Hey! Dc426. Time Traveler here. I know how u felt.. A couple years back I too found a hand grenade on ft myers beach at he pier. I got signal I dug down about 6 in. Listen for sound again. Still had strong signal. I ended up right at foot a half , there it was. I recognized it right away, but my scoop had torn the lever off w the pin. I thought well it didn't explosed!! I saw the hole in the bottom of grenade, an knew it was a decomissioned. I still have it, I often wish I had some fun with it, back off an call 911. The cops would shut the whole beach down for two blocks, with bomb squad, and probely news helicopters. Ha
