What Is an Underwater Drone?

There are many types of drones out there and they continue to advance. While many people think of flying drones or UAVs (unmanned aerial vehicles) when drones are being referenced, underwater drones or ROVs (remotely operated vehicles) are an option as well. Underwater drones are essentially waterproof submarine-type vehicles that can explore the ocean or other waters for you or with you. Several of the best underwater drones come equipped with cameras of varying quality to allow you to capture images and videos of your underwater adventures. There are also underwater drones that allow you to mount your own camera or light as well. Underwater drones are advancing year after year, so be sure to find the best underwater drone for your next underwater adventure. 

Underwater Drone VS Regular Drone

Regular drones are also called unmanned aerial vehicles and depending on the size, require registration with the FAA. While you will always need to check rules and restrictions in the water space you’re looking to explore, you won’t have to worry about registration with your underwater drone. Regular drones and underwater drones both often come equipped with cameras allowing you to capture your adventures. While you won’t have to learn to fly your underwater drone, it is recommended to learn the controls before you take it out for exploring. The controls are often similar between regular drones and underwater drones making the crossover easy for those looking to have a hobby in both. It’s amazing what drones can do these days, no matter what you’re looking to do with a drone, the right one is out there when you know what your requirements are. 

What to Consider With an Underwater Drone

With major price differences among the best underwater drones, it’s highly recommended to do some research before you buy. 


Price will always be a major factor to consider when purchasing an underwater drone. They can be a significant investment, but when you do a little research to ensure you get the one best suited for you, you’ll be pleased with your fun and rewarding investment. Lower price options are available at $399, but that is an option that comes without a camera and instead of a camera mount. Other options are available in the $1,000 to $2,000 range and the camera features continue to impress. 

Tether Cable

While not all underwater drones have a tether cable, many do and the length is a very important piece to consider. The shorter the tether cable, the more restricted you are in your underwater exploration. If you are looking at a tethered underwater drone, make sure it has a cable long enough to allow for the exploring you’re wanting to do. Wireless options are available, but they do have limited ranges as well. 

Underwater Camera Capabilities 

Unfortunately, being underwater can drastically affect the quality of your images or video. Sometimes, not even the best camera can assist when the water is dark or murky. Thankfully, there are underwater drones that come with not only outstanding camera options, but they have high quality lights as well. Underwater drones have lights with varying lumens so you can be sure your subject can be lit up properly. 

Battery Life

The battery life of the underwater drone must be considered because it’s likely you don’t want to interrupt your exploration just to change or charge a battery. Several of the best underwater drones have long-lasting batteries that you can typically rely on for 3-4 hours. If the underwater drone has varying speeds, the higher speeds will often reduce your underwater drone’s battery life. 

Licensing and Permits

This is where regular drones and underwater drones still differ greatly. As of right now, you do not have to register your underwater drone. While this may change in the future, you currently just need to ensure you are allowed to be in the water space you are in while following any rules or regulations for that water space. 

Explore the Waters On Your Terms 

Underwater drones can be used for many things and they can help you explore the water on your own terms. Not only are underwater drones great for exploring, but they’ve helped make it safer to do so. Waters can hold the unknown and while that’s intriguing for many, it can also be a dangerous place to be. Don’t let yourself wonder any longer, find out which of the best underwater drones will work for you and get your adventure started in no time.
