Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Works great with my Helix 7 on my trolling motor keeping my heading on point while I move direction with my trolling motor.

I bought this antenna to replace the original gsr50 that came with my unit. It is hands down a better antenna.

Works as advertised. Installed up front with my Helix 12 SI. I now have a better gps signal and a stationary heading indicator. Follow the online video on how to program your Helix to use this external sensor in lieu of the internal sensor in the Helix head unit.

easy to install, works flawlessly and the best price I could find with fast shipping. What more cold you ask for!

This receiver is great for slow speed trolling and other slow speed use. For over 10 mph the receiver that comes with your unit works well.

Authentic Humminbird product. Excellent price

Be sure to try out the install location on your boat before drilling holes. Since this unit has a magnetic compass, any motor, speaker or magnet will throw it off.

Bought this unit to increase the accuracy of my Solix 12 position information. Mounted it on a $25 Ram D VHF antenna mount (perfect thread match) about 18” in front of the motor on my bass boat. No interference problems. Am using it with the Solix Live Chart function to map the bottom of a historically significant bay in my area. Allows me to run parallel track with close spacing to insure full bottom coverage of my DI and SI collections.

works

Great heading sensor and GPS. Helps show position when not moving.
