get a hold of minelab? my wifes xterra 30 works better than my quattro. i buried a dime n quarter last week and its been raining so the ground is plenty wet n the xterra picked out them both but my quattro didn't see them, occasionally i got a 10, -10 or 12 on the display in all metal. coin n jewelry i got nothing. but i bury a quarter an inch or 2 down and it picked it up (the quattro) but kept giving me 35,37,32. a quarter should read 37 or a definite 38. so it is of my opinion that it is junk and need 2 send it 2 minelab for repair. OHHH YAAAAAAA FOR ME!
