I bought my first boat, a 1986 Catalina 27 last Sept. and love the boat. The knot meeter works ok but the depth meter does not work and this is the 2nd transducer. I would like to updgrade the entire system to include wind, speed and depth. They don't necessarily need to be on the same display. I am looking for recommendations on systems that are out there (Raymarine, etc.) both good and bad experiences. Thanks in advance.
