Randy,Bob,Skip, et al: Thanks so much for your comments; and thanks, Bob, for the photos. I really like your "thinking outside of the box"- a "quick and dirty" method,Skip. It sounds like an ideal way to initially test a fishfinder/depthsounder( or maybe act as a permanent solution?).Also, my gratitude to Keith for maintaining this invaluable site! Best of the season for all, Harry Elmslie, Thunder Bay, L. Superior
