Yes, it can be done. I have one site which has a lot of iron in it. A house stood there a long time ago. Since then not much has happened in the area but goose hunting. I set the Deus at the 74 khz frequency and on Deus fast, with no tweaks and pulled more than one of these itsy bitsy tiny bb sized shot from the site. The shot is sitting on the dime for comparison. It also likes colonial coppers, civil war buttons, etc. Gold rings, cannonballs, all those annoying BIG targets. View attachment IMG_0553.jpg
