Please respond to this ONLY if you have experience with BOTH machines. I have used a Vaq since last summer and like it very much, not having a display doesn't bother me, but as I get older I wonder about some hearing loss.. I have used TID machines before, so I'm wondering if I might see an edge to using the Xterra over the Vaq. I'm talking about the accuracy of the disc circuit and the I.D. on the display. I hunt parks, old plantations and homesites, gulf of Mex beaches(not much mineralization), relics coins and jewelry. Thanks Tom
