A tree is known by it's fruit, and the only way to know how someone dives is to dive with them.Uncle Pug once bubbled...
... and the dispensers thereof. Start with yourself.
I actually dived with Uncle Pug once. You've got to be kidding?? This guy can't even afford to buy a full sized hose for his octopus! Or a holder to keep it in. He has to use a piece of old bungee cord he obviously found on the ground while roaming the beaches of Puget Sound searching for dive buddies. Talk about dangerous, he's got a bunch of hose wrapped around his neck! He doesn't have a dive computer. And his flutter kick is a joke! With his knees all bent, he looks like he's trying to clap with his feet or something. He doesn't descend or ascend vertical like PADI teaches, and he's so slow that it takes him almost a full minutes just to ascend from 10 feet to the surface.
He didn't help me much either. When I silted out the bottom while we all looked over a stumpy squid, he never said a word about it. Never mentioned that I didn't have my backup light on our night dive when my primary light died at 100' and he had to hand me his backup. Never said a word about having half a bottle of air when I was dry. Some helper, huh?
After the first dive, it was obvious that one of us was a much better diver than the other - know what I'm sayin'? And still he had the nerve to treat me as an equal.
I tried as hard as I could not to learn anything from a guy like that. However, I maybe picked up a couple things...
