Helicopter Aircrew Breathing Device

The Helicopter Aircrew Breathing Device or HABD (also known as a HEED or SEA) is a piece of military survival gear which was adopted in order to increase the chances of survival for embarked troops and aircrew trapped in an aircraft which has ditched (crashed into a body of water.) Similar in function to SCUBA gear, it consists of a small cylinder pressurized with atmospheric air and first stage regulator worn in a pouch on the user's life vest; a pressure gauge; an air hose and a special second-stage regulator (the part that delivers air via the user's mouth). ^[1]
