The 9 Best Sea Scooters
Updated by · How we research
Batteries under 100 watt-hours usually fly carry-on. Nine sea scooters compared on thrust, speed, run time, depth and kids' safety; the Waydoo Subnado leads. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.
Headline run times often assume stop-and-go use; at top speed, one scooter here lasts 18 minutes and another holds turbo for eight, so look for the continuous-running figure. A sea scooter, also called an underwater scooter or diver propulsion vehicle, is a battery-powered thruster that pulls you through the water without kicking. Snorkelers, scuba divers and families use them to cover more distance.
From the manual
- It sinks if you let go underwater, so keep the wrist strap on. pp. 5, 17
- Grease the cover over the USB-C port before use; a dry or badly seated cover lets water into the port. p. 9
- Charge time depends on your charger: about 1.2 hours at 100 watts, about 10 hours on a 10-watt charger. p. 9
- Below 37.5 percent charge it leaves Super gear, and below 25 percent it drops from high to low gear on its own. p. 6
Why the Waydoo Subnado is our top pick
The Subnado wins on travel and depth. Its 98-watt-hour battery sits under the 100-watt-hour line for carry-on bags,1,4 while our runner-up, the Sublue Mix Pro, carries a 122-watt-hour pack that its maker says needs airline approval.3 Our pick weighs about 3 pounds against nearly 8 for the runner-up with its float,1,3 and it's rated to about 200 feet, where the Mix Pro stops at 131.1,3
The tube is also simple to live with. A 100-watt USB-C charger fills it in about 1.2 hours, though a 10-watt charger takes about 10, and it can charge a phone in return.1 After 15 seconds of steady running, cruise mode lets you release the trigger and keep going.1 The same 98-watt-hour body comes in Lite and Standard versions, so either one you get flies the same way.2
The Mix Pro is still the better choice for a nervous swimmer. With its float fitted it rises to the surface if you let go, though the float is meant only for the top 16 feet, and its battery swaps out for a spare.3 The Subnado sinks when released, so use the wrist strap its manual recommends, and its battery is sealed inside.1

Editor's Notes
November 4, 2026, by Ezvid Wiki Editors:
We read the user manuals for seven of the nine picks, added a spec table, a section on why the Waydoo Subnado leads, and notes from each manual under its pick. We corrected the P1 XR's run time and dropped the claim that it floats, removed unsourced run-time figures from the Mix Pro entry and an unsourced five-second battery swap from the C1, and added the Mix Pro and Navbow to the list of batteries that need airline approval.
October 16, 2026, by Ezvid Wiki Editors:
The Waydoo Subnado is the new No. 1 because it's light, its battery is small enough for carry-on bags, and it suits snorkelers and divers alike. The sea scooter market has turned over almost completely since the 2021 ranking. The Yamaha Seal, Yamaha Explorer, Yamaha RDS250, Yamaha 275L and Yamaha 500Li are no longer available, and the Hoverstar Underwater is unavailable. We couldn't confirm the Aquarobotman MagicJet is still made, and the Geneinno Trident now costs far more than lighter scooters with better owner feedback. The Sublue Whiteshark became Sublue's Mix line, and the Tusa SAV-7 moves to special honors as a professional tool.
The Sublue Mix Pro is the friendlier pick for surface swimmers because it floats, and the Sublue Vapor is the one for speed.
Plenty of readers ask about scooters for children. The Nautica Skipper is the only kids' model we'd point to, and it's for ages 8 and up, with an adult watching.
A word on evidence: we found few independent tests, and several maker sites wouldn't load for us. We relied on makers' thrust, speed and battery specs, the dive site DIVEIN's published pool tests, owner reports and a recall check, and we say in each entry where a fact comes from the maker alone.
Earlier notes
October 21, 2020, by Edmund Dawson:
Before purchasing the right sea scooter, you need to consider all manner of factors to ensure you get the right one for your needs. For example, if you're interested in a fun water toy to give your kids some excitement on your next holiday, you don't need a top-of-the-range powerhouse that goes to depths of 150 feet. You'd be better off with either the Yamaha Seal or the Yamaha Explorer, the former being more suited to pools. These models come with good safety features too, such as dual trigger controls and automatic shut-off, so they can't operate the vehicle without using both hands and should they try, it would stop working. They often have positive buoyancy too, so if they let go, it will float to the surface and not sink to the bottom.
