locator/trolling motor interference

[bkft]

Hi all,
Just a quick question: Does running the trolling motor and locator off the same battery cause "false" readings on the locator? I only have a small 14' aluminum boat and not a lot of room for two batteries. If this does cause interference, are there any solutions other than buying a seperate battery for the locator? Thanks!

Yes... and there are a few things you can do... I know lowrance makes a patch of some sort for thier locators, but I dont think they pull out all the interfirence even.. I would suggest you get a small battery like people use for ice fishing. It wouldnt take up that much room or add the weight....

Good luck!

Yes it can cause false readings. What I would do is use a smaller sealed battery for the depth finder. The kind that we use for the vexlar when ice fishing. I use that on my bow mount locator and find that I have to recharge about every other day when fishing.

Glad we were able to help... please let us know what you did and how it worked... Sometime along the way, someone will have that same exact question...it would be good to know how you fixed it.

I have been using a deep cycle battery with a minkota 65 and fl-8 for the past ten years. The combo works well.
The 65 uses a maximizer and will cause some interference. Grounding the negitive of the battery to the boat will get rid of the interference.
A second backup battery is a option if you heavly discharge the deep cycle.
