8 Best Underwater Scooters of 2026

The Sublue Mix delivers a thrilling underwater experience with its dual-motor power and smooth, intuitive ride—making it a standout for snorkelers and beginner divers seeking real propulsion without bulk. With 10kg of thrust and speeds up to 1.5 m/s, this scooter cuts through water effortlessly, turning lazy pool laps into dynamic aquatic adventures. Its 30-minute battery life and removable 11000mAh pack mean you can extend your session with a spare, while the one-button start and propeller guards make it beginner-safe and travel-ready.

In real-world use, the Mix shines in pools and calm coastal snorkeling zones, where its 131ft (40m) depth rating is more than sufficient and the lightweight 7.7lb frame stays manageable even for younger users. The action camera mount captures stable, shake-free footage, and the detachable floater lets you toggle between surface cruising and deeper dives. However, it struggles in strong currents or open ocean conditions—its thrust, while strong, isn’t enough to consistently fight turbulent water. Battery drain accelerates in high-resistance environments, so plan for shorter runs in choppy seas.

Compared to the Asiwo and Nautica Skipper, the Mix strikes a sweet spot between performance and portability, offering dual motors at a fraction of the cost of pro models like the Navbow+. It’s ideal for travelers who want serious underwater mobility without the premium price tag or complexity. While it doesn’t match the battery life of the Mix Pro, it’s lighter and more compact—making it the best dual-motor value for casual adventurers who prioritize ease of use and airline-friendly design over marathon runtime.

The Waydoo Subnado redefines control with its thumb-operated trigger, offering surgical precision that feels more like piloting a futuristic drone than swimming with a scooter. At just 3lbs and measuring under 15 inches, it’s the most compact and portable option in the lineup—perfect for travelers stuffing gear into carry-ons. The aluminum-alloy housing feels rugged, and the 197ft depth rating opens up serious diving potential, while the 14.33 lbs of thrust delivers snappy acceleration for its size.

During testing, the Subnado proved exceptionally agile in tight reef zones and murky lakes, where its thumb controller allowed for micro-adjustments in speed and direction—something trigger-grip models can’t match. The 3-speed gears and cruise mode extend runtime to 56 minutes, and the 100W reverse charging is a game-changer for powering phones or lights mid-trip. However, the small grip can be awkward for adults with large hands during extended use, and the fingertip controller requires some getting used to—especially in cold water with gloves. It’s not ideal for two-handed towing or kids under 10.

When stacked against the Sublue Mix, the Subnado trades raw power for unmatched portability and control finesse, making it the go-to for technical divers and SUP riders who value precision over brute force. It’s less of a tow-behind machine and more of a personal propulsion tool—perfect for underwater photographers or solo explorers who need to hover, pivot, and glide with ease. While it lacks a built-in display like the Navbow+, its accessory-rich ecosystem and device-charging capability give it an edge in versatility and innovation.

The Asiwo Underwater Scooter stands out with its one-hand mode, a clever innovation that lets you wave, point, or interact with marine life while still gliding forward—something no other model offers. Powered by dual 600W motors, it generates 9kg of thrust and reaches speeds up to 3.35 mph, making it more than capable for snorkelers and pool explorers. Its FOC (Field-Oriented Control) tech ensures whisper-quiet operation and buttery-smooth acceleration, while the 35-minute runtime and 40m waterproof rating keep you exploring at depth.

In practice, the self-floating design is a game-changer for beginners and kids, preventing accidental sinkage and reducing panic if dropped. The action camera mount captures immersive first-person footage, and the 3-speed system lets you dial in the perfect pace—from lazy surface drifts to quick bursts toward coral formations. However, the plastic housing, while lightweight, feels less durable than aluminum competitors, and the 2–3 hour charge time lags behind faster-charging models. In strong currents, it shows slight drag, and the thrust, while solid, doesn’t match higher-end dual-motor units.

Compared to the Nautica Skipper, the Asiwo offers better speed, depth, and tech, but at a higher price and with less runtime. It’s the ideal pick for families and eco-tourists who want interactive underwater fun without the bulk. While it doesn’t have the battery life of the Mix Pro or the smart features of the Navbow+, its one-hand freedom makes it uniquely engaging—perfect for those who want to touch, signal, or gesture while moving. It’s not the fastest or longest-lasting, but it’s the most playful in the lineup.

The Nautica Skipper is the most budget-friendly underwater scooter that still delivers real performance, making it the best entry point for families and first-time users who want more than a toy. With a top speed of 2 mph and a 15ft depth limit, it’s designed for pools, shallow snorkeling, and calm lakes—not deep dives or ocean adventures. But what it lacks in depth, it makes up for in runtime, offering a staggering 90 minutes of use on a single charge, the longest in this group.

In real-world testing, the Skipper proved reliable for kids and casual swimmers, with dual triggers that shut off instantly when released—adding a layer of safety that parents will appreciate. The safety grille prevents hair or fabric from getting caught, and the top-mounted camera mount is compatible with most action cams. However, its 7–8 hour recharge time is a major drawback, and the low max depth limits it to surface-level play. The motor is quiet but underpowered in currents, and the build, while sturdy, feels more utilitarian than premium.

When compared to the Hagul or Asiwo, the Skipper trades depth and speed for unbeatable battery life and safety, making it ideal for family pool days, swim lessons, or supervised kids’ use. It’s not built for adventurers, but for those who want affordable, long-lasting fun, it’s unmatched. While the Sublue Mix offers deeper diving and more power, the Skipper delivers three times the runtime at half the price, making it the smartest pick for shallow-water enthusiasts who value endurance over exploration.

