Marine GPS Accessories $43.99
★★★★★ 4.8/5 39 ratings A compact NMEA 2000 dual-device starter kit designed to help you expand an existing NMEA 2000 backbone and add a second connection with color-coded components.

Marine GPS Accessories $32.99
★★★★★ 4.6/5 49 ratings An aluminum alloy fish finder lock set designed to help keep your Garmin, Lowrance, or Humminbird unit secured to its gimbal mount. Best for boat owners who want an extra layer of theft and movement protection, with the main tradeoff being that installation may take some patience and locking value depends on your specific mount setup.
Radar Systems $80.71
★★★★★ 4.8/5 20 ratings The Garmin Radar Power Cable is a long, threaded power lead designed to deliver consistent DC power to compatible Garmin radar units, including several GMR xHD and radome models. It’s built for secure connections and extended marine use, but it is only the right fit if your radar model matches the supported list and your install calls for a 48-foot cable run.
Marine Speakers $115
★★★★★ 4.3/5 14 ratings STUDIOFINIX’s 8-inch wired marine speakers are designed for outdoor, weather-resistant setups, with ice-blue LED accent lighting and a straightforward screw-on mounting approach. Buyers who installed them for boats, ATVs, and similar off-road or lakeside use report solid outdoor volume and clear audio for the size, though the strongest caveat is the limited clarity around true water exposure ratings and the value versus price.
Marine Two-Way Radios $172
★★★★★ 5/5 8 ratings The Icom M25EVO is a compact, lightweight floating VHF handheld built for marine use, with IPX7 water resistance, USB-C charging, and an Eco Mode battery extension. It is best for boaters and kayakers who want an easy-to-grab backup radio with clear handling in wet conditions, with the main caveat that buyer feedback is limited and pairing a use case with its typical range will matter.
Radar Systems $46.99
★★★★★ 3.3/5 29 ratings The Davis Emergency Deluxe Radar Reflector is a compact, lightweight marine radar reflector designed to improve your chances of being seen in fog or low-visibility conditions. It folds flat for storage and opens quickly to an 11.5-inch diameter, but buyer feedback suggests it is relatively flimsy and best treated as an emergency add-on rather than a long-term, heavy-duty fixture.
Radar Systems $124
★★★★★ 3.4/5 11 ratings The Davis Echomastrer Standard Radar Reflector is a marine radar reflector built around a 12-1/2 inch heavy-gauge aluminum plate design with a sizable reflective surface. It is designed for straightforward assembly and use, but buyer-review evidence is limited, and some customers report missing parts or mounting-hardware confusion, so it is smart to confirm what is included before purchasing.
Marine GPS Accessories $25.98
★★★★★ 4.6/5 52 ratings A purpose-built 3D-printed holder designed to fit Minn Kota Bluetooth remotes, keeping your iPilot remote secure and reachable. Buyers consistently mention a “perfect fit” and secure storage, with an easy slide-in design, but the listing is for the holder only and the remote is not included.
Marine GPS Accessories $25.98
★★★★★ 4.8/5 51 ratings A purpose-built 3D-printed holder for the Minn Kota i-Pilot Advanced GPS remote, made from carbon-fiber-infused PETG-CF.

Marine Subwoofers $400
★★★★★ 5/5 3 ratings The KICKER 51MWF104 is a 10-inch free-air marine subwoofer built for saltwater-style conditions, with weather-sealed construction and a TPE surround. It’s a strong pick if you want louder, deeper bass without adding a separate enclosure, but you’ll need to confirm your mounting space, wiring plan, and LED controller compatibility if you want RGBW color-changing effects.
Radar Systems $159
★★★★★ 5/5 7 ratings A 5 meter Raymarine digital radar cable with Raynet connector designed to connect compatible marine radar systems. It is a straightforward, job-specific accessory, and the limited review history is strongly positive for working reliably once installed.
Marine Amplifiers $135
★★★★★ 3.6/5 8 ratings The Rockville Krypton MF3 is a 4-channel marine amplifier designed for saltwater conditions, with a conformal-coated PCB, rustproof aluminum heat sink, and stainless steel hardware. It includes built-in PA functionality with a talk-over feature and offers an adjustable 12dB/octave crossover for different speaker and subwoofer setups, but available buyer evidence is limited and there is at least one report of noise issues after a couple months.
Fish Finders & Depth Finders $54.99
★★★★★ 4.8/5 19 ratings This 5-inch IPS underwater fishing camera pairs a 1000TVL (1080p) sensor with a wide viewing angle, infrared night mode, and a 65 ft cable for ice, river, and boat fishing. It’s aimed at anglers who want a clear live view and longer sessions, but buyers should consider the cable depth, battery runtime, and that it’s not a smart device.
Marine GPS Accessories $19.90
★★★★★ 4.6/5 49 ratings The TUSITA tilt/swivel gimbal mount bracket with knobs is made to fit select Garmin STRIKER, STRIKER Vivid, and ECHOMAP UHD2 fish finder/GPS units. It’s an easy way to free up viewing angles on a bow, dash, or console, with a simple adjust-and-position setup. The main caveat to consider is cable management, since at least one buyer noted the lack of a dedicated lock plate for power and transducer cables.
Marine GPS Accessories $32.99
★★★★★ 4.4/5 26 ratings This aluminum fish finder lock set is designed to add anti-theft and sturdier mounting hardware to compatible marine units. It uses marine-grade materials and includes stainless-steel hardware for a more secure hold, but buyer-fit depends heavily on correct alignment and the exact lock hardware dimensions for your specific model.
Marine GPS Accessories $22.99
★★★★★ 4.7/5 37 ratings A 20-foot RJ45 male-to-male marine Ethernet cable designed to replace Garmin part 010-10551-00 and connect compatible chartplotters, GPS radars, fish finders, and the GMS 10 expander.

