Is this something I can just hook to my trolling motor battery or do I need something separate?  Space is limited so if separate is there something small I can use?

 

Thanks,

Yes, you can just use your trolling motor battery, if it is 12V (not a 24V or 36V set up).

I'd be concerned about interference from the trolling motor causing noise on my fish finder.

I'd use a separate one.

I guess that depends on the trolling motor. I have my Elite-4x HDI on my trolling motor battery and haven't noticed any issues at all. I have a Minn Kota Edge.

I have the Endura,  I thought I would be able to mount the transducer to the trolling motor but no such luck, the rudder on the trolling motor takes up too much space 

You may consider a sealed lead acid battery for it. A 7ah 12V SLA and charger should be around $20-30 at a battery store. It will weigh less than 3 pounds and will run that unit all day no problem.

That's what I did. I have a small 12ah 12v sealed battery...lasts me two full days of fishing and charges fairly quickly. I carry the battery and fishfinder (elite-4x) around in a small waterproof lunch box. The battery probably weighs around 5-6lbs and only has a footprint of about 4x6.

To be honest, I never tried hooking it up to my trolling motor to see if there was any interference...I had just read not to do so for that reason.

Who knew,  I had a battery sitting around.  Works perfect, just have to go find a charger for it.
