Steelshooter, what sort of run time do you get with those batteries?
My fish camera uses a 4 a/h battery and I have a 7 a/h battery and a 12 a/h battery. I was using the 7 a/h battery running just one sonar unit but when I added the second unit I added the 12 a/h battery. Did want to go dead out on the water.
Don't want to run out of battery at the range either.
