AIR SHARING WITH THE SS1
Since the SS1 breathes as easily as a primary, there is one important difference in air sharing with an SS1 over a standard octopus. The diver switches from their primary to breathing from the SS1, then offers the primary to their buddy. This is for two important reasons. Since the SS1 is attached to the shorter BC hose, it will not easily reach the out-of-air diver. And the SS1 diver can also keep buoyancy control and maintain control of the situation.
