XT70 not working

I've about run out of ideas! If you've tried a Factory Reset, if you've tried a different coil, and if when using Auto GB the numbers still bounce around outside on the ground as well as indoors in an airtest, I'd suggest you call Minelab and visit with one of the techs. It might be a glitch in the software or maybe one of them will come up with something I've overlooked. Sorry I couldn't help. Keep us posted as to what you find out. HH Randy
 
Digger :The detector works ok inside the house, sometimes the numbers jump a couple #s, like you wrote in your article, but it seems to work right in the house.
 
On airtests, the numbers shouldn't jump when you continually sweep a target at the same distance from the coil. If your's are jumping, there may be a problem that is made worse by the effects of the ground. Do you have another coil to try?
 
I have the MF Concentric, and the 6 in, and 10x5 HF coils., , Concentrics don't do well here, heavy mineralization.
 
If you have bad mineralization you may have the sensitivity set too high for the conditions.

1. With the MF Concentric on, go outside.
2. Set the sensitivity to 15.
3. Find a piece of ground free of targets.
4. Auto noise cancel with the coil waste high.
5. Auto GB a couple of times over the exact same spot looking for consistency in the GB number +/-2.
6. Tell us what that GB range is. i.e. 16 to 18.
7. Put detector in All Metal AM.
8. Pump the coil up and down over the ground like you were Ground Balancing it, and tell us if the detector is spitting out random tones & numbers with the sensitivity at 15. If it is, begin decreasing sensitivity till it no longer reacts. If it isn't, increase sensitivity till it begins to react, and then back the sensitivity down one number. Tell us what that number is.
9. The relative mineralization can be measured using the following procedure:

Please take at least three readings in the exact same spot and tell us the range of numbers.
10. If the soil is heavily mineralized then using a DD coil is the best bet, also not having the sensitivity too high is important, I would also use GB Tracking as more than likely the soil is also varying quickly, and I would also turn on Target Stability.

Barnacle Bill: Thanks to you and all the others who tried to help me, I tried to do what you said in your last post, but things changed every time I did it. I just boxed up the detector, and am sending it in to Mine Lab, I';m tired of messing with it. Again, I thank you and the others who tried to help, it was really appreciated.
