The xterra is turning out to be a very good coinshooter ,the last 3 outings have produced some nice silver coins ,I tend to use the ex11 in the first 2 hours detecting ,then change to the xterra ,my what fun it is to use and using it in all metal is producing the coins at a very reasonable depth,the 18khz coil will be with us next week and have ordered mine ,just wondered if minelab in the future could make a bluetooth connection between cordless headphones and the detector .
