Underwater scooters

There are now several companies making underwater scooters, so in order for one of the things to stand out, it really has to be special. The Subnado aims to be just that, claiming the title of the world's smallest and lightest underwater scooter.

In recent years, we've heard about electric surfboards, bodyboards, hydrofoil boards and underwater scooters. Buying all of those separately could get pretty expensive, which is why the mo-jet system combines them in one modular setup.

A couple of years ago, LeFeet announced its S1 modular electric underwater scooter. The Chinese manufacturer is now back again, with the less expensive C1 model – and it can do more than just scoot underwater.

When it comes to underwater scooters, there are smaller, less powerful single-motor models, or larger, faster dual-motor units. The new WhiteShark Tini, however, can be used in either configuration.

It was two years ago that we first heard about the Trident, an underwater scooter made by Chinese startup Geneinno. The company has now released a cheaper, more portable model, known as the Geneinno S2.

Back in 2017, Chinese startup Sublue successfully crowdfunded an underwater scooter known as the WhiteShark Mix. The company is now set to release a new-and-improved model, called the Mix Pro.

Although we've seen a number of personal underwater propulsion devices in recent years, the Scubajet was one of the first. Its designers have now announced a Pro model, that reportedly dives deeper, runs longer, and features a dual-hand controller.

​We've seen mermaid-type monofins before, and we've also seen so-called underwater scooters. A group of US/UK entrepreneurs has gone and combined the two, in the form of a monofin that gives swimmers an electric boost with each kick.

Now on Kickstarter, the MagicJet underwater scooter can propel divers, snorkelers and swimmers through the water with its onboard motor, and features an interesting modular design should they want to double the thrust.

​A couple of years ago, Chinese startup Sublue Tech successfully crowdfunded its WhiteShark MIX underwater scooter. Now, the company is back with the faster and longer-running Seabow.

​Last year, Robosea successfully crowdfunded its fish-like BIKI underwater drone. Now, it's testing the waters again (no pun intended) with the SeaFlyer underwater scooter. Whereas BIKI was designed for remotely exploring the depths, the SeaFlyer is for people who actually want to get wet.

​So-called "underwater scooters" have become a big thing on crowdfunding platforms, with recent examples including the Trident, WhiteShark MIX and AquaJet H2. One of the latest, the LeFeet S1, features a clever modular design.
