We should be planning our minimum bottom gas with a realistic idea of how much we would use to complete an air sharing ascent from our deepest depth Most spgs lose their accuracy under 500psi from slop in the mechanism inside, so even if your min gas comes in below 500 it’s prudent to begin...

Don’t have your ditchable weight make you positive Only ditch enough to make you able to swim up

You guys are way overthinking this If the wing fails at depth and your suit crush makes it impossible to swim up, wear ditchable weight so you can swim to the surface

alot of people who dive the caves in Florida in HP130s need no lead the drysuit provides the redundant buoyancy needed in the event of a wing failure

The best way to find out how much weight you need is to get in at the beach in your full setup with a weight bag full of 1 or 2 lb weights and your tanks around 500psi get to 10-15 feet of water, empty your bc completely and start dropping weights 1 or 2 lbs at a time. while motionless if you...

Or call the dive and try again with someone new the next day I've done a decent amount of cave dives with instabuddies I got from an instructor's contact list and haven't had a dud yet Not saying its not going to happen but I'd be willing to bet the number of qualified/good people on your...

Part of what you learn in a GUE course is that, alongside your buddy having a spare computer on their wrist, a spare tank of deco gas, and a spare couple of lights on their harness, they also have another brain from you and can look at things from another perspective You get plenty of chances...

Good points if that’s your risk appetite I’ve heard it called “the handshake,” but an s drill/valve drill in the shallows with someone you don’t know will tell you a decent amount about how they’re gonna be in the cave If they get offended and refuse when it’s suggested, you can bet they...

What situation do you feel it’s safer to dive solo? And when/where would you not run a line?
