FWIW: The word F#CK comes out clearly through a regulator.
Went looking for a lost prop about 2 weeks ago. Water is only 12 to 15 feet deep but muddy. Bottom is a nightmare - 6 inches of fine silt , then 6 inches of regular silt - then about a foot of muck. Had to use a stake and wreck reel to conduct a circle search. Used a borrowed underwater metal detector - hoping it could find the prop under the 2 feet of muck.
Searched for about an hour - found beer cans , old boat ladder , half a pair of sun glasses.
Viz. is zero and had to crawl along bottom and hold wreck reel line taut to keep my bearing.
Line got snagged on a log and I had to tug to get it free. Line went slack so I crawled opposite direction to tighten it. Still slack ?????? Crawled 90* off that and still slack. Tried to reel in slack and had trouble finding the handle.
Ah , the joys of muck diving. Looped the detector under my arm and used both hands freely to reel in line. Only trouble - no handle on the reel. F#CK.
Turns out - no side plate either - double F#CK.
What a mess - about 100 feet of line wrapped around me , tank and metal detector. Had to surface to get out of this mess. Started to swim to the boat but then the line came tight . Luckily , long stake pulled from mud after a few hard tugs / twists with my body. Had that plus the marker jug and line wrapped up.
Got to the boat and my son had to cut some line to free me up.
