So I'm in the shopping process for a boat. The boat's intended purpose is coastal with a trip to the Caribbean. My price range for the boat puts me in typically an 80s boat. Listings that I am seeing sometimes have radar units in varying vintages. Some look like they could have been installed in the 80s and early 90s. Obviously technology improves, but does an old radar that still works provide usefulness? My current valuation of radars is that it would be nice to have even if old, but I won't discount a potential boat if it doesn't have one.
