The best underwater scooter for snorkelling is usually the one you can actually take with you. Speed and thrust matter, but for most snorkellers the deciding factors are weight, size and one rule most product pages skip: whether the battery is allowed on a plane. This guide walks through what to look for, how airline battery rules work, and where each model in the Waydoo Subnado range fits.
What makes an underwater scooter good for snorkelling
For snorkelling you want a scooter that is light in the hand, easy to control at the surface and compact enough to carry to the beach without a trolley. The Waydoo Subnado weighs 1.4 kg and is 377 mm long, closer to a large water bottle than to the twin-handle dive scooters built for boat dives. With 6.5 kg of thrust from its 500W motor it pulls you along at up to 1.4 m/s, and up to 2.0 m/s if you mount two units together.
Runtime matters more than headline speed. A snorkelling session is long and unhurried, and the Subnado runs for up to 56 minutes on a charge, then recharges in about 1.2 hours over USB-C fast charging. That is a full reef session, a charge over lunch, and a second session in the afternoon.
The airline battery rule that decides your travel scooter
Airlines generally allow lithium batteries under 100Wh in carry-on luggage without prior approval. Between 100Wh and 160Wh, most carriers require you to ask the airline in advance, and above 160Wh the battery does not fly on a passenger aircraft at all. Batteries belong in the cabin, not in checked baggage.
This is why the Subnado's 98Wh battery is the single most travel-relevant number on its spec sheet. It sits just under the universal carry-on threshold, so the scooter that swims with you in the Red Sea in October can fly home in your hand luggage. The more powerful Subnado Plus carries a 144Wh battery, which flies with most carriers only after airline approval, so it suits divers who mostly drive to the water. Always confirm the current rules with your carrier before you fly.
The Subnado range compared
| Model | Motor and thrust | Battery | Flies carry-on? | Price incl. VAT |
|---|---|---|---|---|
| Subnado Standard | 500W, 6.5 kg thrust | 98Wh, up to 56 min | Yes, under the 100Wh threshold | 499 euro |
| Subnado Plus | 800W, 9.3 kg thrust | 144Wh, PD3.1 140W charging | Usually with airline approval | 799 euro |
| Subnado Lite | Compact travel model | Smaller pack for short sessions | Yes | From 399 euro |
For most snorkellers and travelling divers, the Subnado Standard at 499 euro is the balanced pick: full runtime, airline-safe battery, and enough thrust for adults in open water. The Subnado Plus at 799 euro adds 800W and 9.3 kg of thrust for divers who want more pull, and the Subnado Lite from 399 euro is the lightest way in for holidays and pool use.
Depth, build and safety
Snorkelling happens in the top few metres, but a scooter should be built for more. The Subnado is IP68 rated to a maximum operating depth of 60 metres, which means the same unit covers snorkelling, freediving and scuba without you ever working near its limit. The wrap-around guard encloses the propeller, and a leash keeps the scooter with you at the surface. If you are new to sea scooters, our underwater sea scooter guide covers how they work and how to use one safely.
Charging on the road
Travel gear should charge from travel chargers. The Subnado charges over USB-C, the same port as your laptop and phone, with PD3.0 100W fast charging bringing an empty battery back in about 1.2 hours. There is no proprietary brick to pack and no mains-only charger tying you to a hotel room; the Plus goes a step further with PD3.1 140W support.
Who a sea scooter is not for
A sea scooter is for exploring beneath the surface. If what actually appeals is moving fast across the top of the water, you are shopping in the wrong category: that is an eFoil, and our guide to what an eFoil is and how it works is the place to start. For everyone whose holiday photos happen underwater, the Subnado is the tool for the job, from EU stock with a 2-year warranty and delivery without customs surprises.
