I have one!
The JRC 1000 is a basic radar, but with a lot of fairly advanced features; helpful if you use them (most of us don't). I live in the California Delta (where radar is WAY OVERKILL!), but I also sail for 1-2 weeks/year on the NorCal coast (where radar is a BIG HELP!). So I don't use it very frequently, but when I have, I've been both im-pressed and de-pressed. I guess it's best to say that the performance (or maybe my interpretation of it) has been eratic. Don't know whether that's the fault of the unit, the conditions, the target, my interpretation of what I'm seeing, or other factors. The first experience I remember was a delivery to SF Bay from Stockton (80 miles inland), in clear weather, when I turned the unit on and it didn't see a steel/concrete 80ft high bridge 2 miles away, on any range setting! Then a trip In perfect clarity, where it didn't see another sailboat, with it's radar reflector up, 1/4 mile away. Then a trip to Bodega Bay, where we left the harbor at 0500 before dawn, in pea-soup, and every navaid was right there, in line, just like I was looking at it in clear weather! Wouldn't have wanted to make that transit without it!OK, OK, OK. The 1st two experiences were when the unit was brand new (to me). The third was after I had some time to get used to it, feel out it's idiosyncracies, and understand how to interpret what it was telling me, which is a definite learning curve.Oh, and over the winter 2 years ago, my storage unit (where I had the thing stored) was broken into, and the Bas***ds stole the display (I guess it looks like a TV set!), but left the scanner and my radar mast! JRC was very helpful in replacing just a part of the unit, and the price was reasonable (don't recall the exact amount, maybe $500??).And it's very easy to install, setup and practically tunes itself on the initial setup.If I had it to do over again, based on the bargain-basement cost of the 1000, and the help JRC has given with parts, I'd definitely buy it again, based on a need for occasional use, but be prepared for a little learning curve, and some frustration getting on top of the curve.
