Adding Weight Pocket(s) to the BCD cylinder cam band can prevent excess cylinder buoyancy. By placing hard or soft lead in the weight pocket situated on your cylinder, the cam band will keep the cylinder from floating towards the end of a dive and can provide balance to the system for a more comfortable dive. It will also take some weight off the hips when diving with a weight belt. Pockets are made from durable nylon material with a zippered closure for security of weight.
