I'm flirting with the idea of purchasing the X-70. The only VLF detectors I have right now are two Tesoro Units, which are great detectors, but do not get the depth I would like to see. I noticed Detector Depot offers a package with the 10x5 elliptical, and I was wondering whether the 6" coil might be the better pick. What kind of depth does it get? I have a SOV with the 8" stock, 12" stock, and 15" WOT, and have had nothing but good experiences. I hunt a lot of parks and ghost towns, so I need a coil that gets between junk, and still gets at least 6" of depth. I have estimated that, in ideal soil conditions, I "generally" get about one inch of depth for each inch of coil diameter. Perhaps I'm just missing the deeper targets?
