10 Best Underwater Scooters (October 2026)

Buy the wrong type of underwater scooter and the problems show up fast. A small, light unit with a single motor struggles to move two adults, a heavy long-range model is a chore to carry onto a boat or through airport security, and a scooter that sinks when you let go can be lost in open water. Thrust, runtime, depth rating, weight and buoyancy pull against each other, so the Best Underwater Scooters depend on whether you mostly play in a pool, snorkel on vacation or dive with tanks.

The short answer: the Sublue Mix suits most people who want a floating, dual-motor scooter that is easy to carry. The Sublue Vapor is the pick for divers who want a depth display, depth alerts and the highest thrust here, and the LEFEET P1 Lite suits travelers who want the lightest unit rated to 200 ft. The rest of the list covers longer-running dual-motor scooters, modular aluminum designs and compact budget-friendly options, with clear notes on where each one falls short.

TL;DR: top picks at a glance

• Best overall: the Sublue Mix, a floating dual-motor scooter with 22 lbf of thrust that weighs only 7.72 lb.
• Best for scuba and data: Sublue Vapor, 46 lbf of thrust, a 4.3-inch screen and two batteries in the box.
• Best for travel: LEFEET P1 Lite, about 3.9 lb with a 99.63Wh battery and a 200 ft depth rating.
• Best for speed: Sublue Navbow, 31 lbf of thrust and a 4.47 mph Turbo mode.

1. Sublue Mix: Best Floating Dual-Motor Underwater Scooter for Pool and Snorkeling

• Thrust: 22 lbf from dual motors
• Speeds: 1.2 m/s (2.68 mph) and 1.6 m/s (3.58 mph)
• Runtime: up to 45 minutes intermittent, 30 minutes continuous low, 20 minutes continuous high
• Depth rating: 131 ft
• Weight: 7.72 lb with an 11,000 mAh removable battery

Pros:

• The positive-buoyancy body floats back to the surface when released, which makes it hard to lose in open water.
• At 7.72 lb it fits in a backpack, and the battery is air transport compliant.
• Dual motors give 22 lbf of thrust, enough to pull more than one person through the water.
• The buoyancy chamber detaches for deeper dives, and a universal action camera mount is included.

Cons:

• It has only two speed settings, so there is less fine control than on the three-speed Mix Pro.
• Continuous high-speed runtime is about 20 minutes, which is short for long swims.
• Extra batteries are an optional separate purchase, so all-day use needs planning.

Best for: Snorkelers and pool users who want a floating, strap-free scooter that is easy to carry and hard to lose.

The Mix earns the top spot because it balances almost every trade-off in this category. Unlike the body-tethered designs, you can let go of it to swim freely or rest, and it floats up on its own. It also comes in Coral Pink. The carbon fiber body and automotive-grade coating make it feel more finished than the lighter plastic and aluminum units further down the list.

Compared with the Sublue Mix Pro, the Mix gives up one speed and some runtime for a simpler layout. It moves at up to 1.6 m/s, which is slower than the Sublue Navbow at 4.47 mph, but that pace suits most snorkeling and pool use. The battery is a 122Wh unit, and a one-year warranty is listed.

Choose something else if you plan to dive deep with tanks or want a depth readout. The Sublue Vapor is the better fit there, with a screen and depth alerts. If airline weight limits matter more than a floating body, the LEFEET P1 Lite at roughly half the weight is easier to pack.

2. Sublue Vapor: Best Pump-Jet Underwater Scooter for Scuba Divers

• Thrust: up to 46 lbf with pump-jet propulsion
• Speeds: 3.73, 4.97 and 6.21 mph (10 km/h top speed)
• Runtime: up to 60 minutes intermittent, about 18 minutes continuous at top speed
• Display: 4.3-inch LCD showing battery, speed, direction, temperature and depth
• Weight: 18.96 lb with two removable 13,000 mAh batteries

Pros:

• Pump-jet propulsion delivers up to 46 lbf, the most thrust of any scooter here, and can pull several swimmers.
• The 4.3-inch screen tracks battery life, speed, direction, water temperature and depth in one place.
• Depth alert and depth change rate settings stop the motor at a set depth and warn about fast ascents or descents.
• Two interchangeable batteries are included, and a fast charger option cuts charging from 3 hours to 1.5 hours.

