Not so sure I'd agree with that one.
I took my rig up to Cooperstown NY, since I was staying at Jellystone Campground, and there's a central lake at the site. I figured, "heck, it's water, why not dive it?".
So after setting up camp, I gear up and hop in. The visibility was about 6 inches, and the lake was apparently man made, with a flat depth of about 6 feet all the way across. I couldn't even see my gauges when they were right up in front of my face unless I got a brief opening in the muck swirling in front of my face. So I finally make it across the lake and come out on the other side, right next to a father and son fishing. They say "wow a scuba diver! You see anything down there?". I was like "nah, it's not very clear down there".
I am thinking, well at least I got a chance to impress a couple of folks, if nothing else. So I hop back in the water, and start swimming back, but again I cant see my compass. I swim a few minutes and figure I better stick my head up and see where I am. So I do...and guess what I see? Yeah, the father and son...I swam in a complete circle...lol.
I mumbled "I meant to do that!" and quickly turned and jumped back in again.
