10 Best Sea Scooters 2025 in the United States

The Waydoo Subnado underwater scooter stands out in the sea-scooter category for its compact design and user-friendly features. Weighing just 3 lbs and about the size of a small soda bottle, it's easy to pack and carry, making it excellent for travel, including airline trips. Its advanced battery system offers rapid charging (just 1.2 hours) and a cruise time of up to 56 minutes, which is quite practical for those looking to enjoy extended underwater adventures without frequent stops to recharge. The propulsion system delivers a solid thrust of 14.33 lbs, providing a pleasant experience both for leisurely swimming and more active pursuits like snorkeling or diving.

One of the scooter's notable strengths is its versatility, as it's suitable for use in pools, diving, or even on paddle boards. It comes with a variety of accessories, including a finger-safe controller and multiple mounting options for hands-free operation, enhancing its usability for both adults and kids alike. The safe design also includes features to minimize the risk of injury, making it family-friendly.

However, there are some drawbacks to consider. While the battery life is decent, users may wish for a longer duration, especially for full-day excursions. Additionally, the depth rating of 197ft, while impressive, may not satisfy all serious divers who might require a scooter that can handle greater depths. Lastly, the warranty terms (one year for the main unit and six months for accessories) are decent, but could be a concern if users rely heavily on the included accessories.

The Waydoo Subnado is a well-rounded underwater scooter exciting for casual water enthusiasts and families. It’s compact and easy to use, making it a great choice for those looking to explore underwater environments with ease.

The Sublue Navbow+ is a professional-grade sea scooter designed for adults who enjoy diving, snorkeling, or underwater exploration. It offers three speed settings, with a top speed of about 4.47 mph, making it one of the faster models available. The scooter uses dual motors providing strong thrust (33 pounds of force), which is powerful enough to pull more than one person in the water. Battery life varies depending on speed: you can expect around 45 minutes of continuous use on the lowest speed and up to 8 minutes at the highest speed, with a total intermittent use time of about 60 minutes. The battery is removable and charges quickly within 2 hours, adding convenience for longer outings. It supports diving down to 40 meters, which suits most recreational underwater activities.

One notable safety feature is its slight positive buoyancy, meaning it will float up if you accidentally let go, reducing the risk of losing it. The scooter weighs about 9 kilograms, which is somewhat heavy, but the carbon fiber build keeps it durable. It includes an OLED display that shows real-time info like depth, speed, battery level, and water temperature, plus a digital compass and sensors to help with underwater navigation. The companion app adds useful safety alerts and lets you track and share your dive logs.

Although some users might find the weight a bit much for carrying around, the performance and smart features make the Navbow+ an excellent choice for serious water sports enthusiasts who want a reliable and tech-savvy sea scooter.

The Sublue Navbow is a strong choice for adults looking for a versatile underwater scooter. It offers three speed levels, with a top speed of 2 meters per second, which is quite fast for this type of device. The dual motors provide solid thrust, enough to pull more than one person, making it suitable for various underwater activities like snorkeling and shallow diving up to 40 meters deep.

The removable battery is a practical feature for quick swaps or charging separately.

It’s also fairly easy to handle with one hand, which is great for doing other tasks underwater, like adjusting ear pressure or taking photos. The scooter has a slight positive buoyancy, meaning it will float up if dropped, reducing the risk of losing it. The built-in OLED display and low battery alarm are helpful for keeping track of remaining power during use. On the downside, the scooter weighs around 9 kilograms, which might feel heavy to carry around for some users. While the waterproof depth rating of 40 meters suits most recreational divers, those seeking deeper dives may need a different model.
