What Do You Hookup To Your Kayak Battery?

Interested to hear what you guys use your batteries for when splitting to power up multiple items. 

Fishfinders are the obvious one (and power poles & motors), but I've also seen lights and dash kits...what other items do you guys rig up to your battery in your kayaks?

I believe the vast majority of kayak fisherman on this site run just a FF on their batteries some a SS and or live bait tank. That's about it.

If fishing salt,
FF/GPS get a dedicated battery.
If you want all that other crap, then add a second battery .
This way, when all that other crap corodes out you will have a back up battery for your FF/GPS.
