A first for my list of many searches started when a kitchen knife was dropped into a lake where children swim. Fearing that one might step on it and cut their foot a hunt was started. It needed to be found. I joined in on the second day of searching. Within a half an hour the owner, who was new to detecting and also metal detecting, found the sharp blade.
We both learned form this experience. Peace of mind is very valuable and that being successful at metal detecting requires persistence and knowing what the detector is relaying to you.
There was no real smile to photograph, just the knife. Yes, the owner was very appreciative and thankful for my help that I gladly gave.