Cons:

• At 18.96 lb it is the second heaviest scooter on the list, so it is a poor carry-on companion.
• Continuous runtime at top speed falls to about 18 minutes.
• The large body, at 21.26 inches long, is overkill for casual pool use.

Best for: Scuba divers and freedivers who want depth alerts, a data screen and strong thrust for group dives.

The Vapor is the only scooter here that treats diving safety as a feature set rather than a depth rating. The depth alert cuts the motor when you reach your set limit, and the descent and ascent rate warning references 18 m/min down and 9 m/min up. A phone app can share depth, temperature and location data, and the micro-positive buoyancy keeps it close to neutral underwater.

Against the Sublue Navbow, the Vapor's 46 lbf beats the Navbow's 31 lbf and its top speed of 6.21 mph is well above 4.47 mph. The trade-off is size and bulk, since the Navbow weighs under 10 lb. This model also comes in Dravit Grey, Aqua Blue, Grey and Blue, and the Red version reviewed here includes the extra battery.

It is the wrong choice for travelers who count every pound or for children and casual swimmers. The LEFEET P1 Lite or the Waydoo Subnado Lite fit those cases far better, at 3.9 lb and 3 lb respectively.

3. LEFEET P1 Lite: Best Ultra-Light Aluminum Underwater Scooter for Travel

• Thrust: up to 8 kgf across 4 speed modes
• Top speed: 1.6 m/s
• Battery: 99.63Wh, 100W fast charging in 1.5 hours, up to 60 minutes of cruise time
• Depth rating: 200 ft, IPX8
• Weight: about 3.9 lb with a soft carry case

Pros:

• At roughly 3.9 lb and 10.7 inches long, it packs like a laptop and carries easily underwater.
• The 99.63Wh battery meets airline carry-on rules, and a custom soft case is included.
• The 200 ft rating is the deepest here alongside the LEFEET P1 and the SMACO B2.
• 100W reverse charging turns it into a power bank that can charge a phone several times.

Cons:

• Single-motor thrust of 8 kgf is much lower than the dual-motor Sublue models.
• It does not float on its own, so it needs a wrist strap or tether to avoid loss.
• Buyer feedback on battery life is mixed, so heavy users should plan on a second battery.

Best for: Frequent flyers and snorkelers who want a light scooter with a deep depth rating.

The P1 Lite is the lightest scooter here apart from the Waydoo Subnado Lite, and it adds an anti-lost strap, a camera mount and a finger-safe propeller guard. Buyers describe it as compact, comfortable and powerful for its size, and it appeals to older snorkelers who want help against light currents without hauling heavy gear. The modular system accepts official accessories such as a Dual Rail Kit, Tank Mount, Leg Mount and SUP Mount.

Compared with the LEFEET P1, the Lite is lighter at 3.9 lb against 2.3 kg of the P1 body, wait: the P1 is lighter in the aluminum body but offers swappable 100Wh and 160Wh batteries. Treat the P1 Lite as the simpler travel-first option and the P1 as the more configurable one.

Skip it if you need to pull multiple people or want a self-floating unit. The Sublue Mix floats and has 22 lbf of thrust, which makes it the better match for group pool use.

4. LEFEET C1: Best Quick-Swap Dual-Motor Underwater Scooter for Casual Snorkeling

• Thrust: up to 8 kgf from dual motors
• Speeds: two gears, up to 1.6 m/s (3.6 mph)
• Battery: 97.2Wh airline-compliant, up to 60 minutes, swapped in about 5 seconds
• Depth rating: 100 ft (30 m), IPX8
• Weight: 6.6 lb

Pros:

• The quick-swap battery system lets you replace a pack in about 5 seconds.
• An auto-shutoff halts the propellers the moment you release the control.
• The 97.2Wh battery is airline compliant, and CE and FCC certifications are listed.
• A modular design accepts optional kickboards and inflatable floats for relaxed surface use.

