In my dusty closet I have an old Radio Shack Discovery 1000 with the standard coil. I got it as a gift several years ago. I didn't think much of this detector and rarely used it before...I just assumed it was a toy....until that is, I found that all of the Bounty Hunter coils will work with this model. Does anybody know how to get a copy of the user manual? Would the 10 inch magnum coil make this a good relic hunter?
