Excalibur threshold question

[greenmeanie]

I was wondering if this is normal. When my detector disrciminates against a target the threshold goes up louder which is anoying. I set it for a certain level but yet when it hits a discriminated target it jumps up the volume of the threshold and stays there giving me a headache LOL. So then I have to take my Scoop and wave it by the coil to reset it to the low tone it was giving. But the bad part about that is sometimes there is a target when I start the next swing.

Yeah, I get that happening to me too. The volume creeps up as the machine keeps rebalancing, then it gives a blip when I reset it against my scoop. Same thing happens when I finish digging a target and have been stationary for a while, it blips when I start to move the coil, tone stays the same but it blips. I usually run the Sensitivity around 10 o'clock to 11 o'clock so it may be just a question of the coil run a little hot.

Anybody else have ideas on this?

I've noticed exactly the same thing....I like to "reset" out of any low iron tones that arise quite regularly.

I reset by waving the coil near my scoop, which then leaves the threshold at the higher tone which I prefer as my background threshold.

As for the overall volume, this sometimes has to be tweaked both up and down as different targets can alter the original setting.

The idea of the different tones is to let you know you have gone over either a non ferrous or ferrous item. A ferrous item will leave the threshold running at a low tone where as a non ferrous will be a higher tone.This works on items which have been discrimiated out, for example if you had the machine set to discriminate out a ring pull. It would not give the signal for the ring pull but the threshold tone would alter to at a slightly higher tone. The threshold tone will also alter if you go over a tiny non ferrous item which is too small to give a solid signal.Its another way the machine is telling you there is something there that you have gone over and possibly missed.
