What is a sea scooter?

A sea scooter is a compact, waterproof, battery-powered device that is able to tug you around underwater. Underwater diver propulsion vehicles (DPVs) generally boast one or two thrusters (propellers), much like underwater drones.

These devices are generally used for– but not limited to– scuba diving or snorkelling.

Here we take a closer look at each underwater scooter, providing you with important specs and other useful information.

Yamaha Seal underwater scooter for kids

Yamaha Seal seascooter

  • Battery life: 90 minutes
  • Max. speed: 3.2 km/h (2 mph)
  • Max. depth: 5 m (15 ft)
  • Weight: 5.4 kg (11.5 lbs)
  • Price: $245

Buy on Amazon

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 salt water thanks to its positive buoyancy. It’s also compatible with fresh water and pool water, it’ll just sink a bit.

Yamaha Explorer sea scooter for snorkeling

Yamaha Explorer seascooter

  • Battery life: 60 minutes
  • Max. speed: 4 km/h (2.5 mph)
  • Max. depth: 10 m (30 ft)
  • Weight: 5.2 kg (11.5 lbs)
  • Price: $345

Buy on Amazon

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 RDS250 best underwater sea scooter for adults

Yamaha RDS 250

  • Battery life: 120 min
  • Max. speed: 4 km/h (2.5 mph)
  • Max. depth: 30 m (100 ft)
  • Weight: 8.2 kg (18 lbs)
  • Price: $410

Buy on Amazon

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.

Aquarobotman MagicJet best underwater sea scooter

Aquarobotman MagicJet

  • Battery life: 100 minutes
  • Max. speed: 6.5 km/h (4 mph)
  • Max. depth: 50 m (164 ft)
  • Weight: 3.6 kg (7.9 lbs)
  • Price: $699

Buy on Amazon

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 on 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.

Sublue WhiteShark Mix best sea scooter

Sublue WhiteShark Mix Underwater Scooter

  • Battery life: 30 minutes
  • Max. speed: 5.4 km/h (3.3 mph)
  • Max. depth: 40 m (131 ft)
  • Weight: 3.5 kg (7.7 lbs)
  • Price: $699

Buy on Amazon

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 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.

Geneinno Trident Seascooter underwater diver propulsion vehicle

Geneinno Trident Seascooter

  • Battery life: 45 min
  • Max. speed: 6.5 km/h (4 mph)
  • Max. depth: 50 m (164 ft)
  • Weight: 3.7 kg (8.1 lbs)
  • Price: $799

Buy on Amazon

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 seascooter looks like a mini underwater plane on which you can mount a waterproof camera or flashlight.

Yamaha Seascooter 220Li scuba diving scooter

Yamaha Seascooter 220Li

  • Battery life: 60 minutes
  • Max. speed: 5 km/h (3.1 mph)
  • Max. depth: 30 m (100 ft)
  • Weight: 8.6 kg (19 lbs)
  • Price: $890

Yamaha’s Li series of salt water scooters (“Li” for Lithium Ion battery) are designed for professional divers and hobbyists alike. The 220Li version is the most affordable sea scooter in the Li range, priced at $890. It offers two speed levels, the fastest one being 5 km/h (3.1 mph).

The other two models, the 350Li and the 500Li, each offer faster speeds, longer run times, and can dive deeper than the 220Li. However, they’re quite a bit more expensive, at $1,090 and $1,750 respectively.

It will take about five hours to recharge the battery, but as with most other models, you can swap in an extra battery if you buy one separately.

This personal propulsion device is compatible for 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.

  • Max. depth: 20 m (66 ft)
  • Weight: 14 kg (31 lbs)
  • Price: $1,599

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.

TUSA SAV-7 EVO-2 Underwater Diver Propulsion Vehicle

TUSA SAV-7 EVO-2 Underwater Diver Propulsion Vehicle

  • Battery life: 110 min
  • Max. speed: 4.1 km/h (2.6 mph)
  • Max. depth: 70 m (230 ft)
  • Weight: 20 kg (45 lbs)

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.

