Hi all, I was running two tone ferrous today and I was using the relic program with the 01 thru 31 conductive line disc'ed out and along with the low tones and occasional high tone I was getting alot of nulling. Cannot remember if this has happened before or not. Is that normal to still get that much nulling with such a open pattern? If so is it being caused by what little disc. I'm using? Thanks all and HH.
