Pin Pointing Question???

For those who use a Nox, I have a quick question re pin pointing...

When detecting I don't really take much notice of the depth read out, but I was wondering what the number that appears on the screen when you are pin pointing?

I ask because yesterday, I noticed that when detecting if I got a good signal with a reading of say 21, when I switched to pin pointing, it would often change to say 8....I sort of assumed this related to the depth, but sometimes it's a positive number while other times it's negative???

Anybody any ideas?

I believe it's the signal number it's trying to pinpoint. Just tried it in the garden with a signal at 22 close to an iron signal of -4 (all metal). If I hit the pinpoint when it shows 22 it holds that number and I get the target. If I hit the PP when it shows -4 it holds that number and pinpoints several inches to one side.
My guess is that if pinpointing appears to be off it could be you've locked the machine in to a number that is somewhere between the target you want and something you don't. Just my thoughts and happy to be corrected.

If that's the case, that's a very interesting feature I didn't know it had...I think I will pay closer attention next time I am out...

To be honest, I don't have any major issues pin pointing with the Nox except maybe towards the end of a session if I get a bit tired/careless...

I do get the odd find in the side wall, and last Sunday I missed one completely but I think that was because me not paying attention to where I should have been digging.

Like you, I had been wondering about the random numbers but had noticed it would lock on to a single number to pinpoint and the number didn't always make sense. I'm still a newbie to the Nox so assume others have already noticed this.
I'm impressed with the Nox's ability to find a target close to or even on top of some iron. On Saturday I was out for an hour in some trashy woodland and got a 16ish signal but with an iron burp. The 16 wouldn't go away but manual pinpointing was giving a mix of signals. Tried the auto and must have pressed it on 12 as I scanned the area. Dug the target and was a way off. The hole produced a lot or iron staining about 9" deep. Tried to pinpoint again and the 16 was off to the edge of the hole and the iron burp nearer the middle. Anyway, this little lady popped up at the edge and always a welcome sight.

Make sure you knock off the horse-shoe (all metal) if you have that on before you hit the pinpointer. The onboard pinpointer is a good deal more accurate if it is not on. I was wondering why it was so off centre and then I realized whenever I didn't have the all metal on it was much better. (I flit between the two and don't habitually use it so that is why it became clear what was making a difference.) Of course I live in a bubble and you probably all do this already ....
