Yeah, I went back and looked when I realized it was gone...the next day. I have only myself to blame cause I put it behind my leg while sitting. It was already dark and I was working off the lights from the pavilion. I even thought to myself "that's not a good spot. I could forget it over retrieving a quarter'.
At least I am glad that I abused it, stuck it in wet saltwater sand with no protective cover, knowing that I'd upgrade within a few months. It was the fisher that came with my machine. I didn't know it would cost $45 to replace. I figured it was a $20 item. Just got a sand scoop and lesche digger, I don't want to upgrade just yet.
I recently upgraded my pack to a really nice deep one that goes over my shoulder and has a large zipper opening. When I got it, I thought...I'll never lose my tools out of this. Now I know to be more aware while using my tools...
At least it wasn't a Garrett and it's a lesson I'll always remember, especially when I'm out with my more expensive tools.
