Through a bunch of "horse trading" I ended up with a flock of VLF gold detectors and have played with them extensively on my property here. The soil is moderately mineralized and well supplied with hot rocks, cold rocks, nails, bottle caps, cartridge cases, shotgun shell bases, air rifle pellets, lead and jacketed bullets and countless fragments of both. I claim no objective truths arrived at, just relating what I liked and had confidence in and what I didn't. An original Lobo went early, the audio was just too week and the depth in discriminate was pretty poor, spoiling it as a dual purpose detector. A GMT was the next victim, it wasn't as sensitive as my Goldmaster 4b and I just couldn't warm up to it. A Lobo Super Trac was tempting but the auto only GB and weak discriminate function made it a gold only machine. A friend admired it and it has a new home. I'm now down to four finalists. The GM 4b is a chest mount and I like its sensitivity to both 1 grain and below fragments and it's depth on larger stuff. I have the regular 6x10 and the large GoldMax coils (both concentric). I will probably hang on to it for meteorites at least because it is easy to swing. My Gold Bug 2 has amazing sensitivity and I am convinced that it will find crumbs better than anything else - besides, I got a smoking deal on it from a Pawn Shop and think I'd better keep it. My MXT is a great machine and I am impressed with it's depth with the 6x10 DD coil. It seems to be smoother and just as deep in discriminate as in All Metal (although it doesn't ID to anywhere near that depth). It is much heavier than the next detector however and I probably will sell it on soon. Last of all, I got a GB Pro, mainly after reading TrinityAU's posts about it. I think if I had to keep only one VLF for gold, it would be this one. I was confused at first why the main display in all metal was the continuous GB reading, but I am now understanding how that helps me know when to grab a GB fix and also how hot and cold rocks affect the GB reading vs how metallic targets like gold, lead, etc do so. The next phase of detector wars - Pulse Induction - starts next week when the ML SD2100 I just bought shows up. I was looking for a GP 3000 when a deal too good to pass up on a hardly used SD2100 with 3 coils popped up. It will face off with my Whites TDI which I have had for a while. That part of the program will have to be done somewhere else since the EMI here is really bad and the TDI hates it here - the Sd2100 no doubt will as well. Of course any sensible person would ask why I'm not out looking for gold instead of digging up my 3 acres here in Gold Canyon (where there is no gold). Good question. I hope to remedy that deficiency in a week or so since I just joined a local club with many claims here in AZ.