Sea scooter vs underwater scooter vs Diver Propulsion Vehicle: what’s the difference?

There are a number of names for these devices.

Sea scooter, underwater scooter, and DPV (Diver Propulsion Vehicle) are used interchangeably. The terms all represent the same thing: a compact, waterproof device that is able to pull divers through water thanks to one or more propellers.

Some people also call these aqua scooters or underwater jetskis. They’re mainly used by scuba divers to quickly get around seascapes without expending too much energy, all while saving precious air for breathing. However, they’re also popular for recreational use. You can use a sea scooter for snorkeling or for simple exploration.

There are also “literal” underwater scooters that you can actually ride, and the go by the name “Breathing Observation Submersible Scooter”.

If you want to try one, you’ll most likely have to go to a touristic waterside vacation spot and rent one with a guide (see YouTube video).

Underwater scooter buying guide: things to consider

Here is a list of elements you should consider when deciding which is the best sea scooter for you.

Maximum speed

If you’re looking to gift a scooter to a child, a low maximum speed will do the trick just fine. You can aim for 3 or 4 km/h (2 to 2.5 mph) which should satisfy their crave for adventure.

For an adult, you may want to go for something that’s a little faster. Most sea scooter for adults will go up to 4 to 6.5 km/h (2.5 mph to 4 mph). However, you can find scooters that go up to 9 km/h (5.6 mph) if you have the budget.

Maximum depth

This specification isn’t too important if you’re just going to use your sea scooter to snorkel through shallow waters. If you’re an experienced scuba diver, you’ll want to opt for a scooter that can go deeper than 20 meters (over 60 feet).


If a sea scooter manufacturer states that their sea scooters have positive buoyancy, it means that the device will float up to the surface if you let it go in salt water. However, that means that it’ll sink in fresh water or lake water.

In that case, you’ll need to make sure you have enough battery to get back up to the surface if you’re in fresh water. Otherwise you will be carrying dead weight with you while you swim upwards.

Some aqua scooters have zero buoyancy (neutral buoyancy), meaning that they won’t sink or float. Of course, that’ll depend on if you’re using your underwater scooter in salt water, where it’s easier to float, or in fresh or pool water.

You can get a scooter that floats well in fresh water, and add ballasts (weights) to it if you use it in salt water to weigh it down.

In any case you don’t need to be an expert on buoyancy to know which scooter to get. Manufacturers usually clearly state which type of water their scooters are designed for.

Using an underwater scooter in seas and oceans

If you use your underwater scooter in salt water, make sure you follow the manufacturer’s cleaning instructions once you’re back on land. Salt can seriously harm your device if it’s not properly washed off!


Like you would for a regular electric scooter, make sure you pay attention to the sea scooter’s estimated maximum run time. Most devices offer at least an hour of battery life before they need recharging. The best underwater sea scooter options out there can provide you with up to two hours of run time.

If you choose an aqua scooter with lower run time, you might want to grab an extra battery with you.


Weight can be an important factor depending on who the scooter is for and where you’re going to use it. Most underwater scooters weigh under 10 kg (20 pounds), which can still be a bit heavy for kids if the scooter doesn’t float.

Keep in mind that in case you run out of battery while you’re deep underwater, you’re going to have to swim up to the surface with the weight of the scooter. You can keep an eye on the LED status indicator to avoid this if your scooter has one, but if your underwater scooter is buoyant, then it shouldn’t be a stress factor. Just make sure you know what kind of scooter you’re dealing with before you dive!

FAQ about sea scooters

Are underwater scooters safe?

As with any electric device, there are certain precautions to take. Underwater scooters are safe as long as you stay within the specified limits- maximum depth, correct battery charging, cleaning salt water off, respecting weight capacity, etc. Make sure you read all the manufacturer’s instructions before using your scooter.

How fast can an underwater scooter go?

The fastest underwater scooters can go up to 9 km/h (about 5.6 mph). Affordable sea scooter speeds generally hover around 3 to 4 km/h (2 to 2.5 mph).
