Humminbird AS GPS HS Precision GPS Antenna w/Heading Sensor

Enhance your on-water navigation with the Humminbird AS GPS HS, a compact powerhouse that combines pinpoint GPS accuracy with reliable heading detection. Designed for serious anglers and boaters, this antenna delivers position fixes within 2.5 meters and a built-in fluxgate compass for steady boat orientation—perfect for staying locked on structure even when your vessel is stationary.

Why Choose the AS GPS HS for Superior Boat Control?

Imagine drifting over a hot bite spot, knowing exactly which way your bow is pointing relative to the map. The integrated heading sensor feeds real-time direction data to your Humminbird display, stabilizing charts and eliminating guesswork. This is especially game-changing with 360 Imaging, where you can drop precise waypoints anywhere on-screen for spot-on returns to productive areas.

Crafted for marine environments, its rugged build withstands spray, vibration, and rough seas. Mount it easily on a 1-inch-14 threaded stem (stem sold separately), and the 20-foot cable gives you flexible routing options from helm to antenna location.

Key Features That Set It Apart

• High-Precision GPS: Locks in locations fast and holds them steady, ideal for marking reefs, wrecks, or fish-holding humps.
• Fluxgate Heading Sensor: Provides compass-like accuracy without external interference, ensuring charts rotate correctly to match your view.
• Compact Design: Just 3.25 inches in diameter and 1.5 inches high—sleek enough for any console or arch.
• Enhanced Waypoint Marking: Pairs seamlessly with 360 Imaging for drag-and-drop precision, boosting your catch rates on repeat trips.
• Software Compatibility: Requires version 6.570 or newer on supported units for full functionality.

Seamless Integration with Top Humminbird Models

This antenna shines across a wide range of Humminbird fishfinders and chartplotters. It works out-of-the-box with HELIX 12, 10, 9, 8, and 7 G2N/G3N series, plus MEGA 360 and 360 Imaging setups. Older ionics like 859ci HD, 899ci HD SI, 959ci HD, 999ci HD SI, 1159ci HD, and 1199ci HD SI combos are fully supported too.

For SOLIX and ONIX series, grab the AS GPS NMEA adapter or cable. APEX users need the dedicated AS GPS adapter. Note: It skips InterLink compatibility, focusing on direct, robust connections.

Installation Tips for Peak Performance

Position the antenna high and away from metal obstructions or other electronics to minimize signal interference. North alignment during setup is key—calibrate the heading sensor in calm water for best results. Once connected, your display instantly reflects stabilized heading lines, making trolling patterns and dock approaches intuitive.

Pro tip: Pair it with AutoChart Live for dynamic mapping that incorporates your precise track data, turning every outing into a custom lake chart.

Real-World Benefits for Anglers

Fishermen swear by the AS GPS HS for its role in competitive scenarios. When structure fishing, the heading overlay helps you parallel edges perfectly. In windy conditions, it counters swing-induced disorientation, keeping you on the money line. Kayak anglers appreciate its low profile, while offshore boaters value the reliable fixes for long runs.

Backed by a one-year limited warranty, it's a smart upgrade that pays off in tighter lines and bigger fish.
