Thank you again to Strollmasta, pasttom, tvr and Tony for your suggestions.
I tried the settings that you recommended, and still no threshold hum, dead silent. On the plus side, I tried (again) to balance in pinpoint mode, and in the soil here i was able to actually ground balance the machine, so that is good news for me. Maybe the sand at the beaches I went to didn't have enough mineralisation to make much of a difference to the CZ at the spots I tried to ground balance...I know there are spots of mineralised black sand (and my PI machines confirm this).
I guess the decision I have to make is to use it without having a threshold hum available, but knowing that I can GB in Pinpoint mode. The reason that I have a dilemma is that it took just over 5 months for me to receive my machine after I ordered and paid for it, which means (to me) that it could possibly be 10-12 months before I got it back if I send it in for adjustment/repair. Tony knows what I am talking about.
Thanks again all, for your assistance, it helped me achieve something.