Cons:

• The 100 ft depth rating is half that of the LEFEET P1 and P1 Lite.
• Thrust of 8 kgf is modest, and only two speeds are offered.
• Accessories such as the floats are optional rather than included, and the kit is listed only as a standard kit.

Best for: Pool users and casual snorkelers who want a safe, modular scooter with fast battery changes.

The C1 is the safest-feeling LEFEET for beginners because the propellers stop immediately on release and the guard is built in. Its anti-corrosion construction is aimed at saltwater use, and a one-year warranty is listed. It is a yellow plastic body, so it is less rugged than the aluminum P1 and P1 Lite.

Against the Sublue Mix, the C1 matches the 60-minute headline runtime of the Mix Pro rather than the Mix's 45 minutes, but it floats only with optional accessories. It also costs you thrust, since the Mix delivers 22 lbf.

Do not pick the C1 for dives beyond 100 ft. The LEFEET P1 Lite and SMACO B2 are rated to about 200 ft and fit that case instead.

5. LEFEET P1: Best Modular Anodized Aluminum Underwater Scooter for Swappable Batteries

• Motor: 500W brushless DC
• Speeds: four gears at 1.3, 1.5, 1.8 and 2.0 m/s, set by remote control
• Battery: 100Wh swappable (160Wh option), 100W fast charge in 1.5 hours
• Depth rating: 200 ft, IPX8
• Weight: 2.3 kg at about 314.5 x 87.5 x 80.0 mm

Pros:

• The 500W brushless motor reduces friction and noise and offers the highest top speed of the single-motor models here.
• A hard anodized aluminum body resists salt, moisture and chemicals.
• Four speed gears give finer control than most two- and three-speed rivals.
• The accessory range includes Dual Rail, Single Hand Rail, Leg Mount, Tank Mount and SUP Mount kits.

Cons:

• A thrust figure is not listed, so comparing pulling power with the dual-motor Sublue models is guesswork.
• Runtime is stated as 30 to 60 minutes depending on speed, which is a wide range.
• Maximum charging speed needs a compatible 100W PD3.0 charger and cable.

Best for: Divers who want a compact, accessory-rich scooter with a swappable battery and a 200 ft rating.

The P1 is built around customization. The accessories turn it into a diver propulsion unit, a SUP booster or a camera platform, and the swappable battery gives you a way to extend dives. It also comes in Black.

Compared with the LEFEET P1 Lite, it has a more powerful motor and finer speed control, but the Lite includes a soft case and a camera mount in the package. If you want a ready-to-use travel kit, the Lite is the easier purchase.

It is the wrong tool for people who want to be pulled along hands-free or want a floating body. The Sublue Mix Pro fits better there.

6. Waydoo Subnado Lite: Best Compact Removable-Handle Underwater Scooter for Family Pools

• Thrust: up to 14.33 lb
• Speeds: 3 gears plus cruise mode
• Battery: 98Wh, 100W fast charge in 1.2 hours, up to 50 minutes of cruise
• Size: 14.84 x 2.75 x 2.75 inches, about the size of a small soda bottle
• Weight: 3 lb

Pros:

• At 3 lb it is the lightest unit in this group and easy to hand to a child or teen.
• The 98Wh battery is airline approved, and a 100W reverse charging function can power other devices.
• The removable handle makes it simple to pack and store.
• Charging takes only 1.2 hours, the fastest of any scooter here.

Cons:

• Buyer feedback points to battery life of roughly 25 to 30 minutes at the top speed.
• Reports of trigger or button failures and slow support raise reliability concerns.
• The set includes only the main unit and handle, and a charging cord is not included.

