Looking for a detector for my girls (9 and 12), after reading a lot on the forum, it looks like the Compadre might be the best package for the money...simple but effective. I would like to have it with the 8" coil so it can also be a back-up for me if my F-70 goes down for some reason. The Tesoro website says its available with the 8" coil but I can't find it online. Anyone have any info?
