I bought a new Delta 4000 couple of months ago. I was never able to find anything with my Bounty Hunters. The Delta 4000 changed everything about detecting for me because it was the first one I owned with a built in pinpointer, made all the difference in the world not to mention way more accurate. Ended up buying an AT Pro because I assumed if the Delta 4000 was that good the AT Pro would help more. I do like the AT Pro, but carrying it around after a while gets heavy where that D 4000 never gets heavy. And at my experience level, the D 4000 works as good, for now, as the AT Pro. I have been looking around for a used 2000 myself. I must have got the 4000 right before the price was coming down, paid close to 300 and now I see them at Academy for $149.
