Buying An Underwater Drone: Complete Guide

Not so long ago, underwater drones were only available for well-funded marine researchers. Today, thanks to advances in technology, anyone can go diving with such a device.

What many people don’t consider:

Buying an underwater drone has several advantages and disadvantages that are important to consider before buying. To help you buy the best underwater drone, this complete guide will explain the features to look for when making your purchase.

Options to consider

When you buy an underwater drone, consider the following options:

  • Type of underwater drone
  • Water resistance
  • Camera quality
  • Battery life
  • Extras and accessories
  • Price

What kind of underwater drone?

Types of underwater drones:

  • Wired or tethered underwater drones.
  • Wireless or untethered underwater drones.

This option is important because the type of control affects many other components.

Wired Underwater Drones

Wireless drones may seem to be the better choice. However, is this really the case?

Drones with a cable can go farther.

The range that a drone can travel underwater directly relates to the length of the cable. However, there are characteristics other than the distance to consider.

Nevertheless, they are usually superior to wireless drones in this respect. The radio signal that controls a wireless drone does not transmit well in water.

This means that if the distance becomes too great, the drone will not be able to receive your signals and will no longer be controllable. Drones with cables do not have this problem.

Image transmission with a cable is better.

Wireless drones tend to have more trouble transmitting images in real-time. In some cases, wireless drones don’t have a live feed at all. Here, you can view footage only after the drone has surfaced.

Precise and extensive control.

Control of underwater drones that use a cable is more precise and extensive. Wireless drones respond only to very simple signals because of their poorer connection to the controller. With a cable, on the other hand, the signals transmit much faster.

Should you buy a wired (tethered) drone?

If real-time, high-quality transmission is important to you, you are better off with a drone with a cable connection.

Wireless Underwater Drones

Wireless drones are more autonomous and easier to control.

The advantages of wireless drones are most apparent in the area of control. The drones are more autonomous since they independently find their way back to the signal source in the event of signal loss.

Should you buy a wireless (untethered) drone?

Wireless drones are good for beginners. The control is simple and the underwater images are usually not inferior to those of a drone with cable.

You will rarely find precise control and reliable live underwater footage with wireless drones.

What is the camera quality of the drone?

If you go deeper with a drone than its maximum diving depth, you risk permanent damage or even the loss of the drone.

Do you own a camera or GoPro to mount?

With external cameras, there is a high risk of them detaching from the drone and getting lost. At the same time, you can use an underwater camera for snorkeling or diving.

Internal cameras have the advantage of being integrated to the drone controller. Also, there is no risk of losing them while diving. Whether you opt for a dedicated or integrated camera is ultimately a matter of taste.

What to look for in the camera quality?

If a built-in camera is available, it should meet certain quality characteristics:

  • Pay attention to whether the camera only records video or also images.
  • The image quality of the camera should be at least 12 megapixels.
  • Videos should be recorded at least in Full HD resolution (1080p), even better in Ultra HD (4k).
  • A wide-angle camera is also helpful, since it offers a larger field of view.

Tech Tip: Even high-quality cameras do not have a good view of the conditions in water with little to no visibility. Therefore, don’t expect top-notch shots in murky water, no matter how good the camera quality is.

Tech Tip: Video quality doesn’t always match streaming quality. With some drones, there is a difference between the resolution at which the images or videos record, and the image or video resolution seen while streaming to a smartphone. The latter can be worse.

How long is the battery life of the drone?

Too short of battery life makes a drone practically unusable. But how long should a good battery last?

In order to make the trip into the water worthwhile, the drone should have at least 2 hours of battery life. Some models can muster even more and run for up to 5 hours.

Battery Charging Time

Fast charging is at least as important as a long-lasting battery. That way, the drone will be ready to go again quickly if you need to recharge it between dives on the boat, for example.

How deep can the drone go and still be waterproof?

Not every underwater drone reaches the same maximum diving depth. Always pay attention to the manufacturer’s specifications before buying.

Why is this important?

