Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Kept map from rotating on Humminbird GPS. Worked as expected

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

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.

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

Bought this unit to increase the accuracy of my Solix 12 position information. Mounted it on a $25 Ram D VHF antenna mount (perfect thread match) about 18” in front of the motor on my bass boat. No interference problems. Am using it with the Solix Live Chart function to map the bottom of a historically significant bay in my area. Allows me to run parallel track with close spacing to insure full bottom coverage of my DI and SI collections.

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

As discribed

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

works great
