It's my streamlight stinger DS led. I know it's was only a $150 flashlight new 5 yrs. ago I have had this light forever and it just came back from Baja Mexico when I was in the race 2400mi. away from home. To lose it at work seams kinda just bad and a metal detector could be useful for all sorts of odd things.
At the time of typing this I had purchased a used Bounty Hunter metal detector off CL and found my light within minutes of searching the area where I lost it. I forgot to add it's 10degrees out and I'm not spending anymore time outside than absolutely necessary.
