The Dimension is a back-inflation style BC that incorporates Aqualung's integrated Wrapture Harness System, providing amazing comfort and stability. The Dimension is made from durable, fade-resistant ResisteK material and features the patented SureLock II mechanical integrated weight system. Wrapture Harness System f Using patented swivel shoulder buckles and a proprietary, ultra-thin back plate, the Wrapture prevents the BC from "riding-up" on the surface. Out of the water, the Wrapture keeps the cylinder close to your center of gravity and transfers the weight to your hips allowing you to effortlessly stand up straight. SureLock II Mechanical Weight Release System (patented) f allows you to easily insert the weight pouch and an audible "click" lets you know the weights are secure in the BC. Once engaged, the weights can be released with a firm pull the handle. High pressure (HP) hose routings through the back keep your entire kit low profile thus minimizing drag. The low-profile flat valves reduce drag when moving through the water. A bladder retraction system is used to pull in the sides of the bladder during deflation. This keeps unit streamlined and reduces drag. Adjustable chest strap for personal comfort. A clever octo-pocket on the right lobe secures the octopus while keeping it accessible and visible throughout the dive. Two large, easy-to-access utility pockets are found on either side of the Dimension. Easy-to-access knife attachment points on the left lobe accommodate many of the Aqualung knives. Features 4 stainless-steel D-rings and 4 plastic D-rings (1 is located inside the left pocket) for all your accessories. Right shoulder pull dump provides an additional dumping option. Rolled neoprene neck collar for comfort. Non-releasable weight pockets on the back of the BC help the diver achieve proper positioning in the water. All sizes can hold up to 30 lbs. (13.5 kg) of lead weight with 20 lbs. (9 kg) releasable. Buoyancy control is provided by the Powerline inflator mechanism. Powerline is the time-proven airway that has been powering Aqualung BCs over the years. From its over-molded lower unit and stylish hose to its cable activated rapid exhaust, what's not to like? Increased fill rate; now one of the highest air flows in the industry. Environmentally sealed unit for less maintenance. Integrated hose clips attach to the hose to lower profile and streamline gear. Cable activated rapid exhaust at the top, simply pull down on lower unit to dump air. Inflator includes dust cap cover for QD nipple. Inflator comes with a 3/8" threaded low pressure QD hose. BC provides 29 lbs. to 42 lbs. (13.2 kg to 19 kg) of lift. BC comes with an owner's manual.
