Look at the 2nd photo above ...
The left hand column now shows that we are consuming 0.4 amps, and that is 7 watts of power drain.
But wait .. does the sonar always use this power - or does it vary in its power requirement? The gain is set where I left it on my last trip, set for 15 feet deep.
So what if I turn up the gain to maximum, for 600 feet. Will that increase the power needs of my sonar unit?
