On the old KODAN and Furuno
sets I've played with, considerable fiddling with gain settings was required to "see" thunderheads and squall fronts, but once you've figured it out, you can get a great deal of information from radar "avoidance bearings". There have been occasions when the boat's been bracketed by lightning
strikes and downpours on either side while motoring in a dry corridor, thanks to "radar weather
I have never managed to see weather with radar. I think there was something wrong with my old radar set, which was somehow limited in range despite my having replaced the magnetron.
It sounds very useful, so I'll try to figure it out with the new radar.
I generally leave my radar running all the time. The 4G radar is more free from clutter than pulse radars I've seen -- I guess better signal processing. This greatly improves the practical effectiveness of guard zones since there are many fewer false alarms, and so I've starting using guard zones quite actively. It really helps backup the watch, I think, by sounding off in case some object appears. For example, I almost smashed into a big channel marker buoy in Brittany a couple of years ago -- just didn't see it for some reason -- would have been an utter disaster -- the radar guard zone really gives you some backup against such cases.
I have even used the guard zone at anchor
-- I spent five days at anchor
in Ushant last year in a howling gale, anchored out with the big ships in deep water
, and I was concerned about the Douane cutter
swinging into me in the night, so I just left the radar running and set a guard zone.
So I don't really use the instant-on capabilities of this radar, myself.
