Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

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

This thing is amazing. When I mark brush piles its so easy to go right back to them even at slow speeds.

Works as advertised. Great price.

AWSOME

Great Product!

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.

Husband needed an extra for his other boat and he’s happy with this purchase, works as described.

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.

Not the unit I needed.

Increases accuracy to within a few feet of pin points.
