Public fascination with underwater drones is growing by leaps and bounds. The undersea world is getting increasing exposure through TV and the media and that has fueled curiosity to participate in diving and fishing and everything in the water. We are also in a technology boom that has started to create economies of scale in the production of ROVs, otherwise known as underwater drones. In other words, they are getting more and more affordable. What used to be available at relatively high prices for military, research, and commercial enterprises to trained professionals only are now possible for recreational use by the general public. So much of the undersea world has been explored so little, people now are using this opportunity to be at the forefront of discovery by purchasing a drone. Videographers, photographers, divers, and even fishermen have a great new tool. And underwater drones are so much fun to drive!

Factors to Consider When Buying an Underwater Drone

Being new on the market and having such a rich variety of specifications to digest means there is a unique set of advantages and disadvantages to evaluate before buying. There are questions concerning battery life and maximum depth. For example, is it for snorkeling or deep diving? Is the drone tethered or autonomous? How is it controlled?

Control Types

  • Physically tethered, wired cable connection — With these systems, there is higher bandwidth than the wireless models. The driver often can more discreetly control movement. This can include independent control of the camera gimbal, so that as the drone moves the camera can turn and remain focused on an object even as the drone moves past the object. Real-time video feeds can be possible which is useful for inspections of hulls and docks.
  • Wireless — These are often the simplest for a beginner to learn to operate. Controls are basic and streamlined for user-friendliness. The downside is that wireless connections are less stable and reliable and with more limited underwater range.
  • Autonomous– The drone can be set up to follow a diver automatically without real-time control input. This is great for the diver who is able to remain busy without having to focus on operating the drone. There are a few models that do this including the iBubble which is not yet for sale but scheduled for release in November 2023.

Depth Rating

Some drones are designed to operate at the surface. Most under consideration will dive below the surface and will need to operate at increased pressure from that of the surface. The camera and shell of the drone will have to be rated to handle this pressure. You need to make sure that the equipment you use is rated for the planned depth.

Battery Life


With the physical support of the underwater environment in terms of buoyancy, the rating is usually in terms of hours rather than the minutes talked about when using aerial drones. Make sure you know how long it will last and under what conditions.

Salt or Freshwater

There is some difference in tolerance between fresh and saltwater. Saltwater can cause damage to some equipment. Make sure if you are in saltwater that your drone can handle it.

Resolution is an important feature of a camera, but equally important is the lens in front of the camera. It is important to thoroughly examine those specifications. Some drones are not equipped with a camera and some will require adding one. The GoPro camera is one you can install yourself on many models.

Underwater drones have long been important and in some cases the only means to access certain underwater locations for research, military, and commercial applications. Today it is possible for fishermen, treasure hunters, and everyday recreational divers to enjoy the benefits. The best systems today have powerful cameras for video capture and batteries with a solid run time that is easy and convenient to control. The only drawback is that no good ones are very low priced. There isn’t really an entry-level sort of budget drone to break yourself in on. However, considering the price of the tools of the trade for fishing and diving these days, underwater drones are increasingly affordable. In addition, the features and user-friendliness are continuously improving.