Older kids and travelers may opt for models like the Hoverstar Underwater or the Geneinno Trident as their compact size and relatively light weight means they can be stored in backpacks and taken on airplanes along with your mask and fins. The former is better for snorkeling as it only has a depth range of up to 16 feet, while the latter is a good scuba choice as it will last the duration of most fun dives and even has a camera mount for documenting your trips underwater.
We included the sturdy Yamaha 275L, as it's a go-to choice for a dive schools. It can take a few knocks, and is designed for frequent use like everyday classes doing back-to-back dives. It's speed and depth are also suited to the kind of dives you're likely to go on while taking certification courses. The Yamaha 500Li has a lithium-ion battery so will let you go on longer dives to a similar depth, while the Yamaha RDS250 is probably the best all-rounder, balancing a leisurely top speed and 100 feet range with a more affordable price than the other two.
Finally, we included the Tusa SAV-7 for very experienced (and rich) divers who need the ability to ride hands-free, with the option of towing up to two other divers, and with a long battery life that will still function in very deep waters.
Safety is paramount when it comes to using these vehicles. If you're using them while scuba diving, it is best to attend a course first to learn exactly how to manage this kind of machine safely. You will ascend or descend far too quickly if you point them directly up or down, which can cause serious equalisation problems such as a broken eardrum at best, and decompression sickness (DCS) or even an arterial gas embolism (AGE) at worst. Never put weights on your sea scooter to balance your trim, for if you accidentally let your vehicle go, you will no longer have neutral buoyancy and may ascend too quickly. Always plan your trips carefully by applying the rule that one third of your battery should get you to where you want to go, one third will get you back, and the last third is for emergencies. Sea scooters with an LED display showing battery life are best for planning this way.
Special Honors
TUSA SAV-7 EVO TUSA's SAV-7, now in its EVO3 generation, is a professional scooter that a diver straddles and steers hands-free from a saddle, with fold-out wings that let a buddy tag along. TUSA lists a range of nearly 6 miles and a working depth of about 230 feet, which suits long training and exploration dives. tusa.com
Seabob German maker Cayago builds the Seabob, a luxury jet-powered water sled that pulls riders on the surface and underwater at speeds well beyond handheld scooters. It costs many times more than the scooters here and is sold through dealers, but it's the benchmark many buyers compare against. seabob.com
Pick The Type That Fits How You Swim
They pack small and suit divers and travelers, but they float only a little or not at all, so a wrist strap or tether matters.
Sea scooters, also called diver propulsion vehicles or DPVs, come in a few distinct shapes (Wikipedia). Slim handheld tubes, such as the Waydoo Subnado and LEFEET P1 Lite, weigh roughly 3 to 5 pounds, use one motor and are controlled with a thumb button or a remote. They pack small and suit divers and travelers, but they float only a little or not at all, so a wrist strap or tether matters.
Twin-motor scooters with two side-by-side thrusters, such as the Sublue Mix Pro and LEFEET C1, weigh about 6 to 10 pounds and are held with both hands. Some, like the Mix Pro with its float fitted, rise to the surface when released, which makes them friendly for snorkelers and beginners.
At the top end, pump-jet scooters like the Sublue Vapor push harder and carry screens, but they weigh close to 20 pounds. Professional hands-free scooters and luxury water sleds cost far more and sit outside this list.
Kids' seascooters, such as the Nautica Skipper, run at about 1 to 2 mph, are rated for shallow water and need both triggers held to run. Nautica's Guppy is sold for ages 5 and up and runs at 1.2 mph for about 30 minutes, but owner feedback on it is weak. A roundup from Snorkel Around the World gives a good sense of how the older Yamaha and Tusa models fit into these groups.
Speed, Run Time And Battery Size
Treat makers' figures as best-case. Most consumer scooters list top speeds of about 3 to 4.5 mph, and the fastest here reaches about 6 mph. When the dive site DIVEIN ran scooters in a pool, they generally came in somewhat under their claimed speeds, and some top gears only last a minute or so before stepping down. Thrust is quoted in kilograms or pounds of force, sometimes per motor and sometimes in total, so compare carefully.
Run time claims are usually for stop-and-go use or the slowest gear. At full speed, many scooters here run 8 to 20 minutes before the battery is flat. If you want long sessions, look for a swappable battery and budget for a spare.
