this is my first real metal detector so i can't compare it to any other machine but it finds stuff. its very fast and picks up the smallest signal, i dug a target 4 inches deep that turned up being a single bird shot from a shotgun shell. this hard mississippi dry red clay makes it hard to find stuff but a little rain helps a lot. i still got a long way to go trying to learn it, i'm getting better picking the trash before i dig but the copper wire and brass targets show up as coins but i reckon thats with most metal detectors. a lot of cans show up as something good also. the little town i live in has a long history that dates way back and a lot of the people that lived here were wealthy but i am learning fast that don't mean they lost much money. i think that money was convened a lot better then as it is now. i think this mx sport is going to find anything under ground if i go over it so all i got to do is hunt. with all the trash its going to be a real challenge to find gold, because all the different grades of rings and bling shows up in so many combinations. so far all my gold targets have been foil candy wrappers or pull tabs.
