Had my sounder set up by Rik last weekend down in Port A. As advertised, the guy is a walking user's manual. Did not get out fishing due to weather and other obligations but learned more than I could ever remember just puttering around the shrimp channels with Rik punching buttons and offering instruction. Rumor has it that Rik is working his way south along the coast gathering new readings for his book. I only wish I hadn't waited as long as I did to get him on my boat. I'd highly recommend Rik to any of our "southern fleet" . Thanks again, Rik.
