Sierra Series
2005 - 2014

The Sierra X-Scooters are all modular so that you can interchange bodies to create the scooter for your specific diving needs. Many owners use the standard body and 2 batteries for general diving doing 2 dives a day, but also own the long body into which they can place the same 2 batteries for longer more technical dives. Either body can be balanced in fresh and saltwater via the integrated weighting system. The Sierra family uses the latest technology with a powerful brushless motor, NiMh batteries and electronic speed control. Trigger Shift on the Fly allows the user to select any one of 5 speeds with a simple click of the trigger.
