Fascinating!
I can relate!
Because sometimes I'll go on a fishing trip with my non diving buds, and we'll stay at some lake resort. I always take my snorkeling gear to scavenge the boat docks.
Well I was cruising the bottom of the marina with my hands out in front (dark water), and I felt a tingle first, then it grabbed me by the booboo and scared the &%$@ outta me. My mind said "ELECTRIC EEL!?!". I'd heard of people turning South American critters loose in the lakes around here, and at first that's what I was thinking. But at the surface I saw electrical lines everywhere and figured that's what it was.
I heard of a guy down at Lake of the Ozarks that dons his scuba stuff, hops on his jetski and scavenges "Party Cove". Heard he finds a lot of expensive sunglasses and resells them.
And last summer, a neighbor bought an afternoons worth of beer at the tavern, just for jumping off the end of his boat dock to retrieve his prescription glasses. 6ft deep, about thirty seconds. My first and only pro dive job.:crossbone
