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.

The Sublue Mix Underwater Scooter is a solid choice for anyone looking for a versatile and user-friendly sea-scooter. It can reach speeds up to 3.36 mph, which is quite enjoyable for both kids and adults. The dual motors provide strong thrust, helping you glide smoothly underwater. Battery life offers up to 30 minutes of use if you take breaks, or 16 minutes if you run it continuously, which is decent for casual diving, snorkeling, or pool fun. A handy feature is the removable battery, making it easy to replace or carry spare power for longer adventures.

Its waterproof rating of 40 meters (131 feet) means it’s suitable for most recreational diving and snorkeling activities but may not be ideal for very deep dives. The buoyancy can be adjusted by attaching or removing the floater, allowing for different water activities and comfort levels. At 7.7 pounds (3.5 kg), it’s lightweight and portable enough to bring on trips, and the battery is safe for air travel, simplifying transport.

Safety features like a one-button start and propeller guards make it approachable for beginners, while the carbon fiber build keeps it sturdy without adding extra weight. An added bonus is the built-in action camera mount, perfect for capturing your underwater adventures. The main downsides are the limited continuous battery life and the moderate depth rating if you plan to dive very deep. For casual users and families wanting a fun, easy-to-use sea-scooter, the Sublue Mix offers great value and performance.

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.
