Subnado Underwater Scooter: Revolutionizing Your Aquatic Adventures

The Waydoo Subnado Standard is an unusually compact underwater scooter built for snorkeling, recreational diving, swimming, and compatible board attachments. Its strongest advantages are portability, USB-C charging, and a 98Wh battery designed with air travel in mind. Its limitations include a short high-power boost, runtime that changes with speed and conditions, and a premium price for occasional pool use.

This does not affect our evaluation. We have not personally tested this unit; this review is based on manufacturer specifications, documentation and product research.

Unlike a full-size diver propulsion vehicle, the Subnado uses a narrow cylindrical body that can be held in one hand or attached through optional mounting accessories. It is easier to pack than many conventional sea scooters, but its compact size does not remove the need for proper water skills, supervision, and dive planning.

These are manufacturer specifications for the Subnado Standard. Speed and runtime can change with rider size, drag, current, water temperature, selected mode and accessories. A maximum figure should be treated as a best-case rating rather than a guarantee for every outing.

What the Subnado is designed to do

An underwater scooter uses an enclosed propeller to pull or push a swimmer through the water. It can reduce the amount of kicking needed during recreational exploration and help a capable user cover more distance. The Subnado’s compact format makes it especially relevant for travelers, snorkelers and divers who do not want to transport a bulky traditional DPV.

That does not make it a substitute for swimming ability, scuba certification, a dive buddy or proper gas management. Added speed can increase separation risk, shorten the time available to react and encourage a user to travel farther from the exit point than expected. Its role is propulsion—not flotation or rescue.

Compact design and portability

At about 1.4 kg and 377 mm long, the Standard is small enough to fit into many travel bags. The narrow shape is easier to store than wide dual-handle scooters, and the integrated battery avoids carrying a separate power module.

Portability does involve tradeoffs. A small body offers less room for battery capacity than a larger DPV, and controlling thrust from a compact cylinder can feel different from using two fixed handles. Buyers should also check which mounts and controllers are included in the exact package. “Subnado Standard,” “Subnado Lite,” accessory kits and retailer bundles may not contain the same parts.

Speed, thrust and control

Waydoo rates a single Standard unit for speeds up to 1.4 meters per second, or roughly 3.1 mph. That is enough to create a noticeable pull underwater without putting it in the same category as large technical-diving scooters. A dual-unit configuration can be faster, but it adds cost, weight, charging needs and setup complexity.

The three selectable modes let users balance speed against battery consumption. Super Gear is the short maximum-output mode and is time-limited; it should not be confused with a continuous cruising setting. For most casual snorkeling, the lower modes may provide better control and longer useful runtime.

The finger-ring controller can support one-handed operation, while compatible quick-release mounts allow other configurations. Any wearable or hands-free arrangement deserves cautious practice in controlled water. A user should be able to release power immediately, separate from the unit if needed and avoid loose straps or equipment near the propeller guard.

Battery life and USB-C charging

Waydoo lists a maximum runtime of 56 minutes for the Standard. That figure does not mean 56 minutes at maximum thrust. Higher speed, frequent acceleration, strong current, a larger rider and extra drag can all reduce operating time. Plan the outing around the remaining battery indicator and return with a reserve rather than trying to extract the final minute.

The 100W USB-C PD charging system is more convenient than a proprietary low-power adapter, but fast charging requires a compatible USB Power Delivery charger and cable. Waydoo lists an approximately 1.2-hour charge time under suitable conditions. A lower-output phone charger may work more slowly or may not deliver the intended charging performance.

Allow the scooter to cool and dry as directed before charging. Inspect the charging area and seals for sand, salt, hair or other contamination. Never connect power when the port or connector is wet, and stop using a battery that is swollen, damaged, leaking or unusually hot.

Can you fly with a Subnado?

The Standard’s battery is rated at 98Wh, below the common 100Wh threshold for spare lithium-ion batteries carried by passengers. Waydoo markets the model as airline-friendly, but that description is not universal permission. Airline rules, security procedures, terminal protection and whether the battery can be removed or isolated all matter.

Check directly with the operating airline before travel and review the current rules for lithium batteries and powered sporting equipment. Do not place a loose lithium battery in checked baggage. Protect terminals from short circuits and carry documentation showing the watt-hour rating. International connections may introduce additional carrier or national requirements.

Depth rating does not equal user qualification

The manufacturer rates the Subnado Standard to IP68 and a maximum depth of 60 meters. That rating describes the equipment under specified conditions; it is not a recommendation that a user descend to 60 meters. Such a depth is far beyond recreational open-water limits and requires specialized training, planning and equipment.

