I just got my Xterra 70 back from Minelab for warranty work and Minelab has one of the best service managers around. Her name is Sandy Burton and she is a true professional. People tend to flip out when their new detector breaks, but she handled the crazy guy(me) with kid gloves. She delivered on every promise she made and she got my detector back to me in record time. Nobody likes to send a detector back to the company, but you can rest easy with Sandy. PS, I got a chance to give the 70 a work out today and it is a real performer. I used the 10.5 7.5 htz coil today and I would swear that I was swinging a lightweight Explorer. Found some silver and a couple of wheats, with some 9 inches deep. Even with the bigger coil, the detector was light and responsive. R.L. Johnson
