Thanks bajadog, I suspected THAT indeed (pretty much suspected everything thoug!). Yesterday I went to a lake with a fresh battery and the tranducer worked fine (whew). However, I stayed a bit at night and when I turned the screen light on to see where I was with respect to the structure I was fishing the light flickered very rapidly, I think it was doing it at the same rate of the sounder pings! The intensity of the screen light also varied a bit on 2-5 minutes intervals. At this time I had my LED nav lights on. I will run a test without the LEDs and see if it flickers, if it doesn't, I will run a different battery for lights and presto.
I still would like to know how long this setup is supposed to run on a single charge. Fish on !
