Edson Stainless GPS Mount 3" Mounting Base 1-1.25" Rail

The Edson Stainless GPS Mount 3" Mounting Base with 1-1.25" Rail secures hand-held navigation units on steering pedestals and rail-mounted platforms where GPS accessibility and protection from water spray, salt air, and UV exposure are operational priorities. Constructed from investment-cast 316 stainless steel with a marine-grade polymer base, this GPS mount combines corrosion resistance with secure positioning for extended offshore operations, coastal patrols, and high-moisture environments where standard aluminum or painted steel mounts fail prematurely.

The 3-inch mounting base accommodates rail widths from 1 to 1.25 inches, standard on most modern vessel pedestal guards and tactical rail systems. Pre-drilled to interface with Garmin GPS swivel mounts, the arm accepts most round GPS brackets up to 5 inches in diameter, including Magellan and other Garmin units. The highly polished 316 stainless arm prevents corrosion in saltwater and high-humidity conditions where standard finishes corrode within months. The black polymer base resists UV degradation and requires no routine maintenance—a critical advantage on vessels or equipment stored outdoors year-round.

This mount serves maritime operations, coastal law enforcement, offshore research platforms, and tactical watercraft where reliable GPS positioning and durable hardware construction directly impact mission success. Operators in salt-spray environments will recognize the value of investment-cast stainless over sheet-metal alternatives—material thickness and homogenous composition prevent stress cracking and galvanic corrosion. The rigid pedestal mounting eliminates vibration-induced GPS signal loss common with lighter arm designs.

Edson Marine specializes in stainless hardware for marine applications where equipment longevity and corrosion resistance directly reduce lifecycle costs. This GPS mount represents the mid-range option in pedestal-mounted navigation systems—more robust than polymer-only solutions, more cost-effective than full-titanium assemblies, and properly specified for professional watercraft and tactical platforms operating in demanding environments.
