Threshold Setting

[BarberBill]

Made an interesting discovery this weekend. My wife and I attended an annual club sponsored hunt that we attend each year. After the last session, while packing up, I noticed that the settings on her SS

So I wonder if that means the MXT is much deeper than the M6 since there basicly the same machine. To my understanding the M6's threshold is factory set just to the point you don't hear it. I love my M6 and like it's simple use but after hearing of the new MXT with tones I may have to put one one my wish list if it is deeper. I would hate to spend the money if it's not much deeper, I've been sooooo hapy with the M6.

But sure worth trying...some are just in disc, some just in all metal and some are tied into both.....I remember Jimmy Sierra sort of sputtering in an old XLT video when referring to threshold and depth increase...Most like to keep like the buzzing of a bee and I know if too loud you are going to miss signals which will be drowned out by the threshold. All in all experiment and read that manual again as certainly plus and minus opinions on the subject as some of your deepest detectors have no threshold at all..

I will be trying this on the MXT the next time I have it out. It is my understanding that the MXT is supposed to give the best performance with a threshold setting that is just audible, but how much compared to silent, I don't know. I'm also thinking some detectors don't have the same interaction between threshold based all metal and the discrimination mode, either. Anyway, it's another thing worth checking on whatever machine one uses.

Almost all, if not all, detectors that have both an all metal and discrimination mode have a threshold in both modes and almost all of them have the disc and all metal mode threshold connected, I'm sure there are more but the only two motion detectors I can think of offhand that doesn't have the disc and AM mode threshold connected is the Goldtrax Baron and Tejon, but almost all of them have the disc mode threshold set.in the silent range so it's never heard. George Payne designed the first motion detector, and the first that had a silent threshold in disc mode. He said he was opposed to using it because it fooled the person using it, but the pressure to compete in the market place required him to use it. He said rejected targets drove the already silent threshold deeper into null and caused a loss of depth and missed targets, but the person using the detector never knows it because the threshold is already silent. That in bad ground, or if the ground balance was too negative, the threshold was driven deeper into null and some desirable targets wouldn't give a positive signal, and if you swung over a rejected target the threshold was driven deep enough into the null range it often couldn't recover fast enough to get a good target that was nearby.
