As I posted yesterday, . I went to a local park, had good results and everything it worked as it should. I took the Multi Kruzer to the same park, today, and had a problem. The threshold will not hold. After ground balance, the GB value will stay on the screen and I can hear a threshold. After about 5 seconds, the GB value disappears and so does the threshold. When I try to access the threshold setting under "settings," the cursor skips over "Settings" and goes directly to "iSat." I am searching in 3-tone, 14 kHz. I don't remember this occurring yesterday. In reviewing the users manual, it seems to say that the threshold audio is only available in the GEN search mode. Is that correct? I swear that was not the case, yesterday. Today, I was still able to detect targets, but they were fairly shallow. HELP, ANYBODY!
