Using a modular design and off-the-shelf battery components, the DiveX Piranha P3 Diving Scooter combines lightweight convenience with outstanding speed. It's powered by a series of neutrally buoyant battery packs that are themselves made up of DCB-style lithium-ion batteries meant for power tools — four in each pack. This, combined with the all-new propeller, means speeds of up to 233ft/min, a runtime of up to 450 minutes, and a weight of just 41 lbs. It's rated for use down to 600 feet, can be charged with a regular power tool charger, and is also approved for air travel. Designed and assembled in the USA.
