I had been hunting a site that was near an old settlement in Rockland Cnty NY. I had my detector ( expl 1) die on me. Batteries seem ok, i reset it back to factory specs, i get a tone with heavy background noise. I put a quarter on the ground, sweep over it and get nothing but bad background noise. You know the kind, if you use sensitivity 32, iron -16, ferrous, and gain at 8 running over a heavy iron area. I flipped the detector over so that the loop is up in the air ( no iron/ground up there) and when i pass the quarter over the loop, i get the same mixed tone as in high iron. Not even a steady beep indicating a coin.
Well, i lowered the sensitivity to 18 and turned the iron mask off, left it on ferrous, set the gain at 6 and tried again, still nothing. I thought that if i brought it back to factory specs, i'd at least get a steady tone, and id on the quarter going back forth, but nothing but random like tone id's everywhere.
I pulled off the loop, found allot of dirt underneath the loop cover, removed it, restarted the machine and still complete randomness without a quarter sounding off when it goes accross the loop. I disconnected the loop from the machine to check to see if there were any knick or cutts in the coil wire, still nothing.
So, while the loop was still disconnected, i turned on the machine, tone was produced like its supposed to without the seaminly random tone, so i increased the sensitivity and it became unstable again (without the loop). Am i missing something (other than the loop) but isn't the machine only supposed to react to the coil and when its disconnected from the coil it shouldn't react like that?
After putting it all back together, it still handles badly, does not pick up signals in any coherent manner. Anybody have a clue what might be wrong?
It was working fine on friday morning, put it in the back of the truck (didn't bang it) when to a new sight, fired it up, and hasn't worked properly since. I used the factory nicad's and fresh double A's.
Lookin for advice.......
