Hey Aian, you can pick up a bounty hunter at Radio Shack or somewhere. Harbor freight has a detector for about $50, and I know I now see them for sale ar walmart. The only one mentioned I have experiance with is the bounty hunter, nothing fancy but just right for beginners like i was 5 months ago. sure it does not have all the bells and whistles like the ace 350 I have now but also the BH is easier to operate(it beeps you dig) and if it beeps there is something there, might be trash,jewelry,coins,junk metal, if its making a noise there is something below the ground. Being that its freezing out you may want to wait until spring, iwas just out today and wished I had a hatchet to cut open the ground and that was in a tot lot with wood chips to dig in,so I may be hanging it up for the year till thaw myself. Hope this helped, happy hunting,HH. Check out coin roll hunting on this web site, I believe that is my next hobby till the weather improves.
