[QUOTE="mbasko, post: 318858, member: 4485"] In my experience trying discrimination on various Minelab PI's they don't block out iron entirely as such. They blank out or make the signal choppy, as Condor says, which can take some getting used to. It appeared to me to only work on reasonably sized iron that was also reasonably close to the surface i.e. not reliable on small or deep iron. I've never spent a lot of time using it but my own opinion is that it's not overly reliable & best used in only the most junkiest places until gold is confirmed there then dig everything again. If your blanking out large iron targets close to the surface you're blanking anything underneath them too. Easier said than done I know but digging up the targets is the only 100% reliable method regardless of detector used IMO. [/QUOTE]
