Poseidon (Extreme) Omniswivel

I own one and am buying a second. Benefits: 1. Allows the use of non-Poseidon hoses (easy field replacement when Poseidon hoses are not available). 2. Increases comfort and reduces jaw fatigue when used on a long hose (it allows easy adjustment of the 2nd stage position). 3. Allows safe and streamlined underarm routing for use on a necklace-mounted primary 2nd stage or recreational short hose. The swivel is neither too lose nor too tight. It holds the adjustment well. I found the whole unit including the swivel to be very well made and well worth the cost. This is a highly recommended convenience for Poseidon regulator users.

A must-have for any Poseidon user.
