My friend Sam and I left Mineral Wells kinda early, 4:45 A.M, to meet with Dave to install a Humminbird 1199 on Sam's boat. What a great installation job Dave accomplished. After just a couple of hours installing the unit, we headed to the lake where we spent a couple of hours being instructed on how to use the unit. The lake he took us to, showed tons of fish and structure. Great learning experience. I want to thank Dave again for such a great experience. Hope to meet Dave again sometime in the future. Just wanted to share my thoughts with everyone. Kudos to Dave
