Does anybody have any experience with using solar powered re-chargeable batteries? Trying to keep the depth finder up and running pretty much all the time (8 double "AA"s) without having to tow a supply boat behind me.

I use eight alkaline AA batteries for my fishfinder. A set lasts 5-6 days. I carry a backup set and simply change batteries for remainder of trip. If you want to use rechargables, just recharge them at home. Don't overthink this.

M  y response was to your original post. Your second post about GPS was unknown to me while I was responding.

Anyway, my experience has been that if you need for the sun to shine, it will rain.

I would just plan on hooking both to a fully charged deep cycle marine battery, that way you only need one.

When I get something stuck in my head sometimes it's hard to let go......

I wonder if this would help power a GPS? Or re-charge an ipod? (of which I currently own neither   )

It would be fun to be able to keep the GPS on as it eats batteries.....2 "AA" every 18 hours (garmin 60csx is what Martin uses and seems to the standard by how others are measured). How far you went, how fast you went and where you are. The other option is just to turn it on when you need it.....that's OK to.

And how 'bout a couple of sets of re-chargable batteries for when the suns down.
