Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

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

Perfect, thank you!

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

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

Vastly improved the accuracy of my Helix 10 Mega. Great Product.

Seems to be extremely accurate and starts up and finds satellites very quickly. The heading sensor is nice so when I have the map set to heading-up it doesnt spin when Im not moving.

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

works great

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

Authentic Humminbird product. Excellent price
