I did that 2 weeks ago at Clearwater beach and found an aluminum can also but after I reached in to try to locate the offending target it and almost cut the tip of my finger off!!!!

I know I know be careful when going that deep and knowing it probably was a Can

. Anyway there was blood everywhere and as I walked back to the truck, after pulling out the can, putting it in my trash pouch and filling in the hole it looked like a CSI crime scene, with a blood trail to the getaway vehicle!!!! Headed off to the bathroom to treat myself as people stared at my blood covered hand, no one ask if i needed help, go figure, cleaned up the wound and bandaged it up. Luckily no stitches required, but my detecting day was done
