Hi again, still looking at a couple machines like the etrac and V3i but I might buy a good cheaper detector and wait on the big detector purchase later (nothing wrong with 2 machines). The tesoro vaquero really looks good for a number of reasons but now the coil decision is the next issue. I was going to mix it up between the double D coil and Concentric Coils. Should I buy after market or stick with tesoro coils? The new vaquero come with 11x8 or 9x8, coils, which has better depth and which one would you buy? Also, I would like to buy a second smaller coil to go with the machine, which one and what size? Thanks again for your help....much appreciated
