When faced with this decision for our GB49 we elected to go with Furuno because of their well deserved reputation for reliability and daytime screen brightness. If you take a look at commercial boats of various types, the vast majority are using Furuno. They have an optional feature called ARPA which we find invaluable. It allows you to track up to 10 targets and display their speed, course, closest point of approach (CPA), and time to CPA. This is especially useful at night or in poor visibility. ARPA also creates vector lines on the screen showing course and relative speed for each target being tracked. This is good for quickly creating situational awareness. The other feature which can be useful is chart overlay which superimposes the radar display onto your navigation chart. This is particularly helpful for quickly determining if a radar blip is an aid to navigation or a boat. There are other manufacturers which claim to offer ARPA capability but there have been many complaints about accuracy. Both ARPA and chart overlay require installation of a compass sensor unit. I would be leery of any radar that used a tablet as a display device. Furuno displays are rugged, weather proof and high screen brightness. Some people claim that Garmin and Raymarine are easier to use but I've had no issues with learning how to use our system. If cost is an issue, there are many good, previously owned units available on EBAY. I've had excellent service from Max Marine Electronics in Ft Lauderdale.

Can list members suggest what new radars and features they would recommend? I have only used plain vanilla radars that are at least 25 years old. I know there are new features such as a way to predict collision paths
