The Garmin 6FT marine network cable uses RJ45 connectors on both ends with screw collars and a hole plug, designed to connect compatible Garmin chartplotters and marine network devices at 72 inches. It’s a good fit if you want the intended Garmin cabling approach, but it costs more than generic Ethernet cables and only makes sense for Garmin networking setups that accept this style of connection.
A tall, drill-down fish finder mount built for better viewing angles without hunching. The C-size ball-and-socket design delivers wide adjustability and easy compatibility with many Garmin, Lowrance, and most Humminbird models (with a few Helix models excluded), but the long extension is best paired with up to 9-inch screens.
A compact, marine-grade NMEA 2000 4-port tee connector that expands a backbone to add up to four displays, sensors, or other N2k components. It features corrosion-resistant gold-plated contacts and is rated IP67 for submersion resistance, with buyer feedback pointing to solid fit and connectivity for common Garmin, Lowrance, Simrad, B&G, and Navico setups.
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). It’s designed for saltwater use with marine-grade aluminum and stainless hardware, but buyers should plan to use their own higher-quality mounting hardware if their dash or deck needs more than the included screws.
The VAUBORTTI aluminum fish finder mount uses a marine-grade aluminum body, a 14.76-inch dual-rod extended arm, and a 1.5-inch TPU ball for adjustable positioning and steadier support. It is a solid fit for compatible RAM-style C-size (1.5 inch) setups, but it may struggle with heavier fish finder units if the load pushes the mount’s joint mechanics.
A custom-fit anti-glare sun visor designed specifically for Garmin Striker 4-series fish finders. It helps cut reflection so you can read the screen more easily in bright daylight, with quick tool-free installation, but the fit may feel a bit loose for some users.
A short, NMEA 2000 certified 1/2 meter (19 inch) backbone, drop, or extension cable for wiring sensors and displays into an N2K network. It uses shielded cable for reduced interference, 5-pin NMEA 2000 connectors with gold-plated contacts, and an IP67 submersion rating for marine use.
A 15-foot NMEA 2000 backbone/drop/extension cable for building or extending a marine N2K network. It features 5-pin connectors on both ends, gold-plated contacts for corrosion resistance, shielded conductors for reduced interference, and an IP67 waterproof test standard.
The VAUBORTTI marine fish finder mount is a rail-track compatible bracket built from one-piece die-cast aluminum with an electrostatic powder coat for corrosion resistance. It uses a 1.5-inch TPU ball and an oversized wing-style adjustment knob for easier positioning, and it supports popular Garmin and Lowrance units via AMPS-style hole patterns and a C-size (1.5-inch) arm system.
