Top 6 Best Underwater Scooters Under $600

For casual snorkelers, families, and beginner divers, an underwater sea scooter makes exploring reefs or pools a breeze. These battery-powered scooters (“sea scooters”) add fun and speed with minimal effort. We’ve rounded up 6 top picks under $600 that balance affordability, safety, and performance. You’ll see models designed for kids (like Nautica’s compact scooters) alongside more powerful dual-motor units. Specs like speed, depth, and run-time vary – for example, one model “glides through the water” at up to 3.4 mph. Read on for details, pros, cons, and a handy comparison chart to help you choose the best affordable underwater scooter.

Sublue WhiteShark Mix Underwater Scooter

The Sublue WhiteShark Mix is a dual-motor tow-body DPV that delivers serious fun. Its two 8.8 lbf motors (17.6 lbf total thrust) can push you up to about 3.4 mph, letting you zip around at depths to 131 ft. The Mix is compact and easy: just press two trigger buttons and go. It comes with a detachable buoyancy float (for positive buoyancy) and a safety leash for extra security. A built-in GoPro-style camera mount lets you record your adventures. Batteries are easily swapped – one pack gives about 30 minutes of run-time (or up to 1 hour at lower speed).

• Pros: Powerful dual motors (17.6 lbf thrust) mean smooth gliding even when towing another diver. Includes buoyancy tank and safety leash. Built-in camera mount. Portable (folds into duffel). Fairly quick charge (≈3.5 h).
• Cons: Heavier than some kids’ scooters (unit + battery ≈7.7 lb). High-speed runtime is only 30 min. Near the $600 limit ($550 retail) – it’s one of the pricier picks. Max depth 40 m (131 ft) is good but beaten by a few competitors.

Asiwo Manta Underwater Scooter

The Asiwo Manta is a new favorite for families and snorkelers. It’s very lightweight (about 7–9 lb with its standard battery) and has positive buoyancy, so it floats up if you let go. The Manta has three speed settings (low/medium/high), ranging from about 0.6 m/s (1.3 mph) to 1.5 m/s (3.35 mph). In testing, users found it easily towed full dive gear and even another diver – an unexpected power for such a small scooter. It has a built‑in child-safety switch (kids must unlock it) and a front camera mount. With the standard 126 Wh battery it runs up to 35 min on low speed (and only 12 min on high). A double-size battery (252 Wh) is optional for extended dives (almost 70 min low speed), at the cost of extra weight. The Manta’s ease of use and safety features (positive buoyancy, tether, safety lock) make it great for beginners.

• Pros: Very lightweight and travel-friendly (7.7 lb with 126 Wh pack). Three speed modes let kids and adults adjust pace safely. Positive buoyancy and a child-lock keep it safe for family use. Up to 40 m depth rating. Affordable ($429 retail).
• Cons: Shorter run-time on high speed (only 12 min at top speed
  unless you pay for the larger battery). Not as high-thrust as bigger DPVs – better for snorkeling than heavy scuba. (However, it impressed divers with its towing ability.)

Geneinno Trident Underwater Scooter

The Geneinno Trident (S1) is a powerful dual-propeller scooter with neutral buoyancy. It cruises at two speeds (about 2.2 mph low, 4.3 mph high), and delivers roughly 26 lb of thrust – plenty to pull you through water or even a slow diver. At low speed it can run roughly 45 minutes (fast speed 25 min) on its 130 Wh battery. The Trident’s real standout is its deep dive rating (164 ft) and strong build. It includes a child safety lock switch and an integrated GoPro mount. It’s heavier (8.2 lb) than the Manta, but neutral buoyancy means it neither sinks nor floats, giving excellent control.

• Pros: High thrust & speed: two-speed settings up to 4.3 mph. Long low-speed range (45 min) for extended snorkeling. Good depth (50 m/164 ft) and rugged design. Neutral buoyancy aids stability. Bright color and tether enhance safety.
  
• Cons: Heavier (8.2 lb) and bulkier. Pricier (around $599). Single 130 Wh battery is not quick-swap (charged in 1.5–2 h). Only two speeds (no slow crawl mode).

Asiwo Mako Underwater Scooter

The Asiwo Mako is quickly becoming a favorite for kids, families, and poolside fun. It's exceptionally lightweight (around 5-7 lb) with strong positive buoyancy, so it floats if released. Designed for safety, the Mako features two or three gentle speed settings, perfect for easy control and shallow water play. It provides just enough gentle propulsion for splashing, exploring the pool, or assisting with learning to swim. Essential child-safety features include a simple unlock mechanism and often a front action camera mount for capturing fun moments. With its standard battery, expect ample playtime, perhaps 45-60 minutes on low speed, ideal for typical pool sessions. The Mako's intuitive design and robust safety measures (positive buoyancy, child-lock, simple controls) make it an excellent, fun entry-level water scooter for all ages in the pool.

• Pros: Extremely lightweight and easy for kids to handle (e.g., 6.5 lb with standard pack). Gentle speed modes ensure safe and controlled fun for all ages. Strong positive buoyancy and a child-lock make it exceptionally safe for family and pool use. Ideal for shallow water and learning basic water propulsion. Very affordable ($269 retail).
  
• Cons: Very limited thrust – strictly for recreational poolside or shallow water play, not suitable for open water, snorkeling, or diving. Run-time might be shorter on higher speeds, requiring recharges for extended play sessions. Not designed for towing or covering significant distances.

Nautica Navigator Seascooter

The Nautica Navigator is a step up for younger explorers. It runs around 2.5 mph at full throttle, and can dive to 30 ft (10 m). With a 7.5Ah lead-acid battery it also delivers 60 min of runtime. It’s heavier (11.4 lb with battery), but still user-friendly: a contoured handle and single trigger control make it easy for kids to steer. It even has a camera mount for GoPro-style action cams. Like the Marlin, it’s positive-buoyancy and designed for safety (e.g. propeller guards).

• Pros: Faster and deeper than the Marlin. 2.5 mph is respectable for recreational use. Full hour runtime. Includes safety features (camera mount, floatation). $394 price is very reasonable for its performance.
  
• Cons: Still only one speed/gear. Lead-acid battery takes 7–8 h to recharge. Weighs 11+ lbs, which is hefty for a child’s toy (rigid design). Max 10 m depth is good for beginners but far less than dedicated dive scooters.

Waydoo Subnado Underwater Scooter

The Waydoo Subnado is a compact, lightweight DPV (only 6 lb) designed for portability. It’s about the size of a soda bottle and easily fits in carry-on luggage. Despite its size, it can reach speeds up to 1.4 m/s (3.1 mph) and dive to 60 m (197 ft). On a full charge it will run about 56 minutes – impressive for its tiny form factor. The jet-style single propeller is very safe to touch (shrouded and low thrust) so it’s kid-friendly. A unique feature: the Subnado’s battery can also serve as a 100W portable power bank. It recharges in just 1.2 h.

• Pros: Ultra-portable: at 3 kg and 15×2.75×2.75″, it’s airline-friendly (98 Wh battery). Good speed & depth: 3.1 mph and 60 m rating. Long run-time (56 min) and fast 1.2 h recharge. Travel-friendly (fits in a backpack). Solid build (aluminum & foam). Child-safe propeller guard.
  
• Cons: Only a single thrust (less power than dual-motor designs). No variable speeds beyond 3 preset modes. Non-swappable battery (not modular). At $429 it’s pricier than basic kids’ scooters (but still under $600). Lacks a float “nose” – it’s neutrally buoyant so it neither floats nor sinks.
