Are you the kind of person that looks out into the ocean and wonders what kind of mysteries there are waiting to be uncovered? Do you enjoy diving, but wish you could share the experience with others? If either of these questions resonate with you, it may be time to look into underwater drones.

Underwater drones are waterproof cameras that can operate under the water, capturing every magical moment that lies just beneath the surface. Underwater drones can be used for a variety of purposes, and each drone has its own special features that can enhance your diving adventures.

Things to Consider When Purchasing an Underwater Drone

Not sure what underwater drone is right for you?

Below we will take a look at what makes a good underwater drone and then we’ll share our top 7 picks for underwater drones currently on the market.


Price is a factor that should be weighed along with each feature of the underwater drone. While price shouldn’t be the main deciding factor, it can help you choose between two products with similar specs and special features.

Camera Quality 

The whole point of purchasing an underwater drone is to survey and capture what goes on beneath the surface, so you’ll want a drone with a high-quality camera. Keep in mind that the lighting underwater can be incredibly limited, so you’ll want a drone camera that lets in ample amounts of light.

Battery Life 

A typical dive can last about 45 to 60 minutes, depending on how deep you go. If your drone dies before the end of your dive, you’ll either have to lug around a dead machine or end your dive early.

Maximum Depth

Some drones are built for deep-sea exploration, while others are best suited for shallow diving. Consider what kind of underwater activities you’ll want to capture when weighing your underwater drone options.


Controllers can either be connected wirelessly or attached directly to the underwater drone. Wireless setups are typically simpler, and are most often found on drones meant for beginners. Wired controls give you a stronger connection, and are typically found on professional models that require more precise drone controls. There are also models with autonomous functions that allow them to follow the diver automatically. 

Special Features  

Most underwater drone models offer special features that set it apart from the rest of the products on the market. Many underwater drone manufacturers have found ways to add new technologies to their products to enhance your diving experience.
