I think I've tapped my tank once with my dive knife because I saw a sting ray. It was on my first trip to the ocean, so I was excited. But I try not to bother anyone else usually and just like to sight see.
I tapped my tank once with my dive knife - never again - afterwards I found while doing it I'd practically sliced through the lp hose on my secondary and I had to replace it. :depressed:
