the wonders of Android are just becoming apparent to me. Yes I have loads of apps that I mess around with - but having just used GPS Essentials in the Keys on my phone and locating dive sites etc. I was absolutely amazed. I just ordered the new Evo 3D and I'm thinking, what will protect my phone if it gets wet - find out they have waterproof cases that can go to 100 ft. So I'm thinking, well, that's fantastic - but do they have any kind of app that can work as a depth gauge? So if I'm free diving with my phone, it will tell me how deep I'm going (probably not deeper than 30 feet)? I know there are scuba apps coming out where apparently it will log your dive (at least I think this is the case), but I wouldn't need an app that advanced - right now, just want to see how deep I can free dive to. Or just a depth gauge - or anything scuba related. Anyone? Has anyone used FlytoMap apps? Are they any good?
