DIVE ALERT POWER WHISTLE DB1

Easy power inflator connection for long distance audible signaling.  This is a must have safety device in locations like Galapago, Cocos and Socorro.  This signaling device can be heard on the boat much better than a traditional mouth activated whistle and so much better than shouting.  It connects and disconnects just like yoru bcd inflator hose.  Choose this one, and then we will confirm what bcd and reguator system you have to ensure proper connection.
