Quantum is a completely new BCD by Mares. Based on a standard front adjustable design, it introduces many new ideas, not the least of which is a brand new integrated weight system, and boasts exceptional sturdiness and stability.
Mares listened to its customers and the Quantum is the result of comments received over a long period of time. A new bladder was designed, maintaining high lift capacity while allowing more mobility and freedom of movement by keeping a low profile on the side lobes. The shoulder pads were the object of long experimentation in order to find the sturdiest yet most comfortable geometry, and are specific to each size of the BC. Even the position of the stainless steel D-rings are optimized for ease of use instead of cosmetic appeal. Talking about D-rings, a small technopolymer D-ring was added to the right shoulder at a 45° angle, allowing for the placement of a lanyard to a console, so that the latter hovers in the field of view of the diver when in a swimming position. The sternum closure adjustment is on one side only, that of the corrugated hose. This prevents a loose end of a strap getting in the way of the pull knob of the right shoulder dump valve. On the sternum strap closure buckle we find the new low profile whistle. These are all many small details that add up to great value.
