I was reading a Western and Eastern Treasure back issue that I bought from George Streeter’s shop and saw an interesting blurb about discrimination. When people start in the hobby I think they assume (as I did) that more discrimination is good. Iron? Yuck mask that out. Mid tones? Most nickles aren’t silver. And worse: Pull tabs? I don’t want those! Crank that disc up!
The article stressed that zero discrimination is best. Here’s why…
First off the higher you crank discrimination the more you kill your detector’s depth. And the good stuff is deep. Second, targets lie. I’m starting to dig more questionable targets that may fool any level detector because they are lying (pun!) on their side or next to a bad target. My first mercury dime bounced all over my AT Pro’s display. I almost didn’t dig it. In my back yard by the barn where previous owners dumped their trash, it had company down there.
Third, and what the W&ET article’s point, how will you know when you are near human activity if you don’t hear the iron? The iron speaks to you, “Slow down you’re getting warmer!” This is especially true if you are hunting fields. George told me, “If you want 1800’s silver do a house with slate roof and stone foundation. If you want 1700’s colonial silver, just hit any big field and look for pottery.” Or do even better, listen for the iron!
Having moved up from the AT Pro to the Deus I admit I miss the Iron Audio button and it’s grizzly grunt song of iron. Yet my Deus does have a cool feature… I can turn off discrimination and notch (or silence a range of sounds), so my detector isn’t losing depth I’m just not hearing the iron. But you know, I think I’ll be turning the notch down too.
Spend a hunt with your largest coil digging absolutely everything, zero discrimination. You’ll come home with plenty of junk, but hopefully that much more silver and relics. Good luck and happy hunting!
