How do you rig a fish finder to a tube?

[Lector]

Hey great information TubeDude. I read one of your earlier posts and thats what made me decide on the eagle fish finder. It sounds like you have had lots of experience!. One question, when you say lead acid battery were do you get them and what are they? I would also love to have you send your diagrams to me from you book. Oh, almost forgot....I have a U-boat.

Thanks, Lector