Battery size also decides whether you can fly with a scooter. U.S. rules allow lithium-ion batteries up to 100 watt-hours in carry-on bags, while batteries from 101 to 160 watt-hours need the airline's approval, and anything larger is barred from passenger planes (FAA PackSafe; Wetpixel). Spare batteries must never go in checked bags. The Waydoo Subnado and LEFEET C1 are under 100 watt-hours, and the LEFEET P1 Lite is rated at exactly 100. The Sublue Mix Pro, Waydoo Subnado Plus, Sublue Navbow and LEFEET P1 XR need approval, and the Sublue Vapor stays home. Check your airline's rules before you book.
Safety, Training And Care
A scooter can move you up or down faster than you'd swim, so on scuba you have to manage depth and buoyancy while you drive it. Annie Crawley, who teaches DPV courses and wrote Scuba Diving magazine's 2022 guide to them, says a diving scooter needs to be neutrally buoyant at depth and clipped on with a quick-release you practice before the dive (Scuba Diving). If you dive with one, take a DPV course first; PADI's takes two dives and covers ascending or descending too fast (PADI). Watch your depth gauge and never go deeper than your training allows. Keep hair, straps and fishing line away from propellers, and let go to stop.
For children, choose a model made for their age, with a grille over the propeller and a trigger that stops the motor on release, and stay within reach. Adult scooters pull with roughly 14 to 46 pounds of force, too much for young kids.
Check recalls, especially on a used scooter. In March 2025, Sublue recalled about 40,000 black lithium-ion batteries sold for the Sublue Mix and WhiteShark Mix, which can overheat and catch fire; owners can get a free gray replacement (CPSC). Sublue says the Mix Pro takes the same battery as the Mix, so check the color of any spare that comes with a used one (Sublue). We found no recalls for the other brands here.
After salt water, rinse the scooter in fresh water, dry the contacts before charging and keep battery covers and O-rings clean. Buoyancy changes between salt and fresh water, so a scooter that floats in the sea may sink slowly in a lake.
How we researched this
We screened 27 current and discontinued sea scooters and compared makers' published specs for 10 finalists. We read the manuals for seven of the nine picks: Waydoo's Subnado manual (Polish edition), LEFEET's P1 Lite, P1/P1 XR and C1 manuals, Sublue's Vapor and Navbow+ manuals, and Sport Dimension's manual covering the Nautica Skipper; the Mix Pro and Subnado Plus have no manual online, so their figures come from Sublue's and Waydoo's spec pages. DIVEIN's pool tests, the FAA's lithium battery rules and PADI's DPV course outline mattered most beyond those. CPSC and Health Canada searches found one recall touching this list, the March 2025 recall of black batteries for the older Sublue Mix, and none for Waydoo, LEFEET, Nautica or the other Sublue models.

Frequently asked questions
What is the best sea scooter for kids ages 5 to 12?
For ages 8 and up, a model built for kids, such as the Nautica Skipper, with a grille over the propeller, dual triggers that stop it on release and a top speed of about 2 mph. For younger children, Nautica's Guppy is sold for ages 5 and up, but owner feedback is weak. Always supervise closely.
What is the fastest sea scooter?
Among consumer scooters, the Sublue Vapor lists the highest top speed here, about 6.2 mph. Luxury water sleds such as the Seabob go faster but cost many times more.
Can I take a sea scooter on a plane?
It depends on the battery. Under 100 watt-hours is generally allowed in carry-on bags, 101 to 160 watt-hours needs airline approval, and larger batteries can't fly on passenger planes. Spare batteries never go in checked bags.
What happened to Yamaha sea scooters?
Yamaha-branded seascooters, including the RDS250, Explorer and 500Li, are no longer sold new by the retailers we checked. Sport Dimension, which built Yamaha's seascooters under license, now makes Nautica-branded ones such as the Skipper.
How long does a sea scooter battery last?
Makers quote about 45 to 90 minutes, but that usually assumes stop-and-go use or the slowest speed. Running continuously at top speed, many scooters last 8 to 20 minutes.
Do I need training to use a sea scooter?
Not for snorkeling at the surface, though basic swimming skills matter. For scuba, a DPV specialty course is a good idea, because a scooter can change your depth quickly.
