Best Underwater Scooter 2021

WINDEK SUBLUE Seabow Smart Underwater Scooter

Can you take a scooter underwater? Probably once! However these ones are specially designed underwater Scooter for increasing your speed while diving or snorkeling and minimize your effort.

A word in advance: These are not professional underwater scooters to go into caves and do technical diving with.
The ones here for example are for getting to a far away dive site quicker or explore a long distance wall or a new dive site use them in the pool for your kids or for snorkeling.

An underwater scooter has several moving parts

There is the Speed or throttle button, the propeller itself sometimes there are camera mounts which are adjustable, all need to be taken care of especially after use in saltwater. which means they have to be cleaned thoroughly with fresh water afterwards.

Price range

The prices range from as low as 300,- to 1500,- US$ depending on the of the material, built quality, Battery, size and durability.

Speed of an underwater scooter

They are ranging from around 2mph (3.2km/h) to 4.5mph (7.2km/h)

Maximum ascent rate limit while scuba diving

In Diving you are required to not exceed your maximum ascent rate limit which is depending on your organization you learned with. Some are as low as 30ft/min (10m/min) some are as high as 59ft/min (18m/min). However the slower the better now if you do a Scuba Dive and at any time of your dive point your Scooter upwards and press the highest setting throttle power button which in some underwater scooters can run up to 4.5mph (7km/h) speed, that converted you’d ascent with a rate of 380ft/min (116m/min) that for sure will seriously harm you and a Decompression sickness is imminent!!!

So we recommend to only use the underwater scooter on a straight depth line or downwards but here too not exceeding your depth limit depending on your level of certification!!! For most it is 30m or 100ft.

Freediving and Snorkeling with an underwater scooter

In case of freediving which means you take a breath on the surface and then dive while holding your breath the ascent rate does not matter because you don’t saturate enough with nitrogen during a freedive to get a decompression sickness.

However also here you need to be careful! You need to be able to come back up to the surface safely without having a shallow water blackout due to too long of a breath hold.

Always best to follow the rules and dive with a buddy as always in water sports!

Depth limit

The depth limit depends on the model it ranges between 30 to 130ft (10-40m)

Buoyancy of an underwater scooter

Most of them are slightly positive buoyant so if you loose them underwater they’ll come back up to the surface and you can’t loose them. Another possibility would be to secure them with a double clip hook and a bit of string.


Size depends very much on the Battery and the design of the Product it ranges from around
W 10” x H 6” x L 19” / W 270 x H 140 x L 500 (mm)
to around
W 12.6” x H 11.8” x L 24” / W 320 x H 300 x L 610 (mm)


Weight also depends very much on the used Battery as it is the heaviest part of the whole.
Ranges are around 6 pounds (2.7 Kg) to 22 pounds (9.5 Kg) including the Battery

Camera assembly

Many of the later models have a camera assembly mount where you can attach a GoPro or Action Camera to it So you don’t miss out on any big Fish swimming by. Compatible with multiple action cameras so that underwater photographic equipment is no longer a burden, freeing you to record more memories, capturing your wonderful underwater moments, providing an integrated POV filming experience Often possible to mount it backwards for the intriguing video selfie of you having fun underwater.


The Batteries nowadays are mostly Lithium ion batteries the same as in your mobile phones.

Lithium ion battery advantages:

  • higher energy density,
  • voltage capacity and
  • lower self-discharge rate
  • Non memory effect
  • Quick charging

Lithium ion battery disadvantages:

  • Expensive
  • Protection required
  • Aging effect
  • Transportation problems
  • Deep discharge
  • Safety concerns
  • Sensitivity to high temperature

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles whichever comes first.

Some Underwater Scooter still come with a sealed Lead Acid Battery.

Run Time & Speed

The actual working time and speed of an underwater scooter depends on the capacity and size of the battery, the set speed setting, water currents, the water resistance of you and your equipment and the person who operates it. Adults get out less working time compared to children because the underwater scooter has to work harder to pull a 75 kg person compared to a 30 kg child.

Most of them have a run time between 30-60min

External or internal charging

Both possibilities of internal and external charging are on the market whatever you prefer you choose.

Charging time

Depends on the size of the Battery and the Ampere of your charger.

Commercial Airplane transport

Some Li-ion Batteries are too big and are not allowed to carry in commercial airplanes so be careful and read the limitations of the airline.
