I have your exact detector and the Iron ID Squeeze feature had me a bit uncertain. Your explanation told me exactly what i needed to know. Been using a Gold Bug 2 and it works great and picked yours up at a good price as i want to follow the black sand for drywashing and find it does so much more.... Can't wait to get out and test it. Thank you from the Sonoran Desert of Arizona..... Home of "Lots of Dust" :)
How has the GMT worked out for you? I have a GMT and am learning how to use it. Any recommendations for prospecting/detecting clubs in Pima County? Cheers!
Dear Kevin.... Here is the most direct answer, gold detectors come in two main categories Very Low Frequency & Pulse Induction. The main important operational features of a VLF Gold Detector is ground balance or " ground neutralizing ability" or the capability to adjust the VLF to operate in highly mineralized soil conditions where gold is typically located, including lots of natural iron content or unique mineral conditions like salt, or alkali or just wildly different rocks in one location. This allows the detector operator to "tune" the detector to mainly "ignore or cancel" out local mineral conditions that can produce false target signals or produce too much back ground "noise" that can overcome or obscure a small gold target from detection. Another VLF Gold Detector feature is automatic ground tracking that adjusts the detector as the operator sweeps the coil over changing mineral conditions. Another challenge with VLF gold detector is the problem of enough signal gain or "application" of the very weak "receive or RX signal" returning or responding to the detector's transmit signal. Too much gain or amplification can overcome a faint gold target response so learning how to adjust these features properly enables the operator to differentiate mineral responses from metal targets. Whites Electronics Gold Master GMT does all these functions extremely effectively as well as a very accurate iron ID system, gold probability digital readout, mineral content indicator and black sand indicator. The Self Adjusting Threshold feature automatically tunes the audible threshold for mineral changes to keep your "electronic ear" or audible threshold tuned very finely so you can hear any target signal nuisances. Gold typically has a very soft, smooth and distinct zip sound unless it is near the surface or very large. Mineral sounds are usually very "different" from gold sounds ranging from a wide "waaah" sound or chattery broken indistinct variable sound or sometimes various minerals sound exactly like gold but will fade when you simply elevate the search coil slightly or re-ground "balance out" the offending mineral sound. Using a gold nugget target and other targets of iron, aluminum, brass, bottom caps and hot rocks for comparison will quickly reveal that learning the unique sound of gold alone is the trick. Proper search coil smooth and low sweep speed, correct ground balance, just enough gain for clarity, fined tune your threshold to just the right amount of hum and listen for a repeatable, distinct and identifiable gold sound. Good gold detectors have these features and functions but your are the most important part. Pulse Induction Detectors use a brief and very powerful transmit signal then "wait" for a short time interval before sampling for a potential metallic target. The "decay rate" of the transmit signal is very fast in minerals typically and the metallic target will transmit a return signal much longer than minerals. So by setting the "timing" of the target sample above the decay rate of the local minerals the pulse detector can effectively "ignore" problematic mineral sounds. Whites Electronics TDI Pulse Scan also ground balances and has a unique high conductor, low conductor or all setting that provides a rudimentary discrimination with a little practice. When soil conditions are beyond the VLF gold detector the Pulse Detector provides opportunity to find gold.
I have the GMT detector have had it for years now, I have had luck, it's extremely sensitive, Great detector, Thanks for video 📹

I dig it ALL, All of it is DUG.Everynow&then I get a NUG.
Would it be worth it to buy the 8x14 max gold coil for gold and meteorites using the GMT? Thanks for the video!
Good Machine ..... Finding any 50 gram nuggets ?
