Steel tanks will tend to remain negative throughout the dive even as gas is used
from them. However if using Aluminium 80cuft Side-Mount tanks a second attach-
ment point further forward is necessary to adjust tank trim as gas is breathed from
the tanks and they get lighter and become more buoyant.
When the bottom of the tanks start to float up clipping them forward keeps them
horizontal along the sides of the divers body thus reducing profile and drag.
The first D ring should be positioned behind the hip with the second d ring posi-
tioned half way between this and the center line of the body.
The Low Profile D Rings are ideal for use in warm and cold water using either
Aluminium or Steel Side-Mount tanks.
