Next time you do practice this skill, evaluate how it easy it was. If you had any problems, consider buying Oceanic's Swivel 180 Degree Octopus-it's super simple to use. As its name implies, the Swivel 180 Degree octopus has a swivel where the low pressure hose attaches to the second stage. But that'snot its only unique feature. Unlike most second stages, the 180 octopus has no up or down and exhausts exhaled bubbles at the side.

To make it easy to find, the Swivel 180 Degree octopus and its hose are high visibility yellow. To avoid jaw fatigue, the second stage weighs only 5.8 ounces and features an anatomically designed mouthpiece. The Swivel octopus cover, which has an integrated purge valve, measures only three inches across, so this second stage is compact and low profile.
