I figured it is easier to keep threads clean for others to search and find what the yare looking for, so this is a thread for rants and raves about marine electronics for your boat or yak.
I use the Eagle CUda 250 s/map on my kayak and it is a great economic system for a yak..it really does everything you could want and only lacks a color screen. the monochrome does extend battery life. It does GPS, chart plotting and has a good bottom finder.
i use a 8amh 12volt solid cell battery and it will run the unit w sonar on all day and still have plenty of power.
what are you using?
