Hello..I have a Catalina 27 and the original big round Signet depth and knot meters have long since died on me. I'd rather not get the same big <ugly!> Signet instruments, but I also don't want to pull the boat out and re-install new transducers for a different brand depth / speed meter.The speed transducer is a plug type that you can take out and throw a blank plug into (see pic below). Does anyone know if Navman, Raymarine, Garmin, Airmar, or any other mainstream instrument manufacturer makes a transducer that I can plug into the existing fixture? Depth is the only really important one, but a depth / speed / temp sensor would be a dream come true.Many thanks,Cris HazzardMorning SkyJersey City, NJ
