I have a Lowrance LCX 113C HD and a Lowrance LR 1500 radar unit. Supposedly you can now overlay the radar image over the map if you upgrade the software (released 9/20/07) but you need to have a NEMA compatible heading sensor to make this happen. The KVH AutoComp 1000 supposedly works. Anyone already do this? Any comments on the KVH sensor or any other brands?
Thanks
 
I have not done this, but friends who have, have found that gyro rated compasses do better, especially at high speeds. Some of the auto pilot, like RayMarine Compassas are gyro. You might also ask Ben Elison (Panbo)--or "The Hull Truth" electronics forum--these are the places you are most likely to get folks with experience with this instruement. I choose to go with a separate Furuno Radar--but personal perference of two screens, rather than overlay.

I have a RayMarine C80 system that already has overlay capability and it too requires a NEMA/Seatalk heading sensor according to RayMarine. Before you go out and buy one, try it at normal cruising speed and you might be just as surprised as I was when I found it resolved heading pretty well by using the GPS input and gave darn accurate results. Of course at slow speed or stopped, you're SOL but I suspect the Lowrance would do the same thing.

At least you can try it but just don't count on it....

When I worked for Sperry Marine, we developed something called "SmartShip", put a fully integrated control system on an Aegis Cruiser. The skipper of the ship could navigate from anywhere on the 550' ship with a wireless laptop, could even start/stop engines, generators, etc. Integrated the Electrical/Propulsion/Navigation/DC systems. Pretty neat. We put it on the cruiser in 16 weeks. The Navy took the program over and it took them over a year to do the next one and it didn't work as well....Oh well... :disgust

I fould that with the overlay function (on a 27" color touch screen no less) was a great thing to help you resolve what radar contacts really were! Ships don't show up on a chart but land masses/marks, etc do. Also helps you learn what a radar return is!

Go for the overlay, you'll like it. More screens are good too, Bob's right!
