Lost truck keys found and recovered from Saratoga Lake, NY

Matt called me at 6pm and said he had dropped  his ONLY truck key and faub  into the water which was about 4 feet deep as he was getting out of his boat and onto the dock.  He had searched for a long time but was unable to find it. I rushed down to the lake immediately as it was a race against daylight. The bottom of the lake was all muck and weeds. Not a good situation. I decided to go in without the detector and just use the probe but that only stirred up more cloudy muck which would only bury it deeper. I abandoned the probe and I chose to make a visual search  trying not to touch the bottom.  Because I was moving so slowly and carefully, I could not stay down near the bottom so I asked Matt if he had a weight of some kind to hold me down. He had a small 6lb anchor which did the trick. After 20 minutes I saw what looked like a glint of the key ring sticking out of the mud.  I had found the key.  We were both thrilled and very lucky!  It would have been an expensive nightmare for Matt to have the truck towed and get a new key made from the dealership (without a spare) to make it from. A very happy ending.
