honestly, its not scary at all... Well, maybe a little.. I got little freaked out on one dive called The Pit.. Its a big "pit" 120 feet deep, but is soon cool.. So, I'm down around 100 feet and my psi gauge on my computer starts going nuts.. its at 1800.. then jumps to 1100.. then jumps to 1400... then back to 1800 - all in 2-3 seconds.. and kept doing it...
I've never in 27 years of diving seen a psi gauge (digital) do that.. freaked me out because, as you know, at 100 feet its gonna take some time to safely come up and then safety stop and I really didn't know how much air was in the tank cuz it kept jumping back and forth.. All was well, but it kind of ruined my favorite cave dive of the trip..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
