Excalibur II discrimination

[Au79finger]

I have a new excalibur II and I'am trying to figure out if it is broke. While in disc mode and disc setting maxed at 17 the unit will respond to copper, lead sinkers, pull tabs and black sand on every swing.I have tried it with sensitivity on auto and down to 1 and nothing changes.The only thing it will null on is iron when disc set at 1. Even then it doesnt recover untill swung 2 ft pass the iron. It seems to be hyper sensitive and won't discriminate anything other than iron. I have also located in pp then switch to disc mode to learn the different tones and it only responds half the time on mid dept targets. Trying to figure out if its a learning curve or a broke unit. Any input from experienced users would be appreciated.

If like the Sovereign which it should be that even at max disc you will still get copper pennies and even the zinc ones, but no nickles or some pull tabs, alum foil and iron.Some of the bigger allum screw tops or can will give a good signal too.
Now when swinging the detector and it sees iron it will null out the threshold and come back with a very low tone almost like a growl sound and when it sees the next target the threshold will change to that target and keep that tone, just lower volume when you go past it until it sees the next one. i If you get a signal in PP and switch to disc and the signal is gone is because you have it disc out or it is iron, so most run with no disc at all so only iron is disc out and you can hear everything else and let you decide with the different tones which to dig and which you don't want to dig.
If you are a beach hunter you want to dig everything other than iron if you want the gold, but if you want to run it a little higher you can turn up the disc, but don't reject the nickle as a lot of gold reads in that range on up though the pull tabs.
If you want to see if the disc is working right use a nickle and swing it across the coil while turning up the disc and you will see the threshold will start breaking up than it will null as you turn it higher, then you know the disc is working right, just make sure you run it lower than when the nickle is breaking up.

Thank you rick for the feedback. The nickle did null at 12. Got it figured out now. Dig everything but iron! LEAD SINKERS FOR SALE

That seems pretty much it. I don't dig iron, but I have pockets full of pull tabs. After a year or so you should be pretty good at guessing what the tones are telling you. It is possible to be 80% correct at guessing your target if you have the experience with the machine. Say 100 hrs or so. I have used mine for approx 30 hrs and am getting comfortable with it and can avoid the large aluminum object fairly consistently. I found two 14k gold rings with tiny diamonds, three silver rings, one with a large diamond, a 14k gold and diamond pendant, silver and diamond earrings and $13.00 in clad this weekend. All of it was in a trough where the waves were breaking on the beach. When I first got this machine I probably would have walked over half of it without realizing it was there.
