Excavation time is by far the biggest contributing factor in avalanche fatalities. By reducing or eliminating burial depth you substantially increase your chances of survival. The Float 30 uses a small cylinder of dry compressed air, a single–chamber 150–liter airbag, and a venturi system to reduce cost and weight. The airbag itself not only helps prevent burial, but protects the head, neck and upper body from trauma. With its location behind the head and away from the hips and arms, it preserves the user’s peripheral vision and his or her ability to escape the avalanche before it picks up speed.
