Discrimination Query… Gents (and ladies), Ive been enjoying this hobby for the last 2 years, however certainly don’t consider myself an expert, I believe there is always new things to learn, I realise different people use different techniques and what works on one detector won’t always work on another, so interested in getting comments and suggestions to my query.
Last weekend I was out hunting a friends paddock with my AT Gold, I found a nice 1933 silver and a few bronze coins along with a old Victorian broach, all was going well until I came across a heavily iron infested area. Signal and iron audio confirmed it was iron, it read around 34 at around 6 inches, I dug it out, got another target, same reading and same depth, dug it out, so I was left with 2 heavily rusted 4 inch nails, I pumped up my discrimination to 40 as the nails were reading between 34 and 36. A while later I hit a good strong signal reading 54, iron audio was on but didn’t alert. It was registering at 8 inches, solid clear signal, dug it up, depth was correct at 8 inches but to my disappointment it was another rust 4" nail, then I hit another 56 reading at 6" with iron audio not registering, but to my frustration it was yet another 4" nail. I had 1 bar battery power left, could it be this that was causing it all?
