I recently posted about what I thought was a good deal for a Raymarine tridata. Turns out what the fella had is a brand new (unused) Raytheon Raydata. He is offering it to me with new depth transducer, speed and temp transducer and a garmin 16 hvs GPS receiver installed for $475. I know the Raydata is an older retired unit but it does have some nice useful features. I guess my question is : is it worth that kind of money being older and does anyone have any experience with these units and can give me some pros and cons?
