Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Kept map from rotating on Humminbird GPS. Worked as expected

Authentic Humminbird product. Excellent price

works

Well made item, works great with my GPS unit in my boat. Easy plug and play

works well - replacement for the original which is not longer available.

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.

Happy Husband, Happy... life?wife?

Works as advertised. Great price.

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

Perfect, thank you!
