Millennium Marine Double Face Mount – Heavy Duty Dual Mount
Best for: boaters needing a rugged, height-adjustable two-fish-finder setup. The anodized aluminum frame withstands harsh environments and includes heavy-duty stainless-steel hardware for secure mounting. The telescoping riser (18–24 inches) keeps the displays at ergonomic eye level, while a base that swivels 180 degrees and a monitor plate that swivels 350 degrees offer broad viewing angles. Caution: installation requires careful alignment to avoid interference with cockpit hardware.
Millennium Marine Double Face Mount – Version 2
Best for: anglers needing consistent dual-display access with flexible height and angles. This variant repeats the heavy-duty anodized aluminum frame and 18–24 inch telescoping riser, ensuring both screens remain visible in varying sea states. The 350° monitor plate swivel supports multi-helm viewing. Caution: ensure mounting plate compatibility with your two chosen displays, and confirm clearance from other electronics on the boat.
Str8 Up Mounts Dual Plate – Wide Universal Fit
Best for: buyers needing a universal dual-mount that supports most major brands. The 12 x 10 inch frame with reinforced center bend accommodates two fish finders side by side. Caution: the setup is best when units share similar depths and mounting patterns, to avoid uneven load distribution. The product lists adjustable 12 x 10 inch frame dimensions, which may require measuring your displays beforehand.
WINDFRD Aluminum Dual-Screen Mount
Best for: fishers needing a heavy-duty, corrosion-resistant dual-mount with independent, adjustable arms. The mount supports two displays with up to 110 lbs static load and 22 lbs dynamic load. It provides smooth 360° rotation and tool-free locking knobs for reliable positioning. Caution: recommended for units under 10″ to minimize potential screen interference; verify weight of each unit before mounting.
Baldwin Iron Works Universal Dual Mount (USA Made)
Best for: buyers seeking a versatile, USA-made dual graph mount with universal bolt patterns. The unit features adjustable 45-degree tilting and is built from 3/16 aluminum with stainless hardware, offering robust compatibility with Garmin, Lowrance, Humminbird, and more. Caution: confirm exact bolt patterns for your devices, as universal compatibility can vary by model.
Baldwin Iron Works Dual Mount – 9″ Graphs
Best for: users needing a compact dual-graph setup with a 5.5″ height. The mount uses 3/16 aluminum with stainless hardware and a universal bolt pattern. Caution: ensure your displays fit within the 5.5″ height constraint and that the bolt pattern matches your units for secure mounting.
Buying Guide: How To Choose A Double Fish Finder Mount
- Display size and weight: Verify both units’ dimensions and weight to ensure the mount can handle the load without sagging or excessive movement.
- Mounting pattern compatibility: Look for universal bolt patterns or specific compatibility with your brands (Garmin, Lowrance, Humminbird, etc.).
- Adjustability: Consider height range, swivel degrees, and whether independent arms are needed for each screen.
- Materials and corrosion resistance: Marine-grade aluminum and stainless hardware perform better in saltwater environments.
- Installation space: Measure console depth and available width to avoid crowding or interference with controls and seating.
- Ease of installation: Some mounts offer tool-free adjustments, while others require more precise drilling and aligning.
What should I consider if I want a dual-mount on a small boat?
On smaller boats, prioritize compact frames, compatible bolt patterns, and minimal protrusion to keep spaces navigable. Choose mounts with adjustable heights and tight locking mechanisms to prevent vibration during waves.
Are universal dual mounts safe for heavier screens?
Universal mounts vary in weight capacity. Always verify the total weight of both displays and confirm the product’s static and dynamic load specifications before mounting.
Can these mounts adapt to future upgrades?
Many dual mounts use universal plates and adjustable arms, allowing newer models to fit with adapters or updated mounting plates. Check compatibility notes from the manufacturer.
Which brands are most commonly supported?
Garmin, Lowrance, Humminbird, and Raymarine are frequently supported. Always confirm bolt patterns and VESA-like standards if applicable for your devices.
What installation challenges might I face?
Common challenges include limited helm space, clearance issues with steering wheels or throttles, and ensuring cables have slack without obstructing moving parts. Plan cable routing before final tightening.
What is the best practice for dual-arms versus single-arm designs?
Dual-arm designs offer independent positioning, which is helpful for viewing from different helm angles. Single-arm dual-plate setups save space but may be less flexible for simultaneous viewing.
Is a higher price an indicator of quality?
Higher price often correlates with heavier materials, corrosion resistance, and more flexible adjustments. However, always verify actual features and load ratings rather than price alone.
