Hello. Trying to figure out this forum so please be easy on me. I'm looking for some advice on the capabilities of the GPX 4800. My situation is that an area that I hunt with my e-trac has stopped producing. The coins are still there at 10-12 inches (maybe deeper) mixed with nails. Is the 4800 a good choice for this application? My biggest concern is how will the discrimination work with coins and can I tell a nickel from a penny from silver? Also looking for a new challenge. Thanks for any input. Rick
