 ? About Portable Fish Finder
I've been doing a good bit of research on the Eagle FishMark 320 and similar units. I know it runs on 8 D batteries but I can't find anything that states how long the unit will run on a set of batteries. Anyone who has used one have any ideas? Also, as an alternative to the D batteries, can you hook the unit to a 12V trolling motor battery in a jon boat? |
