I took my Nox for a spin the other day after performing the update (super simple to do BTW). What I noticed, post update, is that the machine is more stable (less chatter) to EMI. VDI #s are more stable. The place I hunted is right across the street from a large cell tower. The first time Chris and I hunted there I had to turn the sensitivity down to 15 to keep the machine stable enough to hunt with. Interestingly, Chris' CTX was unaffected by the cell tower. Post update, I was able to hunt with the sensitivity at 19 and probably could have gone higher but I prefer a very stable machine. I got in to my first ever jewelry spill and a Wheatie/Indian Head pocket spill as well.
I recovered three matching sets of ear rings, two singles, and a copper finger ring. The ear rings have the old screw clamp-on style backs. I'm sure the mates to the singles are there and I will have to go back and locate them. The IHP is a 1906 and two of the Wheaties are 1909-S. Unfortunately, neither of the early Wheaties is the desired "VDB" series. Nothing of real value but a good test of the Nox with the update. IMO, the update is for the better and, if one chooses, the machine can be restored back to it's original version. HH.