Best for: Families who want a light pool scooter that adults and older kids can both handle.

The Subnado Lite is the simplest scooter here, and the one-handed trigger design suits younger swimmers who can swim confidently. Kids with lifejackets can also use it at the surface, according to buyer feedback. It is a single aluminum body in Blue, with a one-year warranty on the main unit and six months on accessories.

Against the Asiwo Manta, it is lighter by roughly 4.7 lb but pulls less, at 14.33 lb versus 19.8 lb of thrust. Against the LEFEET P1 Lite, it gives up depth, since no depth rating is listed.

Avoid it for serious snorkeling in open water or scuba use. The Sublue Mix or LEFEET P1 Lite are rated to specific depths and better for that.

7. Sublue Mix Pro: Best Three-Speed Floating Underwater Scooter for Longer Sessions

• Thrust: 24 lbf from dual motors
• Speeds: 2.68, 3.36 and 4.02 mph
• Runtime: up to 60 minutes intermittent, 18 minutes continuous at high speed
• Charging: 2 hours with the included fast charger
• Weight: 7.82 lb with a 122Wh battery

Pros:

• A third speed and 24 lbf of thrust give more range than the standard Mix.
• The fast charger refills the battery in 2 hours.
• The package includes a 30L waterproof backpack, smartphone mount and anti-lost lanyard.
• An LED low-battery indicator warns before the power runs out.

Cons:

• The 4.02 mph top speed is slower than the Sublue Navbow at 4.47 mph.
• It lacks the display and depth tools found on the Sublue Vapor.
• Continuous high-speed runtime is only 18 minutes.

Best for: Snorkelers who want a floating scooter with three speeds and more included gear than the base Mix.

Check current price on Amazon →

The Mix Pro uses the same floating, strap-free concept as the Sublue Mix but adds a speed, a quicker charger and a bag. It comes in Black Gold, White Gold and White. The weight difference is only 0.1 lb, so the extra features cost almost nothing to carry.

If you want maximum speed, the Sublue Navbow reaches 4.47 mph and 31 lbf. If you mostly want a simple pool toy, the standard Mix is enough.

8. Asiwo Manta: Best Dual-Motor Underwater Scooter for Light Pool Fun

• Thrust: up to 19.8 lb from dual motors
• Speeds: three settings
• Runtime: up to 35 minutes on low, about 20 on medium, 12 at maximum
• Depth rating: 131 ft
• Weight: 7.7 lb with a removable 126Wh battery

Pros:

• Dual motors with three speeds give controlled power for beginners and swimmers.
• Enclosed propeller guards, a safety leash and release-to-stop controls address common safety worries.
• The package includes a battery, charger, adapter, leash and waterproof bag.
• The integrated mount takes action cameras for filming.

Cons:

• Maximum speed lasts only about 12 minutes per charge.
• Buyer feedback on reliability and battery life is mixed, with some units reported failing after several months.
• Its 35-minute low-speed runtime trails every 60-minute model here.

Best for: Pool owners and families who want a dual-motor scooter at a gentle pace.

The Manta delivers more thrust than the Waydoo Subnado Lite and weighs about the same as the Sublue Mix. Buyers say it is easy to use and fun in the pool, and the manufacturer is described as responsive. It is also sold in Blue and White, with a warranty of six months to one year depending on the part.

Where it falls behind is runtime, since the Sublue Mix and LEFEET C1 last longer. For long outings, those are the better choices.

9. Sublue Navbow: Best High-Thrust Dual-Motor Underwater Scooter for Speed and Towing

• Thrust: 31 lbf (15 kgf) from dual motors
• Speeds: Free 2.24 mph, Sport 3.36 mph, Turbo 4.47 mph
• Runtime: up to 60 minutes intermittent, 45 minutes continuous in Free mode
• Display: OLED with battery, gear, mode, connection status and run time
• Weight: 9.92 lb with a 159Wh battery

Pros:

• Turbo mode reaches 4.47 mph, making it the fastest floating scooter here.
• 31 lbf of thrust can pull multiple people.
• The OLED screen and tiered low-battery vibration alerts keep power use visible.
• A self-cleaning feature and DTC kit allow one-hand control and reduce corrosion.

