Can a Soda-Bottle-Sized Scooter Power You Through the Sea?

Most underwater mobility devices are large, hands-on machines designed for diving professionals. Recent innovations, however, aim to bring propulsion to casual users and travelers.

Among them is the Subnado, a compact scooter about the size of a water bottle, built for short-distance, powered underwater movement. Its size and modular features reflect a broader shift toward lighter, more user-adaptable marine tech.

What It Is and How It Works

The Subnado uses an internal propeller to generate thrust, helping swimmers or divers move forward with less physical effort. It offers three speed settings and can operate for nearly an hour on a full charge.

A fast-charging battery system and a universal mount enable it to be worn or attached to gear. Some models also offer USB ports for powering small electronics. While its propulsion is modest compared to full-scale scooters, it’s designed for personal recreation rather than industrial use.

Context and Use Cases

This type of device is generally used for surface snorkeling, light diving, or supplemental propulsion during underwater filming. Its portability allows it to be packed into carry-on luggage, which may appeal to travelers heading to coastal or reef destinations. However, it’s not a substitute for traditional dive propulsion vehicles in deep or technical diving environments.
