The "right" Wing

After selecting your harness, your next choice will be the aircell, often called a "wing" because of how it appears on the back of the diver. Frankly, a very common error when selecting a wing is to choose a size much too big, causing a 'taco effect' that makes managing buoyancy considerably more difficult. The cylinder size, type and configuration, not lift capacity, is the best guide to selecting the correct wing.