Depending on what you want to use your drone for, a large maximum diving depth is not absolutely necessary. For example, a very shallow diving depth is usually sufficient for anglers.

Wonders of the deep sea:

Nevertheless, there are drones that are suitable for much deeper dives. Some models can dive up to 120 m deep. However, keep in mind that the cable length must also be correspondingly sufficient to actually reach this diving depth.

Why you should keep to the maximum diving depth in any case?

The diving depth is not about how deep a device can dive on its own. Instead, it tells you up to what depth a drone’s functions will still work properly.

What if the underwater drone does dive deeper?

If you go deeper with a drone than its maximum diving depth, you risk permanent damage or even losing the drone.

Is there a difference in water resistance for salt and fresh water?

Most drones can withstand saltwater without any problems. Nevertheless, to be on the safe side, check the saltwater resistance of the drone before using it in the ocean for the first time.

Does the drone come with any accessories or extras?

Underwater drones differ greatly regarding accessories and additional features.

Basic Accessories

Some items are mandatory to use the drone.

These include:

  • Batteries
  • Cables
  • Controller

Make sure that these accessories come with the underwater drone.

Some manufacturers supply a replacement battery right away. This way, you always have a replacement with you.

Manufacturer Apps

Almost all drones can connect to a smartphone by using certain apps. This allows access to the recordings. In most cases, smartphones will connect to an underwater drone.

Now you have to be careful:

The user-friendliness is not the same for all apps. In any case, make sure that the app is available for your operating system. Not all apps run on both Android and iOS.

Accessories & Addons

Depending on the price range, underwater drones have useful features and extras, such as:

  • external light for good pictures in deep water,
  • optical zoom,
  • LED lights,
  • Sensor systems such as sonar fishfinder and depth sounder,
  • Depth gauge to protect the drone from exceeding the maximum water depth,
  • Arms for fish bait, for example.

Note that these extras often increase the price of the drone. For a good deal, choose only what you actually need.

Is the underwater drone a good value for the price?

The initial cost of an underwater drone can quickly run into the thousands.

The price depends on several key factors:

Additional Features and extras

  • Camera quality
  • Battery life
  • Storage space
  • Dive depth

In other words:

The more the drone can do, the more expensive it is. This makes it all the more important to be aware of your own needs. That way, you won’t spend money unnecessarily on features you don’t need.

Recognize quality

With such an expensive purchase, you have to be able to rely on the quality. Unfortunately, there have not yet been any Stiftung Warentest or Öko Test tests on underwater drones.

Instead, it is worth taking a look at renowned manufacturers that have made a name for themselves with good products.

FAQ: Frequently Asked Questions & Answers About Underwater Drones

What is an underwater drone?

An underwater drone is a small diving robot that moves underwater by remote control. It usually has a camera integrated to take pictures of the underwater world.

What is the difference between a normal drone and an underwater drone?

Simply put, a normal drone moves through the air and an underwater drone moves in and underwater. While normal drones can move freely in the air, underwater drones often hang from a cable due to poor signal transmission in water. Last but not least, underwater drones have a much longer runtime, as they use the buoyancy of the water for locomotion and thus save energy.

Which underwater drone is the best?

That depends on your needs. For example, some drones are perfect for anglers, as they can use sonar to detect fish and distribute bait in the water. Others have excellent cameras and reach great diving depths. Still others, so-called toy models, are mainly suitable for the bathtub or in the pool due to their simple functionality and affordable prices.

Where can you buy underwater drones?

You can get the best selection of underwater drones from online retailers, such as Amazon. You can get competent advice on-site in specialty stores for fishing and diving accessories.

Are underwater drones suitable for underwater photography?

Yes, underwater drones can assist with underwater photography. In fact, this is one of the most important reasons to buy these drones. But beware: not every underwater drone has an integrated camera. Also, there are sharp differences in the image quality of different underwater drones.


As different as the purposes of underwater drones are, so are the drones themselves. Anglers, therefore, choose different models than, for example, bathtub experts or hobby treasure hunters.

If the underwater drone meets all the requirements of the buying guide, you have made the right choice!
