I have been noticing while hunting that my screen takes a long time to change while hunting in trash. For example, I can go over a 31-31 on the cond. screen and while I can hear high tones during the sweep, it seems to stay on the 31-31 until I stop the swing and find the threshold. It does the same thing in Smart find, the cursor will not move with the tones. It seems to just freeze up, is this normal or am I doing something wrong?? Your help will be appreciated. Thanks
