I took out my brand new MMK (finally) into the yard to try it out and learn the basics. I have a White's MXT and so I know what to expect however, leaving the MMK in all default settings except changing it to Mode 3 and adjusting the Gain to 89 (for iron infested land where I'm going Sunday), I get nothing. I turn it on, push the GB to ground balance but it does nothing but hum while the GB button is pushed or when I release the button, it hums for about 5 seconds and then the hum stops. The screen shows 2 horizontal bars but passing the coil over a gold ring or a Canadian quarter produces no sounds. What setting am I missing? I feel so stupid.
