Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Authentic Humminbird product. Excellent price

Works as advertised. Great price.

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.

I liked the directional feature on my Hummingbird as a result of this antenna, easy to install, easy to place

Greatly improved the accuracy on our Helix 9, when we are stopped, the boat stays pointed in the correct direction on the display

Happy Husband, Happy... life?wife?

Makes find location easy.

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

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