and that is one of the gripes i have with the gmt ,i don't think they make bigger coils for it , all though i'm not sure if that would give me much more depth or not. it does find small gold on the surface , but i think the really good stuff is down deep. i do like the follow the black sand mode on it though,i would just like find some nice nuggets, if i had a camera that would let me post a pic. ihave found enough flour gold to cover the bottom of my 14" gold pan one &half inches. the small stuff is ok but it takes alot more work to get. and now that i'm hooked on metal detecting, i dont want to think i'm passing up alot of gold for lack of detector,prospecting has been in my blood for many yrs now .every one says it's gold fever, but what can i say, theres alot worse things out there. thanks for your comments, i'll read them with great interst , thanks Ron
