I thought I would pass along that SR Mariner instruments is discontinuing their marine instrument product line. I believe they will still provide parts and service. They have what I think is a great deal going, If you have SR Mariner instruments you can trade them in for new stuff and get a 50% discount. In other words, give them the old broken stuff and save 50% on new equipment. I had my depth and knot log refurbish for cheap money and they both work and look new. You can find them by goggling "SR Mariner" good luck, Jack
