Troubleshoot Discovery 1000

[farmer1]

I recently acquired a Radio Shack Discovery 1000 (identical with a Bounty Hunter IV) with the intention of locating some metal farm machinery parts I lost in a hay field. It appears to be in OK condition, that is no obvious corrosion or broken parts etc. but when I replaced the batteries and tested it it doesn't work very well at all. With it in all metal mode, sensitivity at 3 O'clock and discrimination at zero it will barely respond to a pair of stainless steel kitchen scissors and a 6 in cold chisel but not to a woodstove poker etc. nor to pocket change, platinum, gold or silver braclets., It will respond to the scissors & chisel if it is swept along the length but not so much when swept across. It doesn't respond at all to the machinery parts I'm trying to locate. That is when samples of the items I'm looking for are swept, nothing. The response is a chirping sound doesn't matter which mode. ( I expected to hear a tone in tone mode but no)

Any idea what is wrong with this unit? Anyone know of a fix?
