my scubapro alarms on low air! how do i know? during night dive off old kona airport once again got completely wrapped up with taking pics of mantas posted above. that was unreal. out of nowhere 2 show up and start feeding and doing their ballet. well i was under the spell blasting my strobes and got low on air. audible went off and i motioned to my dive master i was going up. youd be amazed at how much air you use moving around at 30-45 feet taking pics and trying to avoid others strobes. anyway on my way up noticed 2 huge hulls. it was the kona aggressor. the liveaboard that cruises the big island in mega STYLE. popped up in the middle of the twin hulls and here they are having a bar-b-que sitting in lounge chairs drinking/partying. was kinda cool, said excuse me may i play thru, and submerged and swam over to our boat. was never in danger(plus i always carry spare air) but my wrist computer did give me ample warning to safely surface. does calc i think for your depth and for your remaining air before going audible on you. it does way more functions than my pea brain can think of. but im happy with it and it does what its supposed to and audibles ARE LOUD AND CLEAR!
