Wide-bodied shoulder pads further distribute weight. Oversized parachute-style harness fasteners adjust smoothly, even when wearing gloves. Reflective front patches enhance night visibility. Enhanced latching system with durable fabric band makes cylinder changes quick and efficient. 2 interconnected pressure reducers provide an automatic transfer to the secondary circuit and vibrating alarm, triggered by reduced primary pressure. The control console has an Auto-On edge-lit pressure gauge light. Simplified central battery module holds six AA batteries.
