I sent Tesoro a machine I considered a candidate for the scrap heap and not only did they fix it, they did it fast and efficiently. They have the best customer service of any of the MD companies I've dealth with. If you're a newbie you'd be doing yourself a great disservice if you don't consider buying a Tesoro. I'm not financially connected with Tesoro in any way (wish I was though, with customer service this good they must be doing ok). I started with a Cibola and I still haven't found a machine (other than another Tesoro) that pinpointed as tight or made it as easy to tell the difference between an iron target and a non-ferrous target. I'm really considering ditching my Whites machine because its not going to get a lot of use when I get out with this Tesoro Tejon.
