Power supply

[Snowshoe]

What do you use for a power source for your fish finder?

The starter battery that I use for my engine and bilge pump.

 

[Wallijig]

I have my electronics on one battery, starter battery just on motor, and two batteries for my 24v trolling motor hooked only to trolling motor.

I have everything but the TM on my starting battery. The TM is alone on a deep cycle battery.

 

[TNtroller]

TM on its own battery, 2 FF's on cranking battery.

I use a lawn mower battery for the fish finder and have the trolling motor and starting motor on the big battery.