Cons:

• Turbo mode runs for only about 8 minutes before you must drop speed.
• At 9.92 lb it is heavier than the Mix and Mix Pro.
• A user reported early stoppages until the first full charge, so charge fully before the first trip.

Best for: Strong swimmers and groups who want speed and towing power from a floating scooter.

The Navbow is Sublue's fastest scooter in its own description, and the three modes, Free, Sport and Turbo, are labeled clearly. Users describe it as holding up well in salt water over long ownership. It also comes in Red.

Against the Sublue Vapor, it is lighter by roughly 9 lb but offers less thrust and no depth alarm. For scuba, the Vapor wins. For pool and snorkel fun with a lot of speed, the Navbow is the better value.

10. SMACO B2: Best Two-Speed Modular Underwater Scooter for Deep Snorkeling

• Thrust: 18.7 lbf
• Speeds: Normal 1 m/s (2.2 mph) and Sport 1.8 m/s (4 mph)
• Runtime: up to 56 minutes, 100W fast charge in 1.5 hours with a compatible charger
• Depth rating: 197 ft
• Weight: 6.6 lb with a 126Wh removable battery

Pros:

• A 197 ft depth rating is among the deepest on the list.
• The 4 mph Sport mode is quick for a two-speed model.
• The kit includes a camera mount, two handles, a wrist strap and a portable case.
• A modular structure allows diving lights and cameras to be attached.

Cons:

• The 126Wh battery requires airline approval for flights.
• The 100W charger is not included.
• Only two speeds are offered.

Best for: Snorkelers and divers who want a modular scooter with a deep rating and a carry case.

The B2 is a close alternative to the LEFEET P1 at a similar rating. It also comes in Silver. It has more included hardware but fewer speed steps.

For a floating scooter, the Sublue Mix is a better choice. For reduced travel weight, the LEFEET P1 Lite is lighter by about 2.7 lb.

Buyer's Guide: How to Choose the Right Underwater Scooter

The core trade-off is power against portability. High-thrust models such as the Sublue Vapor and Sublue Navbow move groups and fight current, while light single-motor units such as the LEFEET P1 Lite and Waydoo Subnado Lite are far easier to carry but pull less.

Before choosing, check these project details:

• Thrust: Pulling more than one person needs 20 lbf or more, as on the Sublue Mix Pro or Sublue Navbow.
• Runtime: Compare continuous runtime at your preferred speed, not just the headline figure.
• Depth rating: Scuba use calls for 197 to 200 ft, while pools and snorkeling are fine at 131 ft.
• Buoyancy: A floating body is safer in open water, while non-floating units need a strap.
• Weight and battery: Airline carry-on limits restrict batteries to around 100Wh unless approved.

Thrust and Speed

Thrust decides whether the scooter feels effortless or merely helpful. The Sublue Vapor at 46 lbf and Sublue Navbow at 31 lbf can tow several swimmers, while 8 kgf units like the LEFEET C1 suit one person at a steady pace.

Speed is a separate matter. The Sublue Mix tops out at 3.58 mph, which is comfortable for pool and reef use, while the Navbow's Turbo mode reaches 4.47 mph but drains the battery fast. Evening pool sessions under swimming pool lights are a good fit for slower, controlled modes, where the Mix and Manta shine.

Battery and Runtime

Manufacturer runtimes assume intermittent use, so continuous figures are more honest. The Sublue Mix Pro lasts 60 minutes intermittent but 18 minutes continuous at high speed, and the Asiwo Manta drops to 12 minutes at maximum speed.

Removable batteries make long days easier. The LEFEET C1 swaps in about 5 seconds, and the Sublue Vapor ships with two packs. Fast charging matters too: the Waydoo Subnado Lite refills in 1.2 hours, while the Sublue Navbow needs 3.5 hours.

