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

I don't think you will find many people that use a GPX to hunt coins. I will use my GPX in a trashy site only if there is no aluminum, because in that case all non-ferous items are usually good targets. But if you are going to a site with a lot of can slaw or modern trash, your Etrac is the best tool you have. The GPX simply only tells you if it is iron or non-iron, nothing more. A Large cent will sound like a nickle, gold, lead, brass... you name it.
If you are going to hunt a site loaded with iron, I've found that you will have to go super slow... after it blanks stop moving and wait for the threshold to return.... then move slow again.... I have hunted a few sites loaded with nails and such.... what I have noticed is that it is hard to hear the deep faint sounds because of the blast from surface targets. It can be done, but requires a LOT of paitence.
Jut my 2.5 cents.

Thanks for the response Mach1 Pilot. I have hunted this place for the last 15 years with four different Minelab machines and done well taking over 100 silvers. The E trac has done an excellent job of finding masked targets down to about 8" due to slight mineralization. Over the years I have removed most of the shallow non ferrous trash in about 75% of the area. Do you recommend any settings for the slower sweep speed? Thanks Rick
