Seaview AM18M1 18" Mount Vertical Requires Plate

The Seaview AM18M1 18" Mount Vertical is purpose-built for anglers and boaters who demand rock-solid electronics positioning on the helm. Whether you're running a center console, open boat, or tower setup, this vertical mount delivers the adjustability and stability needed to keep your fishfinder, GPS, or multifunction display exactly where you need it—without drift or vibration even in heavy seas. The 18-inch vertical extension positions your display at optimal eye level, reducing fatigue during long days on the water and improving sight line clarity through polarized sunglasses.

This mount utilizes a robust vertical rail design with precision-engineered clamping hardware that resists corrosion and mechanical loosening inherent to marine environments. The AM18M1 requires a compatible mounting plate—a modular approach that allows you to upgrade or swap displays without replacing the entire assembly. At 11 pounds, it's engineered with sufficient structural rigidity to support transducers, antennas, and display weight without sagging, while its vertical orientation minimizes wind resistance compared to horizontal mounts and reduces glare interference that plagues waterfront installations.

Boaters transitioning from older fixed-mount systems appreciate the flexibility this vertical configuration provides for future electronics upgrades. Installation is straightforward for anyone familiar with basic marine wiring and fastening practices; the mount accepts standard rail-compatible plates, making it compatible with most major fishfinder and chartplotter display housings. Serious anglers running twin engines or split-screen sonar configurations frequently employ the AM18M1 to achieve the elevated, unobstructed positioning that transforms how you read structure, thermoclines, and fish activity below the keel.
