Marine GPS Accessories $157
★★★★★ 4.7/5 537 ratings The Minn Kota 1866550 Bluetooth i-Pilot System Remote adds a practical second control point for Bluetooth-enabled i-Pilot setups. It’s built for everyday deck use with a larger LCD, instant status feedback, and an easy battery compartment, but it only works with i-Pilot systems that support Bluetooth (2017+), so compatibility matters.
Marine GPS Accessories $132
★★★★★ 4.5/5 567 ratings The MotorGuide 8M0092071 Xi series Pinpoint GPS navigation remote is a targeted replacement remote for Xi3 and Xi5 trolling motors, adding convenient steering and anchoring controls plus GPS features like heading lock, jog, and route record/playback. It’s a straightforward swap for anglers who need their remote back in action, but it only fits the Xi3/Xi5 ecosystem and uses two AAA batteries.
Marine GPS Accessories $179
★★★★★ 4.4/5 323 ratings C-MAP Reveal adds richer shading, detailed vector charts, and advanced bathymetry layers to compatible Marine GPS chartplotters using a microSD card.

Marine GPS Accessories $160
★★★★★ 4.7/5 182 ratings The Garmin Three-Axis Compass Heading Sensor adds more stable, more accurate heading for compatible Garmin chartplotters through a plug-and-play NMEA 2000 connection.

Marine GPS Accessories $13.90
★★★★★ 4.7/5 1,855 ratings The TUSITA silicone sun cover is designed to protect specific Garmin fishfinder/chartplotter models by shielding the main screen from sun, scratches, and everyday elements. Based on buyer feedback, the standout feature is the snug, well-aligned fit, with a thicker soft cover that stays in place better than some rigid or thinner alternatives.

It comes preloaded with “Zero Lines” shoreline data across the U.S. and Canada and lets compatible Humminbird units record depth and bottom detail directly to the card for later use and sharing across multiple fish finders. Best for anglers who plan to build and display custom lake maps, with the main tradeoff being that it adds cost if you only want basic navigation.
Marine GPS Accessories $28.50
★★★★★ 4.8/5 623 ratings The Humminbird GM H7 gimbal mount is a replacement kit made to fit Humminbird HELIX 7 fish finder units. It’s aimed at boaters who need a secure, adjustable tilt mount and the correct hardware to get back to using their screen confidently.

Marine GPS Accessories $52.99
★★★★★ 4.7/5 101 ratings A heavy-duty, near-infinite adjustable ball-and-socket mount built for Hummingbird Helix 5 and Helix 7 series units (and other 1.5” C-size compatible adapters).
