Underwater scooters (also called diver propulsion vehicles) are becoming increasingly popular among freedivers and scuba divers who want to maximize their time underwater – covering more distance while conserving energy. You can use an underwater scooter to explore caves, dive deeper on one breath, and help you safely navigate through wreck dive sites. In this guide on how to choose the best underwater scooter, we’ll share our top picks and go through all considerations on what to look for when choosing a sea scooter for yourself.

    The Benefits of Owning an Underwater Scooter

The biggest benefit of diving with an underwater scooter is that they’re simply fun. You can go faster, cover more distance, and increase your bottom time all while feeling like you’re on a ride. Everyone from child snorkelers to freedivers to recreational scuba divers to technical divers will enjoy exploring the sea with an underwater scooter. Here are the specific benefits of owning one for yourself:

  • Less air/gas consumption: Since you won’t be exerting yourself as much as you typically would during a dive, you can stay down longer and surface while still feeling refreshed.
  • Sea scooters help counter against currents: If you love drift diving, you’ll enjoy it even more with an underwater scooter in your hands. The scooter allows you to maneuver in and out of currents. Or, it can simulate the feeling of a drift dive — just hang on and enjoy the ride.
  • Freedive training: Since freedivers can descend and ascend without worrying about speed limits, freedivers can use an underwater scooter to reach new depths or as a piece of safety equipment for a safety diver.
  • Snorkeling: Underwater scooters are fun to ride even as a snorkeler. You can ride them over colorful reefs without feeling tired.
  • Wreck and cave diving: Trained wreck and cave divers can use the underwater scooter to see compact spaces safely and while staying hydrodynamic.

Scuba divers and freedivers should get additional training on how to pilot an underwater scooter before riding one. Untrained divers may risk exceeding safe ascend and descend rates with an underwater scooter. While scuba diving, an underwater scooter should only be used for horizontal movement. Ascend and descend using your fins instead. TDI, PADI, SSI, and other dive agencies offer DPV/underwater scooter specific training courses. These courses will also teach you what to do if a scooter is stuck in the throttle position, becomes flooded, and how the sea scooter may affect buoyancy.


  • What to Look For in an Underwater Scooter

Construction

The best underwater scooters are made from durable materials like thick polymer or non-corrosive metals. Underwater scooters that are designed to dive deeper tend to be more robust than those meant primarily for shallow recreational divers and snorkelers. If you are traveling with your underwater scooter, you’ll want an even more sturdy underwater scooter that can handle

Buoyancy

The buoyancy of the underwater scooter will affect your overall buoyancy while you dive. It’s essential to adjust your weights accordingly when diving with a DPV — especially for underwater scooters that are negatively buoyant.

Depth Limit

If you’re a recreational scuba diver, you’ll want an underwater scooter that can reach your maximum depth. It doesn’t make sense to dive with a scooter that has a 15 foot limit at a 50 foot deep dive site. Technical divers will want an underwater scooter that can work on their deepest dives.

Speed

Some underwater scooters are faster than others and have throttle capabilities. If controlling your speed is important, invest in an underwater scooter that has multiple speed settings or a responsive throttle. Many scooters have just one speed setting.

Weight

Underwater scooters range from weighing just a few pounds to over 50 pounds. If you’re traveling with your underwater scooter, make sure it’s light enough for you to carry. You’ll also need to factor the weight for loading the underwater scooter onto the boat and walking with it if you’re venturing out on a shore dive.

Battery 

Underwater scooters typically last from 45 minutes to just over two hours with consistent use. If you’re doing back-to-back dives, ensure that you choose a sea scooter that can handle at least 90 minutes of consistent use. Travelers also need to check that their battery type is allowed to fly on airplanes.

Price

In the underwater scooter industry, the price of a quality DPV can range from $250 to $4000 and tends to have a strong correlation to its durability and features. If you are a recreational diver, a mid-range underwater scooter will probably meet all your needs. Technical and cave divers will want a very robust and high-end DPV to ensure that it doesn’t break while in a harsh underwater environment. Snorkelers and shallow divers will probably be happy with the lower priced underwater scooters. Most scooters that are below the $250 price point often break after just one or two uses and might be a waste of money.
