Rated 3 out of 5 by 6pounder adapter cables
This product is a great improvement over the lgc2000 I had. However no one told me I would need an adapter cable for my older unit. So if you are looking to purchase the LGC4000 I would suggest you look on the lowrance website to see if your unit requires a cable to use the LGC4000

Rated 5 out of 5 by swimjig 4000 worked as advertised
Although my HDS-10 Gen2 internal antennas worked very well, I added two 4000 external antennas. They really helped while I was fishing isolated, offshore waypoints. I prefer to fish without marking places with buoys. Without the 4000s, my map would rotate some (loss of direction) when holding a position with the trolling motor, making it hard to know where to cast to the waypoint. The more frequent update rate of the 4000s eliminated the slight direction loss. Now I don't have to mark waypoints with buoys.

Rated 5 out of 5 by spee08 just what it took
My gps was constantly dropping its signal. After installing the remote unit it has never happened again.
