Tyger-Ray is an electric underwater scooter designed for use during snorkelling or diving that not only increases dive time by saving energy, and therefore oxygen, but also lets you throw underwater loops and somersaults to depths of up to 38 metres. Travelling at 4 kph above and below the surface when used by an average-sized person, the rechargeable 12 volt system delivers a run-time of more than 60 minutes under typical conditions.

Tyger-Ray is an electric underwater scooter designed for use during snorkelling or diving that not only increases dive time by saving energy, and therefore oxygen, but also lets you throw underwater loops and somersaults to depths of up to 38 metres. Travelling at 4 kph above and below the surface when used by an average-sized person, the rechargeable 12 volt system delivers a run-time of more than 60 minutes under typical conditions.

Tyger Ray is constructed from impact proof, UV resistant and highly visible polyethylene and the placement of motor and propeller is underneath and in front of the diver to maximise water flow, thrust and manoeuvrability whilst minimising any chance of dive gear or hair becoming entangled.

Operation of the underwater scooter is via a magnetic safety switch and glove that engages the single speed drive and ensures that it stops when you let go.The benefits to dive duration come from the fact that you dont have to rely on kicking to the same degree, so you burn less energy and use less of the oxygen in your tank.

The maintenance-free 12 volt battery takes 8-12 hours for a full recharge, the unit weighs just 22kgs and another attractive feature of the Tyger Ray is the price - AUS$1,500.

Tyger Ray is the latest aquatic accessory from the Australian company that developed 12 volt diving systems, PowerDive International.
