Hi everybody,am new to the site.I live near York,UK and currently own a Tesoro Silver Sabre Umax which is a brilliant little detector,and have just bought a 2nd hand Tesoro Wolftrax on Ebay.It should arrive in the next few days and I am wondering if there is anybody out there who owns one and can give me any tips and advice .I have bought it mainly because where I live a lot of the fields are contaminated and I find the Tesoros excel in these conditions.