Radar Systems $260
★★★★★ 5/5 3 ratings The APT-150-01 is a marine-grade aluminum radar mount (6-inch / 150mm) built to help keep your radar steady on a powerboat, with an aft-leaning, 25-degree rake for better sightlines.

★★★★★ 4.4/5 7 ratings The Rockville RM-PREMIUM104 is a 10-inch white marine subwoofer built around a free-air design (no enclosure needed), dual 4-ohm voice coils, and a polycarbonate cone for harsher on-water conditions.

Radar Systems $127
★★★★★ 4/5 6 ratings The Raymarine Quantum Radar Data Cable (A80275) is a 10 meter multicolored cable designed for Quantum radar setups. It is a good fit when you need a longer run, but buyer feedback is limited and one report suggests possible connection failure after time, so plan for careful routing and installation.
Marine Antennas $89.94
★★★★★ 4.4/5 7 ratings The LocMarine LM-SMINI-FX is a marine-grade fixed mount kit designed to attach a Starlink Mini flat dish to boats and other vessels. It includes the flat-dish base, the pipe adapter, and mounting hardware for a straightforward install, with buyer feedback pointing to solid build quality and an easy setup.

Marine Subwoofers $600
★★★★★ 5/5 1 ratings The Rockford Fosgate M2D4-12IB is a 12-inch dual-voice-coil (DVC) marine subwoofer designed for infinite baffle installs, with app-controlled multicolor RGB LED lighting. It brings 400 watts RMS (1600 watts peak) power handling, an impedance switching feature, and IP67-rated marine protection, making it a strong pick for buyers who want both bass and customizable lighting. The main tradeoff is that LED control and color effects depend on Color Optix controller accessories sold separately.
Marine GPS Accessories $19.99
★★★★★ 4.4/5 26 ratings This Holicfun kit adds two practical upgrades for Garmin Striker Plus 4 and Striker Vivid 4cv owners: an anti-glare sun visor for better screen readability in bright conditions, and a protective screen cover to keep the display area clean from scratches and dust during transport. Expect a custom fit, quick screw-on installation, and the option to use the pieces separately or together, with the main tradeoff being that the protection is accessory-level and relies on durable ABS plastic.
Marine Antennas $98.36
★★★★★ 5/5 5 ratings The Shakespeae 5206-N is an economical 8-foot VHF marine antenna built for solid short-to-midrange communications where range is not the top priority. It uses a nylon ferrule, includes 15 feet of RG-58 cable with a PL-259 connector, and is designed for a vertical, omni-directional marine setup, with a typical SWR around 1.5:1 at 156.8 MHz.
Marine Two-Way Radios $240
★★★★★ 5/5 2 ratings The global-ptt P0 is a cellular PoC (push-to-talk over 4G LTE) two-way radio set built for nationwide communication without pairing or repeater setups. It’s IP67 waterproof and designed to float, with loud, noise-suppressed audio and a rechargeable, rugged form factor, but it depends on LTE coverage and a yearly SIM service model.
Marine Subwoofers $440
★★★★★ 5/5 1 ratings Rockford Fosgate’s M2D2-10IB-G2 is a 10-inch DVC 2-ohm marine subwoofer designed specifically for infinite baffle installs (no standard enclosure).

Marine Subwoofers $191
★★★★★ 5/5 2 ratings Garmin Fusion Signature Series 3i 12-inch marine subwoofers are built for low-frequency impact on the water, with an IP65 rated, marinized design intended for pairing with Fusion marine stereos and compatible amplifiers.

Marine GPS Accessories $5.69
★★★★★ 4.3/5 56 ratings These SYGGDERS suction cups come as a 10-pack replacement set for specific radar detector suction-based mounting setups. Reviewers report they press on securely and hold up in hot weather, but fit can be mount-specific, with at least one case where a certain mount was too loose.
