Let me start by saying I'm a recreation diver with the overpriced "advanced" card and the expensive nitrox card to go with it. I'm not a perfect diver, always working on something. My trim could use some work, still adjusting the final touches on my bp/w, but there are some things that I just DON'T do.
I live in MD so most of my experience is quarry diving. Thank goodness for quarries because there's little life to disturb and while it is REALLY frowned upon to crash into the bottom, it does happen at times, but for the most part I see divers avoiding it at all costs. There's platforms for that I guess.
I'm getting to my point. I'm here in FL and went diving at my FAVORITE place to dive, the Blue Heron Bridge. WTF? There were divers everywhere CRAWLING ON THE BOTTOM (I've never been on a weekend). Classes were being taught on the bottom. I saw one discover scuba (I guess) where her guide was literally trying to pick her crawling ass up of the floor. She was crawling on all fours towards a structure to see the fish. I was appalled. I bet 70% of the divers I saw were on the floor. It's not a quarry (where people get pissed if your on the bottom because you destroy the visibility). It's a habitat.
I dive with my wife for the most part, and while I have a long way to go, she has a longer way to go, but WE DO NOT TOUCH THE BOTTOM. Yesterday I was so proud of her as a diver (and myself I guess). We never touched the bottom. We're not perfect, but destroying the habitat of little creatures is unacceptable. Yo-yo'ing buoyancy is unacceptable.
I know I'm ranting, but is this the norm? I've never dove around numerous divers, but is this how most easily accessible places are? Please enlighten me on a different perspective. If this is how people are taught why would they ever change?
Now wonder people move on to tec. It's to get tf away from the masses?
