Overview Humminbird ICE 398ci Fishfinder GPS Combo

Humminbird ICE 398ci Fishfinder GPS Combo is a specialized portable unit built for ice fishing, combining sonar, GPS, and charting functions in a compact 3.5-inch display platform. The source data emphasizes its cold-weather setup, ICE Target Line function, and DualBeam PLUS sonar performance for vertical fishing through the ice.

This model is designed for anglers who move between holes or return to proven winter spots across a frozen lake. Internal GPS, built-in UniMap coverage, selectable sonar views, and a transducer designed specifically for ice use help it support both navigation and precise depth interpretation in a portable format.

Key Features

• Ice-specific sonar setup: Includes the XI 9 20 transducer, weighted for vertical deployment and built to work well in ice fishing conditions.
• DualBeam PLUS sonar: Provides narrow and wide cone coverage so users can balance detail with a broader search area.
• ICE Target Line and flasher-style use: Helps track lure depth and fish position more clearly when fishing vertically.
• Internal GPS and waypoint storage: Supports chartplotting, route planning, and repeat access to productive winter spots.
• SwitchFire sonar views: Lets users choose cleaner or more detailed sonar presentation depending on water conditions and clutter.

Applications

• Hole-hopping on large lakes where portable GPS and waypoints help track productive locations.
