When assembling your scuba unit, the outlet from the cylinder valve should be pointed toward the diver's head.

• A. Away from the head
• B. Sideways
• C. Toward the diver's head
• D. Downward

Answer: (C)

Focusing on how the cylinder connects to the rest of your gear, orienting the valve outlet toward the diver’s head keeps the regulator hoses positioned to run down along the body rather than across the face or neck. This makes the first stage easier to access, reduces the chance of hoses snagging on clothing or gear as you don the rig, and helps the gas path remain unobstructed during setup and in the water. If the outlet pointed away from the head, hoses could cross the face or neck, kink, or snag more easily, making the assembly less comfortable and more prone to movement problems.
