How do you know your detector is set (tuned) correctly for the soil condition of the day, if you don't tune it every day? Things change constantly with the weather and type of soil, rainfall, magnetic storms, negative ions, etc., etc... Many, many times I've been detecting right behind some well known detectorist and find good stuff, they empty out their pouches and have a lot of pull tabs and junk. My wife did the same type of tuning, once she had several men comment that "there was no way a woman was a better coinshotter than them". After a couple hours hunting in the same area the four men and my wife emptied their pouches and she beat all of them put together... Also remember that in those days we didn't have all the bells and whistles on our detectors and we DIDN'T WANT THEM cause many times I proved that a plain detector reads deeper. Once hunting a historical site right after a heavy rain and with plenty of witnesses, I found a shield nickle almost two feet deep, in fact the group dug it up for me. So many times valuable things are missed by depending on these modern identification machines. My engineer and I built the first identification machine in 1970's AS A JOKE, showing it off at a detector convention. That started a race between detector manufacturers, to build their own models. We found it NOT practical because it took too much away from the depth. Instead we went with multi-frequency option which we integrated in the mid 1980's. I've proved that fact too many times in head to head competition, like at the Freemont Expo where I beat every manufacturer in a private test... That's my opinion and experience, of course I have a few hundred thousand hours on the end of a detector and shovel for almost fifty years. That's not to say that everybody should follow my lead, after all, electronics has come a long way over the years and everyone is entitled to their opinion and preference in detectors. And YES, I've dug a lot of junk, tons of it (there's a huge pile on my office porch right now) but at the same time I've found a mountain of valuable stuff that would have been missed by setting the detector to discriminate too high. The TWO detectorist that I've had to my home place to see PART of my finds, always shake their heads in disbelief of the amount..
Good Luck

No wonder I have never posted any finds
