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