Since I refuse to accept the fact that my season is over I went out diggin today for about 4hrs! When I got there my T2 was working great! Found 3 wheat pennies and a little apple charm! After about an hour of hunting I went to change the sense and when I turned the knob the numbers didnt move! I was trying to turn it down but the numbers started going up and then down and back up again! I was about to cry because I just bought this machine about a month ago! I finished up with the setting where they where and then came home to call first texas! After I got home I thought about it and turned the machine back on. Wouldnt you know good as new! In the manual it says you can operate down to -4 degrees. Thats def not the case! It was about 15 degrees here in PA today and my T2 didnt like it one bit! I guess its time to accept the fact my season is over! Has anyone ever heard of this type of thing happening before? I figured its normal because my touchscreen phone wasnt working either! I guess metal detecting isnt meant to be done in these conditions!
