Humminbird AS GPS HS Precision GPS Receiver with Heading Sensor,

Works as advertised. Great price.

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.

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.
