordings will look great even when displayed on large screens.
  • 1080p live stream – it can send live recordings to up to 3 devices at the same time, so your friends can join in and have the same experience without having to wait until the drone is back. Plus, it works with VR goggles, so imagine what a wonderful afternoon you could have.
  • Depth-Lock Mode – once you’ve settled at a certain depth, the one that allows you to record what interests you, you can lock the drone at this level.
  • Image restoration algorithm – the water’s density and refraction tend to affect the picture color and clarity, so this algorithm will correct it so your pictures look vivid and colorful instead of some greyish, unclear snaps.

The clarity of the photos is dependent on the stability of the device, but there’s no worry here as the artificial intelligence algorithm offers impeccable control, even when the unit gets down at greater depths.

PROS

  • Biologically inspired design helps it slide through water without opposing too much resistance
  • Can tilt at 45 degrees, and you can lock it in this position to get the greatest pictures
  • An AI algorithm restores the picture’s color so they look vivid and natural
  • Clear videos can be transmitted live
  • Long tether and pressure-resistant construction allow it to dive down to greater depths

CONS

  • The battery lasts only for 2 hours
  • Some users reported that it loses connection with the app sometimes


Verdict

This is a great product that offers similar options as a high-end model but at a more affordable price. It has the latest technology in terms of stability and camera performance, although some improvements are in order and expected to happen in the following years, seeing how the battery only lasts 2 hours and the Wi-Fi connection is sometimes lost. Nonetheless, overall, it is an investment worth making.

Specifications

  • Sensor Resolution: 1080p High Definition
  • Video Resolution: 1080p
  • Optical Sensor: 1/2.9 inches CMOS
  • Battery Time: 5 hours
  • Cable Length: 328 ft.
  • Water Depth Resistance: 394 ft.
  • Light: 4 x 200 LM
  • Speed: 2 m/s


While there’s no doubt that the Geneinno Titan in our top is the most performant option, if you are interested in a cheaper model produced by the same company, the Geneinno Poseidon is undoubtedly a great pick. This drone has a slimmer design and can be used for basically the same activities as its more expensive version. It can dive down to 394 ft. and has the same amazing speed, being ready to reach up to 6.6 ft. per second.

One aspect that comes as a big surprise is that the battery can last for up to 5 hours, and this with only a 2-hour charge. It is one of the reasons for which Poseidon is often picked for projects that require longer exploration periods, but the long-lasting battery is appreciated by customers who buy this model for fun as well. The tether is long and has a non-tangle design, so the unit can move freely underwater.

It comes with the same floating buoy as the Titan, which allows you to maintain a wireless connection with the camera and get real-time pictures and videos. The camera is less performant (you get 1080p instead of 4UK resolution), but still, at 30 frames per second and with a wide 120-degree lens angle, you will get some good-quality pictures.

PROS

  • Compact design – can be easily carried on a plane
  • Offers up to 5 hours of underwater exploration
  • Can be controlled through an app that installs on your smartphone
  • Good-quality pictures and videos
  • Real-time transmissions

CONS

  • The camera doesn’t have 4K definition
  • The 1-year warranty is not the most generous


Verdict

With good speed and amazing battery life, Geneinno Poseidon is ready to provide a lot of fun for the summer. You can just place it in the travel bag, as it goes on the plane with no problem, and take it with you to any exotic destination you may choose for this year. It can even transmit live videos, so you can see what it sees in real-time.

It comes with an F1.6 lens with a 1.2.9” CMOS sensor, being able to snap 2 MP photos and record videos with a resolution of 1080p. The path through the water is opened by two 250-lumen lights, which are powerful enough to deliver quality images but won’t disturb the activities of the underwater inhabitants.

The connection between Dory and your phone is made through a WiFi buoy that floats on the water and is connected to the drone through a 49 feet tether. 49 feet is also the maximum depth this model can reach in optimal conditions. The 4800 mAh battery takes only 2 hours to charge and will give you up to one hour to study the underworld, which is pretty decent if you take into consideration the 5 ft/s speed this device can reach. Although it doesn’t come with a remote, it is easy to control through the Chasing Dory app that is available for both Android and iOS.
