The mount is built from powder-coated marine-grade aluminum and corrosion-resistant composites, and that construction is the single biggest reason to buy for anyone mounting a fishfinder or chartplotter up to about 9 in. The included 18.3 in double-socket arm and robust AMPS base make installation versatile, and customers will appreciate the secure hold and easy angle adjustments once installed.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eExtra-long double arm:\u003c\/strong\u003e The 18.3 in C size arm replaces multiple connectors to provide reach without sacrificing rigidity when positioned correctly.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMarine-grade construction:\u003c\/strong\u003e Powder-coated aluminum and corrosion-resistant composite materials give lasting strength in saltwater environments.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSalt spray tested hardware:\u003c\/strong\u003e Stainless steel bolts and springs plus a cast single-piece aluminum body resist high salt corrosion for thousands of hours.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e The rectangle plate and AMPS hole pattern match many GPS and fishfinder units from major manufacturers and standard mounting systems.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eTwo ball joints:\u003c\/strong\u003e Dual ball and socket adjustments offer near-infinite tilt and rotation options for optimal viewing angles and 360 rotation.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eComprehensive fasteners:\u003c\/strong\u003e Supplies include four sets of 316 marine grade stainless steel machine screws, lock nuts and sheet metal screws for a secure install.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis mount is geared toward recreational and semi-pro anglers who use medium to large chartplotters and fishfinders up to around 9 in and who need a long reach arm that still locks solidly in place.
