Excal Not masking IRON

[Nitemare26]

Hey guys, My detector battery ran out the other week and I ran it for a while before I realized all the noise was because the battery was near dead. I went home and charged it but now my excalibur wont discriminate IRON . It is really weird. The discrimnation knob works I can turn it up and block out iron and coins with it but the weird thing is bobby pins are a high tone than nickels so if I block out bobby pins I have to block knickels, I have checked the coil wire and there is no splits, It is only 2 years old, is there a way to do a factory reset? Should I pull it apart and look for bad parts and connections?

Are you sure your sensetivity isnt set too high? the only reason I ask is I know sometimes I can make bobby pins and iron sound good if I set the sensetivity too high ...

Yea unfortunately that is not it. I had tried many settings and I asked a guy with an excalibur and I threw down some of my finds that were iron and that range and his machine was masking when he went over all of them. My machine no longer knows Iron it treats it like any other coin or jewelry, I tried unplugging the battery and turned on the machine to make sure I used all the juice in the capacitors to maybe try to reset any memory but no luck. I think possibly a software error or however the machine knows to mask the factory chosen metals is not working. I don't know enough to say water in the coil or a bad coil would cause that but I really don't think it would.

Ok I just got it working. I dont know what fixed it, Maybe I didnt have a full charge. I was at 12.4 v yesterday when it was acting up and took it to 14.3v today. I also cleaned the battery connector and pack with deoxit maybe that was the culprit I am not too sure. If it acts up again I will post Thanks for the reply!

NEVER heard of that problem. High sensitivity will cause WRAP AROUND on most detectors causing iron to sound like a high tone. Sounds more like you said it was the battery being under charged. you got a 12.4 v.... but thats not under load. The detector is designed to maintain a certain DCV a weak battery could sure cause it to squirrlie things.

Im pretty sure your right! I took it to full charge and now it is worlking! Low volts will do weird things it seems! Id love to look in to a lipo mod I heard the higher volts gives more depth!

ONLY if the detect would allow it to be used. On the explorers they specifically say do NOT use lipos because they create to much voltage. Joe uses a Lipo, but its a 11.1 dcv and has to remove the pod cap each time. Its better to under charge on the lipos.... they last longer. The thing about lipos is they have additional wires which enables the charger to look at each battery and ensure they all are charged equally. The simple red and black wire will not charge lipos properly. On the ML pods the rechargables may get a charge to 14.2 dcv.... but one battery maybe over charged and another undercharged.... one reason they drop off quicker.
