Garmin Channel-Change Knob f/GHS™ 11/11i

The Garmin Channel-Change Knob for GHS™ 11/11i is an essential replacement control designed for serious anglers and marine electronics users who require reliable performance on the water. This dedicated knob provides tactile, fast access to channel selection on your Garmin fish finder, a function that is crucial during a day of fishing as you adjust frequency and sonar views to adapt to changing conditions.

Engineered for smooth, positive rotation without resistance or play, this channel-change knob ensures precise navigation of sonar inputs under all conditions. Its robust design withstands repeated turning cycles, making it essential for toggling between frequency bands and zoom levels during extended fishing sessions. Built to OEM specifications, it integrates seamlessly with the GHS™ 11 and 11i systems, maintaining the expected tactile feedback and mechanical reliability.

Boat owners upgrading from damaged or sticky original components will notice an immediate improvement in user interface responsiveness. The compact profile of the knob fits naturally under your thumb or fingertip, allowing for one-handed operation, which is critical when managing the wheel or handling tackle. This part is ideal for restoration projects on aging GHS™ 11/11i units, enhancing the overall user experience.
