I recently purchased a good used X-1 Probe. Worked well the first few times out, now my detector falses low tones when jiggled or swung. I suspect a worn wire somewhere within in the X-1 unit. It doesn't appear to be the probe itself. That works fine when activated. I've tried different coils and detecting with and without the unit installed. The falsing only occurs when the probe is installed. Another weird thing is that my pinpointing with the big coil is way off-center when the probe is installed. I know that these aren't made anymore, which is why I had to buy a used one. Are they still serviced? Also, any ideas on what to look for? The wiring inside the box is fine, so I think its something inside one of the cables. I'm going to miss this thing until I can get it fixed! Time to go back to the Garrett Pro-Pointer until all is sorted out.