The Hagul Underwater Scooter is tailor-made for kids and beginners, with a positive buoyancy design that keeps it afloat—eliminating panic if dropped and making it easy to retrieve. Its one-button start and LED indicator simplify operation, while the 2-speed gears (2.5 mph low, 3.1 mph high) offer enough excitement without being overwhelming. With up to 50 minutes of intermittent use and a 49ft depth rating, it’s perfect for pool play, shallow snorkeling, and supervised sea adventures.

During testing, the lightweight 3.5kg frame was easy for children to handle, and the protective cover kept fingers safe from the propeller—crucial for young users. The airline-compliant battery makes it travel-ready, and the real-time LED display shows speed and battery level clearly. However, the low-speed mode feels sluggish in even mild currents, and the plastic construction, while durable enough for kids, lacks the premium feel of metal-bodied models. It’s not designed for deep dives or adult use, and the lack of camera mount is a missed opportunity for memory-making.

Compared to the Nautica Skipper, the Hagul offers better speed and buoyancy control but no camera support or dual triggers. It’s less of a tool and more of a play device—ideal for children ages 8–14 who want a safe, intuitive way to explore underwater. While it doesn’t match the tech of the Subnado or the power of dual-motor units, its focus on safety and simplicity makes it the best choice for young swimmers. For parents seeking a fun, low-risk introduction to underwater scooters, the Hagul delivers where it matters most.

The Waydoo Subnado (Compact & Portable) model is a traveler’s dream, combining ultra-lightweight design with serious performance in a sleek, airline-approved package. Weighing just 3lbs and packing a 98Wh battery, it slips into carry-ons without hassle—making it the most portable high-performance scooter available. Its thumb control system offers unmatched precision, and the 14.33 lbs of thrust delivers quick bursts of speed, ideal for SUP riders, snorkelers, and underwater photographers who need agility over brute force.

In real use, the Subnado excels in calm bays, reefs, and freshwater lakes, where its 197ft depth rating and cruise mode allow for extended exploration. The fast 1.2-hour charge time and 56-minute max runtime keep downtime minimal, and the reverse charging feature is a standout—letting you power a phone or light from the scooter itself. However, the small form factor means less grip stability for larger users, and the fingertip controller can fatigue hands during long sessions. It’s not built for towing or two-person rides, and the lack of a display means you’re guessing on battery and depth.

Pitted against the Sublue Mix, the Subnado wins on portability and innovation, but loses on towing power and ease of use for beginners. It’s the best compact & portable option for tech-savvy travelers and solo explorers who prioritize control, charging versatility, and airline compliance. While it doesn’t have the smart sensors of the Navbow+, its accessory ecosystem and device-charging ability make it the most future-ready scooter under $400.

The Mix Pro is built for endurance, offering up to 60 minutes of intermittent use—the longest battery life in its class—making it the top pick for divers and snorkelers who hate mid-dive recharges. With dual motors delivering 24lbf of thrust and speeds up to 4.02 mph, it’s powerful enough to tow two adults or power through moderate currents with ease. The removable battery and 2-hour fast charge mean you can swap and go, while the adjustable buoyancy floater lets you dive deep or float high with a simple attachment.

In real conditions, the Mix Pro shines on long reef explorations and open-water swims, where its 30-minute continuous low-speed runtime outlasts most competitors. The LED low-battery alarm prevents surprise shutdowns, and the top-tier sealing ensures reliability at 131ft depths. The camera and smartphone mounts are versatile, and the 7.82lb weight keeps it manageable out of water. However, it’s bulkier than compact models, and the one-button operation, while simple, lacks the fine control of thumb triggers. It’s overkill for pool play but perfect for serious adventurers.

Compared to the Sublue Mix, the Mix Pro offers double the battery life and higher top speed, but at nearly twice the price. Against the Navbow+, it lacks smart sensors and app integration but delivers better value for pure runtime and power. It’s the best long battery life model for divers and adventure seekers who prioritize time in water over tech features. If you want to stay submerged longer without swapping batteries, the Mix Pro is unmatched.

The Sublue Navbow+ is the undisputed king of underwater scooters, earning its title as the best overall with a 31lbf dual-motor punch, OLED smart display, and app-connected navigation that transforms it into a true underwater command center. With speeds up to 4.47 mph (TURBO mode) and a 60-minute intermittent runtime, it delivers pro-level performance for serious divers, photographers, and tech enthusiasts. The micro-positive buoyancy ensures it floats if dropped, and the digital compass, depth sensor, and real-time temperature readout make it as functional as it is fast.

In real-world dives, the Navbow+ excels in open ocean and deep reef environments, where its smart alerts (low battery, over-depth) and return-to-home function via the SublueGo app add a layer of safety unmatched by any other model. The 3-gear system lets you conserve power or unleash speed, and the diving log feature automatically records and shares your journey—perfect for content creators. However, its $1099 price tag is steep, and the 8-minute Turbo runtime means high-speed bursts are brief. It’s overkill for casual swimmers and too advanced for kids.

Stacked against the Mix Pro, the Navbow+ offers superior intelligence and navigation, but at a much higher cost. Compared to the Waydoo Subnado, it’s less portable but infinitely more capable. It’s the best overall for professional divers, underwater filmmakers, and tech-forward explorers who want maximum power, safety, and data tracking. While it doesn’t beat the Nautica Skipper on price or the Hagul on simplicity, it dominates in performance, features, and innovation—making it the ultimate underwater investment.
