I was out on Monday, I hit a few trash targets, then my threshold disappeared (that's the trouble).  I flipped the toggles, twisted the knobs, nothing would fix it.  I turned it off and back on.  My threshold came back momentarily then disappeared again.  As I switched off, "Low Bat" would show on the display.  I replaced batteries when I went out today and it worked, initially.  I hit some trash targets, then a few minutes into it, my threshold disappeared again.  I tried every adjustment (threshold, sensitivity, bands, disc & notch, tone, on & off) and nothing.  The batteries were brand new out of the box I bought last week.  Anyone know what's happening?  del.
