Ok, sent in X-Cal on Aug. 27th and was suprised to find it today back at my door via the brown truck. I sent it in for erratic signals all the time and they ended up replacing the coil at no charge. I dont know about some of the problems I have seen other people having on here but Minelab has been great to me and the service turnaround seems as quick as any other repair place you have to send a product away. Now I have three days to go check it out and see if all is well as I go in for shoulder surgery Friday and I think my detecting days may be over for awhile.....Max the lane is yours for awhile while im on the mend
