The Dive Xtras 3-Point Tow Harness is designed to move thrust loads away from the arms and into the hips. This makes long-duration scootering significantly more comfortable. The strap also performs the same duty as a normal crotch strap and prevents your equipment moving excessively. The Harness is constructed of { 2 in | 5.1 cm } webbing around the waist and { 1.5 in | 3.8 cm } webbing for the leg loops. A { 2 in | 5.1 cm } standard D-ring provides the attachment point. The waist buckle is a { 2 in | 5.1 cm } plastic slide-release and two { 1.5 in | 3.8 cm } slide-release buckles are on each leg loop.

To use a Dive Xtras scooter correctly, you must have a tow harness to provide an attachment point for the scooter's tow cord. 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 2-inch webbing between the legs. This works fine for preventing your equipment from moving around, however it can be uncomfortable when used as an attachment point for a high-performance scooter.

This strap can also be used for people whose diving equipment does not come with a crotch strap. If your equipment has a 2-inch waist strap, it can be fitted directly. If not, it can be used with a waist strap similar to a weight belt.
