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 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.
