Humminbird AS GPS HS Precision GPS Antenna with Heading Sensor - 408400-1

Excellent product,True north and my gps is no longer lagging

I purchased the Humminbird AS-GPS-HS to compliment my Mega 360 Imaging. I needed it to be able to see and mark waypoints on my Helix 9 MEGA DI+ unit. Once installed I had a boat direction heading on my GPS screen and was able to see my waypoints on my 360 Imaging screen. FANTASTIC! While I was calibrating the Heading Sensor, I decided to try to fish a previous waypoint that now appeared on the screen. First cast i caught a 19.5 bass and a 175' bass on the second cast! Why ... because i could see the point on my 360 and knew where and how far to cast! (it was a weed edge and I was 30 feet from it) Without the Heading Sensor, I would not be able to see my 500+ waypoints while I was using the Mega 360 Imaging! Absolutely a MUST HAVE!
