[QUOTE="oldtimerROB, post: 332910, member: 8947"] Hi,the xterra was my first choice but I settled on the Nokta Gold+.Then the Impact was announced and I decided to wait for that.Have had 8 hours usage of it and after 8 hours quickly came to a conclusion to mainly use the GEN mode or all metal mode and not the 8 discrimination modes. I was digging up too many targets and not finding anything.I think the discrimination modes take a hotspot and convert it into a signal.With GEN,the hot spots sound like a larger signal and real objects give a spike signal,so there is less chance of getting a false signal. Blanking out may mean overloading which happens with VLF machines when you encounter a particularly mineralised piece of ground.Threshold is just the background hum which you need when using the all metal mode.The level is adjustable in all machines and you have to turn it down when using earphones.Hope this helps and happy hunting.
