v3 going crazy

[pointer80]

went out saturday between rains with the v3 and it ran great. I had it cranked up quite a bit and i found some clad and three indian head pennies and a toasted v nickel(I am new and just learning the v3. this is my best day so far) I went out sunday and tried a old school yard and the machine overloaded. Went to the old camp after that and the thing was acting crazy. It would not run stable at all . I even had trouble ground balancing because I could not get it to smooth out long enough. Even after I turned it down it still was having trouble running smooth. Any ideas on what caused this? Thanks all.

Did you get to try your other coil?

First test the coil.
Bad Coil Test The best way to check your coil is to set your gain to 15, turn TX Boost on with the coil in the air (not on the ground or around other metal). If you don't get an overload, your coil is good. That is what the detector is designed for - not overloading at the extremes. The probe (zoom on the sensitivity live control) that suggests a recommended gain is not a good coil test.

Then try another coil

If they are not the problem.

EMI
1) Switch to a band pass filter as the band pass filters will filter out more noise than the high pass filters
2) Try different frequency offsets
3) Try the various single frequencies
4) Lower disc sensitivity
5) Try correlate mode rather than best data (if in 3 frequency mode).

Go back to where you had your good day.

If all fails send it in. Rob
