I have a Lowrance 334C that came new with the boat in 2006. I’d like to get a chip that would show all the wing dams, contours, etc. for Pools 2, 3, and 4. I don’t care about any other bodies of water. What chip should I get? I’ve never updated the software. Will I need to do that before I install the new chip?
Thank for your help,
Boone
