I can write only about coin detecting in parks as I have yet to understand the practical aspects of gold detecting. The GR indicates coins with a sharp signal: nickels: 56-62; pennies: 77-84 with copper coins in the upper part of the range; dimes: ~86; and quarters ~88. Aluminum and jewelry tend to be erratic in the 55 - 77 range with lots of different values shown for a given target. The 90s can be difficult with lots of iron and hot rocks alternating between the very low IDs and >95. I have not yet hit a valuable target in the 90s, but I'm sure they are there.
I can't say anything about gold. I am having trouble developing a protocol for prospecting amid the hot rocks and deep forest duff of the Klamath Mountains. I am reasonably sure my problems there are "operator error" not problems with the GR. I'm eager to learn more this coming Summer.
My experience with Nokia has been excellent. I fried the power unit when I carelessly dipped the back of the unit while fording a river. Nokia replaced it even though it was clearly my fault.
