Hit the lake today, but when I turned my Marcum on, it had no power. I realized when I left home I had not remembered to recharge it after its last use (two weeks ago), but thought it would have at least a little juice left to show something, even if only for a minute. Checked on it this morning, and the indicator light on the small charger box (by the outlet plug-in) is flashing red about once per second. I turned the unit on, while both still on and off the charger, and can hear the unit whirring, but still no lights or flashing. Is it just a case of a battery gone bad, or something more severe? Worked just fine two weeks ago, so don't know what else it could be other than the battery. Anybody else that has had this issue in the past?
