An underwater sea scooter, sometimes called a dive scooter or a diver propulsion vehicle, does one simple thing: it pulls you through the water so you use less energy and cover more distance. Here is how they work, the specs that actually matter, and how to choose across the Waydoo Subnado range.
What an underwater sea scooter is
A sea scooter is a compact, battery powered unit with an electric motor and a propeller inside a protective housing. You hold on, squeeze the control, and it tows you forward underwater. Divers and snorkelers use them to explore more of a site, to reduce effort against currents, and to make a single breath or a single tank go further.
How it works
Inside the housing, the motor turns a propeller that moves water backward and pushes you forward. A finger ring or thumb control sets the power, and a cruise mode lets you hold a steady pace hands free. A propeller guard keeps fingers away from the moving parts. Because the unit does the work, your legs and lungs do less, which is what extends your time and range underwater.
The specs that matter
Four numbers are worth comparing. Speed, measured here up to 1.4 metres per second with a single unit and 2 metres per second when two are paired. Depth rating, which on the Subnado is a maximum operating depth of 60 metres. Battery, a 98Wh lithium pack that is within common airline limits and fast charges in about 1.2 hours over 100W USB-C. And weight, around 1.4kg for the compact main unit, so it fits in hand luggage.
Practical details matter too: a quick release mount lets you attach the scooter to an arm, a leg, a board or a tank, and reverse charging means the battery can top up a phone or a light between dives.
Choosing across the Subnado range
The Subnado Lite is the entry model at 399 euro, weighs around 3 lbs, runs three speeds plus cruise for about 50 minutes and is built for travel and easy first use. The Subnado Plus, at 799 euro, steps up to an 800W motor, up to 60 minutes of runtime and faster charging, with the option to pair two units for more pull. Both share the compact, airline friendly design.
Who it is for
A sea scooter suits divers and snorkelers who want to see more of a site, move comfortably against mild currents, or bring less physical effort to a relaxed underwater session. It is not a substitute for dive training or a buoyancy device, and it is a different product from an eFoil, which flies above the water rather than travelling beneath it. If it is flight above the surface you are after, look at the Waydoo Flyer EVO instead.
