Developed from the need to equip US Navy helicopter pilots with a small, handheld breathing device, the HEED line has been manufactured since 1979. The HP-4500 model combines a 2.9 cu ft carbon-fiber cylinder rated to 4,500 psi with a separate second-stage regulator and a standard 20-inch flexible braided hose. Applications described by the manufacturer include helicopters, fixed-wing aircraft, float planes, watercraft and vehicles operating around possible water emergencies. Submersible Systems describes HEED 3 as having the smallest footprint in the EBS market.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMade in USA · Since 1979\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eWhat's included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHEED 3 HP-4500 breathing device and cylinder\u003c\/li\u003e\n\u003cli\u003eIncluded holster with mouthpiece cover and MOLLE-compatible attachment\u003c\/li\u003e\n\u003cli\u003eDial-gauge pressure indicator\u003c\/li\u003e\n\u003cli\u003e20-inch flexible braided hose, two-stage breathing device and on\/off knob\u003c\/li\u003e\n\u003cli\u003eOne refill adapter per HEED unit only if selected above\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNose clip, compressor, filling tank, life vest and PFD are sold separately.\u003c\/p\u003e\u003ch2\u003eRefilling your HEED\u003c\/h2\u003e\u003cp\u003eOptional 920CS stainless-steel air-compressor refill adapter (+$65).
