Designed for Scootering
A lot of technical divers using a back plate system have a crotch strap, however the common design of these is a single piece of 2in webbing between the legs. This works fine for preventing your equipment from moving around, however it can be uncomfortable when used as an attachment for a scooter with the thrust of the CUDA.
Make Scootering More Comfortable
This strap can also be used for people whose diving equipment does not come with a crotch strap. If your equipment has a 2” waist strap it can fitted directly, If not it can be used with a waist strap similar to a weight belt.
