Objective:Share gas with your buddy while ascending safely to the surface.

Value: In the unlikely event that you run out of gas, you can safely share gas with your buddy and make a safe ascent together to the surface.

How It’s Done:

  1. Make sure you are familiar with your buddy’s equipment.
    1. Signal to your buddy that you are out of air.
    2. Retrieve your buddy’s primary regulator from him or her. Long-hose divers need to remove the long hose from around the neck.
    3. Orient, clear, and breathe from your buddy’s regulator.
    4. Remember to blow bubbles when the regulator is out of your mouth. Meanwhile, your buddy will locate, secure, clear, and breathe from his or her AAS. Divers using a long hose must free up the entire hose length.
    5. Once you are comfortably breathing, establish contact with your buddy and signal to begin ascending to the surface. Your buddy must check his or her SPG with an emphasis on the remaining gas supply and depth.
    6. Signal when you are OK.
    7. Begin the ascent maintaining contact.
    8. Once on the surface, the out-of-gas diver must orally inflate his or her BCD to achieve positive buoyancy.
  2. You will have a chance to act as both a receiver and a donor. Remember that the donor must keep a careful watch on the gas supply.
