If you're looking for a durable, strong and almost bulletproof BCD jacket than the Start is what you are looking for. Constructed from extremely Strong 500 and 1000-Denier Cordura, with excellent buoyancy, even on smaller sizes the Start full jacket BCD fits the bill. Designed with the demanding use of dive training and rental facilities in mind this BCD will give the sport diver years of dependable use.The BCD has three over-pressure relief/dump valves with two located on the left and right shoulders and a third lower valve on the rear right of the air cell. All three can be manually dumped two with pull cords and the other with the power inflator mechanism. There are two plastic D-rings and two additional snap hooks for attachment of instruments and accessories. If used at dive facilities a size indicator is highly visible on the right shoulder. BCD has two large accessory storage pockets with hook and loop closures, and the adjustable sternum straps along with both torso adjustment and waist straps are equipped with "squeeze-style" side-release buckles for easy donning and doffing The waist strap/cummerbund assembly is independently suspended from the air cell allowing the air cell to inflate away from the diver preventing the "squeeze-effect" when inflated. The backpack is rigid for support and stability of the cylinder yet is fully padded for comfort.
