Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Plug and play. Works great with helix 9

Great Product!

Kept map from rotating on Humminbird GPS. Worked as expected

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.

I have a one year old Humminbird 898 combo GPS depth finder unit on my boat. I also have the I Pilot option which will not work without the GPS and Lake master map card. My antenna stopped working after only 25 hours and I contacted Humminbird tech. They immediately replaced the GPS receiver. Another 10 or so hours later I had the same problem again and again got hold of tech support. They suggested I send in my antenna, transducer and instrument for testing and gave me a return number. I went back out fishing with my wife and her friend and the unit started working again. I checked on the price of another GPS receiver and Amazon beat everyone, Humminbird included. Now I have a spare. Lots of reviews on line showing Im not the only person experiencing this GPS receiver defect. I love my unit when it works.

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.

I mounted this unit on the rear deck and turned on the Humminbird 798 hd si. All I can say is wow....

works great

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