The Mega Imaging looks great and I am considering buying the 9in when they are released. They say it has a 2.5 amp draw. I currently have 3 batteries on my boat (2 for 24v trolling motor, and 1 starting battery), but will this new depth finder drain too much of my starting battery to have it start the motor after a day of fishing? 2.5 amp draw seems like a lot for a depth finder and I have no more room for another battery.
