10 Best Sea Scooters 2025 in the United States

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. Battery life varies by speed mode—up to 60 minutes of use on the slowest setting and significantly less on the fastest, which is typical for portable sea scooters. 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.

The self-cleaning feature to prevent corrosion is a nice touch for maintenance. The Sublue Navbow is well-suited for casual to moderate underwater exploration, combining good speed, safety features, and user-friendly design, although the weight and limited battery life at top speed are worth considering.

This 4000W dual motor sea scooter stands out for its impressive speed and power, reaching up to 8.08 mph with a strong 56 lbs of thrust. This makes it much faster than typical snorkeling speeds and capable of towing two adults, which is quite rare for sea scooters. It offers three speed modes—Eco, Cruise, and Turbo—balancing speed and battery life, with the longest run time being about 100 minutes at the slowest pace. Charging takes around 2.5 hours, which is fairly quick for a device with this power.

The design focuses on smooth, stable rides thanks to its hydrodynamic shape and auto-stabilizing buoyancy, making it easier and safer to use for families or beginners. Its weight is on the heavier side at about 25 kilograms (55 lbs), so it’s less convenient to carry around but this weight contributes to stability in the water. The scooter includes safety features like emergency cut-off and thermal protection, which add peace of mind during use.

One standout feature is the anti-glare display that shows speed, battery, and temperature, plus the ability to mount an action camera to capture underwater footage hands-free—great for adventure lovers. This sea scooter is well-suited for adults and teens looking for speed and power in their snorkeling or boat adventures, especially if stability and safety are priorities. Its weight might make it less ideal for casual or travel use, but if you want strong performance and some cool features like camera mounts, this model is a solid choice.

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.
