Hello, When I hunt in the woods my Fe3O4 meter hardly shows one bar and things sound great and the VDI works fine down to 5-6in...but when I hit corn fields the Fe3O4 meter will jump around. The machine doesn't VDI correctly in these fields either. I assume the fields have lots of fertilizer on them which causes this. My question is- what can be done about it? I turn the sens down and go super slow...is there anything else? Why does the T2 have the Fe3O4 meter anyway? I can already hear when the machine is having problems in tough soil. Thanks!
