What Amp fuse to use with the 12V AA power supply?

Hi everyone,

I recently built my 12V AA power supply and have rigged my yak for the FF but the only thing that I can't figure out is what fuse to use? How many Amps?

Any help is greatly appreciated.

It might depend on your fish finder.  Most of the fish finders we have in kayaks draw less than 500 mA  (0.5 A)  A three Amp fuse will be more than enough and I think that's what most fish finders come with these days.

Thanks Brian! Looks like I am good to go.
