T2 upgrade ground balance issues

[barrywk]

I got my t2 back from upgrading and have been out with it three times,in three different places and used three different coils. In discrim it seems to be doing fine and most to all the chattiness is gone.The issue is in all metal,and after i ground balance (Auto and Manual) i am getting ground noise on every sweep back and forth which makes it very noisy.Its like its not been ground balance and its reading ground mineralization.I have tried it at different sense and nothing works.Also it constantly has a read out of 3 or 4 with each sweep unless there is metal under the coil.Its very consistant with every swing and very irritating.Is anyone elses doing this