Depth Rating and Buoyancy

Depth ratings split the field. The LEFEET P1, LEFEET P1 Lite and SMACO B2 are rated to about 200 ft, the Sublue Mix, Mix Pro, Navbow and Manta to 131 ft, and the LEFEET C1 to 100 ft.

Floating designs such as the Mix float to the surface when released, while the LEFEET and SMACO units rely on straps. Rinse any scooter in fresh water after salt or chlorine exposure, and owners who drain a pool at season's end with a submersible pump to drain pool should keep the scooter clear of the equipment area.

Weight and Travel Portability

Weight affects how often you take the scooter out. The Waydoo Subnado Lite at 3 lb and LEFEET P1 Lite at about 3.9 lb sit at the light end, while the Sublue Vapor at 18.96 lb is a boat or dive-trip item.

Batteries are the airline gatekeeper. The P1 Lite's 99.63Wh pack meets carry-on rules, whereas the 126Wh packs on the SMACO B2 and Asiwo Manta need airline approval. Pack footwear for rocky entries too, since a pair of men's water shoes makes shoreline starts safer.

Frequently Asked Questions About Underwater Scooters

What is the best underwater scooter for beginners?

The Sublue Mix is the easiest to start with because it floats, weighs 7.72 lb and has just two speeds. The LEFEET C1 is a close second thanks to its auto-shutoff and propeller guard. Both are better suited to new users than the 18.96 lb Sublue Vapor.

How deep can an underwater scooter go?

Ratings range from 100 ft on the LEFEET C1 to about 200 ft on the LEFEET P1 and LEFEET P1 Lite. The Sublue Mix, Mix Pro, Navbow and Asiwo Manta are rated to 131 ft. Always stay within your own dive training regardless of the product rating.

Can I take an underwater scooter on a plane?

Some can be carried on. The LEFEET P1 Lite has a 99.63Wh battery that meets carry-on rules, and the Waydoo Subnado Lite has an airline-approved 98Wh battery. Larger packs like the 126Wh battery on the SMACO B2 require airline approval, so check before flying.

How long does an underwater scooter battery last?

Headline runtimes are 35 to 60 minutes, but continuous high-speed use is much shorter. The Sublue Mix Pro lasts 60 minutes intermittent and 18 minutes at constant high speed. Spare batteries for the Sublue Mix and Vapor can extend a session.

Which underwater scooter floats?

The Sublue Mix, Sublue Mix Pro and Sublue Navbow are built with positive buoyancy and float up when released. The Sublue Vapor has micro-positive buoyancy and stays near neutral. LEFEET and SMACO models rely on straps instead.

Are underwater scooters safe for kids?

Several are designed with propeller guards, but supervision is needed. The Waydoo Subnado Lite lists kids and adults as users, and buyers report children using it with lifejackets in pools. Choose the Asiwo Manta or LEFEET C1 if you want release-to-stop control.

Final Verdict: Which Underwater Scooter Should You Buy?

Best Underwater Scooters for most buyers start with Sublue Mix: it delivers 22 lbf from dual motors, floats when released, weighs 7.72 lb and rates to 131 ft. Its main weakness is a pair of speeds and about 20 minutes of continuous high-speed runtime, which makes it less flexible than the Mix Pro.

For other uses, the Sublue Mix Pro adds a third speed and a faster charger, and the Sublue Navbow gives the strongest floating performance at 31 lbf and 4.47 mph. The Asiwo Manta and Waydoo Subnado Lite are lighter, simpler options for pool play, though buyers report mixed battery life on both.

The specialist picks are the Sublue Vapor for scuba divers who want a depth screen and 46 lbf, the LEFEET P1 Lite for carry-on travel, and the LEFEET P1 and SMACO B2 for modular 200 ft setups. The LEFEET C1 suits casual snorkeling with fast battery swaps. If you are still undecided, pick the Sublue Mix and add a spare battery.
