The 12 best underwater sea scooters in 2020: buying guide and selection

The Yamaha Seal Sea scooter is a great take-along for a family trip. It’s not the fastest underwater scooter, offering a speed of 2 miles per hour (3.2 km/h), but it’ll do the trick for children of 8 years and up. Adults can use it too, although you’ll be pushing the device to its limits.

The Seal even prevents your fingers from getting caught in the propellers thanks to a protective cover mesh. You still need to be careful if you or your kids have long hair though; make sure your hair is tied up!

This entry-level underwater scooter boasts a long battery life and is ideal for use in saltwater thanks to its positive buoyancy. It’s also compatible with fresh water and pool water, it’ll just sink a bit.

The Yamaha Explorer sea scooter was designed for young recreational snorkelers and divers. It can be great for shallow dives or for chasing fish. The Explorer dive scooter is actually very similar to the Seal (mentioned above).

Its battery doesn’t last as long, but the Explorer can go a little faster (4 km per hour or speed of 2.5 miles per hour) and dive a bit deeper (10 meters or 30 feet) than the Seal can.

Yamaha’s RDS series of sea scooters are destined for recreational users above 16 years of age. This particular model, the RDS 250, is the middle child of the family, sitting right in between the RDS 300 and the RDS 200.

In comparison with the RDS 300 (90-minute run time and 5 km/h speed), the RDS 250 version offers a longer battery life but is slightly slower. The RDS 200, on the other hand, offers slower speed and lesser run time (60-minute run time and 3 km/h speed).

Hence, the RDS 250 is a good compromise between speed and battery duration. All three sea scooter models feature camera mounts and a removable buoyancy control chamber. They are ideal for use in salt water.

The MagicJet is one of the best underwater scooter options in terms of price-to-performance ratio. This scooter’s maximum speed is 6.5 km/h, but you can toggle to a slower speed of 4 km/h (about 2.5 mph) depending on what you’re looking for.

Its 7000-mAh Li-ion battery allows you to glide through water for up to 60 minutes at full speed, or 100 minutes if you’re using the slowest speed. The battery takes a while to charge, you’ll need to wait about 3 hours while it charges before you can go for a second spin. However, you may buy a spare battery and quickly plug it in thanks to Aquarobot’s easy battery-changing system.

What’s interesting with this dive scooter is its 2-in-1 mode. You can attach two MagicJets together in order to go faster.

The WhiteShark Mix features a unique design in comparison with other underwater scooters. It is equipped with two powerful thrusters that can propel you through the water at over 5 km/h. All you have to do is press the double triggers to get going. If you release one or both of the triggers, the device will stop.

One of this aqua scooter’s advantages is that it’s quite lightweight at only 3.5 kg (7.7 lbs). Some users have commented that it takes a bit of time to recharge the battery, so buying an extra one to swap in could come in handy. Sublue provides great customer service in case you encounter any malfunctions.

Two speeds are available with this underwater scooter: 3.6 km/h (2.2 mph) and 6.5 km/h (4 mph). You can use it with one or two hands while you glide through the water.

Its battery can last for about 45 minutes and takes around 2 hours to charge. If you’re still deep underwater when it runs out of battery you can just let hold of it and the scooter will float up to the surface. That way you don’t have to carry it while you swim upwards.

The Trident sea scooter looks like a mini underwater plane on which you can mount a waterproof camera or flashlight.

This personal propulsion device is compatible with use in the ocean, lakes, and pools. It boasts an OLED dashboard that allows you to easily keep track of your speed, depth, temperature, and battery level.

Two different speeds are available, so you can choose to go at either 3.7 km/h (2.3 mph) or 6.5 km/h (4 mph). There’s also a sports camera mount if you want to attach your GoPro, for example.

The RoboSea SeaFlyer underwater scooter will automatically float to the surface if you let go of it.

This Yamaha sea scooter offers three different speeds that can be activated by one of the triggers on either side of the device. You can use it for up to two hours and swim through currents, all while keeping an eye on the battery thanks to a LED indicator.

The Yamaha 275L comes with four ballasts (weights) that you can add or remove depending on if you’re in fresh water or salt water. It also features pressure-valve technology, allowing the device to depressurize once you’re back up to the surface.

Other features include a safety lock and an automatic shutdown function when the diving scooter is on standby for a certain period of time.

The Yamaha Seawing II is a powerful sea scooter. It features dual motors and is able to reach an impressive maximum speed of 8 km/h (5 mph). Its lithium-Ion battery allows a total underwater run time of 40 minutes for a recharge time of 3 hours.

The Seawing II is able to reach depths of 30 meters (100 ft) and is neutrally buoyant in saltwater to maintain depth effortlessly.

It features a speed control switch to change from low gear to high gear, an OLED screen that shows the current gear and the battery level as well as a mount on which a sports camera can be fixed.

This underwater sea scooter boasts a great number of features, which can probably explain its high price tag. Dubbed a “bionic marine vehicle” by its manufacturer, the AquaJet H2 can tug you through the water at a speed of up to 9 km (5.6 mi) per hour. You can choose between three different speeds if you want to cruise more slowly. The AquaJet H2 can also dive at depths of around 65 feet.

The Hoverstar AquaJet H2’s manta ray design can be dismantled to make it easier to transport. You can store the different parts in the travel case that comes with this premium sea scooter.

If anything gets caught in the propeller, the device will automatically shut down to prevent damage. The AquaJet H2 also features various LED indicators to let you know if there are any mechanical failures, or simply for you to know approximately how much time you have left on the Li-Ion battery.

The AV-2 Evolution 2 from Apollo is an Underwater Propulsion Vehicle designed for professional underwater explorers. It is able to reach a depth of 70 m (230 ft) while offering a 100-minute battery life.

Its speed trigger allows switching between 3 different propeller speeds, with a top speed of 4.2 km/h (2.6 mph).

The AV-2 Evolution 2 also features a speed adjustment function for smooth transitions between the different speeds and a LED battery indicator.

This diver propulsion vehicle by Japanese manufacturer TUSA is destined for professional divers. It comes with a patented “hands-free saddle”, which allows you to twist or turn at will.

The scooter can also pull up to three divers at a time when equipped with the “side wings” (tow bars) accessory. According to TUSA, the scooter’s speed and run time is barely affected by the additional weight from extra divers.

In addition to being able to choose between three different speeds, you can also modify the pitch or angle of the scooter. The TUSA SAV-7 EVO-2 is also equipped with LED battery status indicators.