Snorkelers should remain within their abilities and local rules. Scuba divers should account for how powered travel affects navigation, buddy spacing, gas consumption and the distance required to return without propulsion. Never use speed or the scooter’s depth rating to extend a dive beyond training or the dive plan.

Mounting an action camera

Compatible mounts can turn the scooter into a useful platform for underwater footage, but the camera and its housing must have an adequate depth rating of their own. A waterproof scooter does not protect an attached camera. Test every mount in shallow water, use an appropriate tether and confirm that the camera does not interfere with the trigger, intake or release system.

If recording is part of the plan, our DJI Osmo Action 3 overview explains the camera’s video and waterproofing features. Always verify the camera’s current housing requirements before taking it deeper than its bare-camera rating.

Care after saltwater and pool use

1. Turn the unit off and follow the manual before removing accessories.
2. Rinse the scooter and approved accessories thoroughly with fresh water after saltwater or chlorinated-water use.
3. Check the propeller guard, intake area, seals and mounting points for line, hair, sand or debris.
4. Let the unit dry completely in a shaded, ventilated area before charging or storage.
5. Store it away from extreme heat, direct sun and freezing conditions, following the manufacturer’s battery guidance.

Do not run the propeller near fingers, hair, loose straps, fishing line or marine life. Follow local rules protecting swimmers, reefs and wildlife, and avoid operating in congested swim areas.

Water-protection ratings also vary widely between products. For comparison, our Shokz OpenMove review explains why an IP55 rating can handle sweat and light rain but does not make headphones safe for swimming or submersion.

Who the Subnado Standard suits

• Traveling snorkelers who value compact gear and will confirm airline requirements.
• Certified recreational divers who understand DPV procedures and want a small propulsion option.
• Pool and open-water users who want powered movement for recreation in permitted areas.
• Action-camera users who want compatible mounting possibilities in addition to handheld propulsion.
• Paddle-board users considering the purpose-built SUP attachment package.

Who should consider something else

• Anyone expecting a flotation or rescue device.
• Technical divers who require long continuous runtime, redundant planning or a conventional tow-behind DPV.
• Occasional pool users who would not benefit enough to justify the price.
• Children using it without close, competent adult supervision and permission from the pool or site.
• Travelers unwilling to confirm battery rules with each airline.

Subnado Standard pros and cons

Subnado Lite, Standard or Plus?

Waydoo’s current lineup includes multiple versions. The Lite and Standard share a compact 1.4 kg form and 98Wh battery, while the Standard lists a longer Super Gear allowance and is positioned as the more versatile all-around package. The larger Plus raises motor output, thrust, speed and battery capacity, but its 144Wh battery may require airline approval.

Confirm the exact model and included accessories on the retailer page before ordering. Product titles, color choices and bundle photos can look similar even when the controller, mounts or charger differ.

Frequently asked questions

How fast is the Subnado Standard?

Waydoo lists a maximum of 1.4 m/s for one Standard unit and up to 2.0 m/s in a dual-unit setup. Actual speed depends on the rider, equipment, water and selected mode.

How long does its battery last?

The manufacturer lists up to 56 minutes, but that is not continuous maximum-power runtime. Higher speeds, current, temperature, drag and rider size affect the result.

Can children use a Subnado?

Suitability depends on the child, local rules and the current manufacturer instructions. Powered water equipment should never replace swimming skills or direct adult supervision. Begin only in controlled shallow water where use is permitted.

Can the Subnado be used in saltwater?

It is marketed for ocean use, but salt and sand require careful post-use rinsing and inspection. Follow the manual’s cleaning, sealing and charging procedures.

Is the Subnado a flotation device?

No. It is a propulsion device and should not be relied upon for flotation, rescue or returning to shore. Users need an independent safety plan appropriate to the activity.

Final verdict

The Subnado Standard’s appeal comes from fitting meaningful underwater propulsion into a small, travel-oriented body. The 1.4 m/s maximum rating, three modes, compatible mounts and USB-C charging make it a flexible recreational option for the right user.

It is not automatically the best choice for every swimmer or diver. Buyers should weigh actual runtime, included accessories, local operating rules, airline requirements and their own water skills. For frequent travelers and trained users who place portability ahead of full-size DPV endurance, the design has a clear advantage. For rare pool use or demanding technical dives, a less expensive toy or a purpose-built professional scooter may be a better fit.
