Scotty 0163 Ball-Mount Fish Finder and Universal Mounting Plate

The Scotty 0163 uses a 1.5-inch ball to deliver solid clamping and full motion for larger displays, specifically designed to accept 7–9″ fish finders. This mount is ideal for boaters who want a versatile ball-mount setup that can consistently hold a heavier screen while allowing easy tilting and turning. Best for anglers using mid-to-large depth finders on a traditional ball-based system.
Best for: boaters with 7–9″ screens who need strong clamping and smooth movement. Choose this if your fish finder is on the larger end of the spectrum and you prefer a ball-style mounting head.
Caution: Larger accessories require careful tightening to avoid drift in rough seas; ensure the ball and top plate are aligned during installation.
DepthTrax 2B Boat Mount In Dash Digital Depth Finder

The DepthTrax 2B is built for in-dash installations, delivering depth readings on a large display at high speeds. It includes dual mount transom or glue-in transducers and is capable of through-hull mounting in fiberglass and light aluminum hulls. This option suits builders seeking integrated dashboards with clear alarms and a bright alert system for quick situational awareness. Best for: boats requiring an in-dash depth finder with robust alert capabilities.
Best for: installations where the depth reader must be flush with the dash and visible at speed. Consider this if you want a built-in radar-like depth experience with a strong alarm system.
Caution: In-dash setups may require professional routing of cables and a precise fit to prevent glare or misalignment on the display.
WINDFRD Aluminium Fish Finder & Chartplotter Mount

This heavy-duty aluminum mount supports up to 110 lbs static load and 22 lbs dynamic, making it ideal for large, rugged displays on boats that encounter constant motion. It is powder-coated for durability in saltwater environments and features a versatile base with multiple pre-drilled holes to fit Garmin, Lowrance, Humminbird and more. Best for: large, high-stability screens on saltwater craft that demand long-term corrosion resistance.
Better for: installations where a long, adjustable mounting base is advantageous for optimal line-of-sight across decks or consoles. Avoid this if your vessel requires a lighter, quick-release mount for frequent removal.
VAZESWIN Aluminum Alloy Mount with 9.1″ Arm

The VAZESWIN mount combines a 2.4″ round base with a 9.1″ long dual-socket arm and rectangular plate, compatible with a wide range of 7–12″ devices. It supports customizable positioning with a RAM-style 360° rotation capability. Best for: RAM-compatible assemblies needing a longer reach and flexible angles on medium-to-large screens.
Limitation: ensure the mounting surface can accommodate the longer arm span without obstruction or interference with other equipment.
Vadaxx Universal 360° Rotation Mount

The Vadaxx mount emphasizes universal compatibility with flat surfaces and an AMPS hole pattern, enabling easy drilling to fit Garmin and Lowrance devices. It features a dual 360° swivel ball design for flexible viewing angles. Best for: setups that require a highly adjustable, universal bracket for multiple device types on a single vessel.
Limitation: installation requires careful alignment with drill holes on the chosen surface; not ideal for plug-and-play setups where drilling is restricted.
BOSHCHEN 360° Swivel Mount Base

The BOSHCHEN mount offers dual 360° rotation with a 2.6″ base and 1.8″ swivel ball, designed for strong stability. It is compatible with a wide range of devices and emphasizes easy installation on flat surfaces, making it suitable for quick setups and flexible positioning. Best for: boats needing a robust, rotatable mount that can support various depth finders or chartplotters.
Limitation: heavier builds may affect mounting ease on smaller boats or dashboards with limited space.
Aluminum Fish Finder Mount With 1.5″ Ball, 14.76″ Arm

This VAUBORTTI mount uses marine-grade aluminum with a 1.5″ RAM-ball style interface and a long 14.76″ arm. The extended length supports hard-to-reach displays and provides a comfortable viewing angle with a stable hold. Best for: boats requiring a long reach and corrosion resistance for larger screens. Limitation: the longer arm increases the footprint and may require more deck space.
Buying Guide: Key Purchase Considerations
- Mount type: Ball-mounts suit flexibility and quick adjustment; in-dash mounts offer a sleek, integrated look; universal brackets provide maximum device compatibility.
- Material and corrosion resistance: marine-grade aluminum and stainless steel hardware endure saltwater exposure; powder coatings add protection for long-term reliability.
- Weight capacity: ensure the mount supports your depth finder’s weight and any additional accessories without strain.
- Device size compatibility: check the maximum screen size each mount supports; larger screens need sturdier clamps and longer arms.
- Installation surface: some mounts require drilling on a flat surface; others are clamp-based and may be easier to install on existing dashboards.
- Adjustability: prioritize 360° rotation or wide tilt ranges for optimal viewing from different seating positions on the boat.
- Maintenance: look for easy-clean designs and corrosion-resistant hardware to minimize wear from salt air and water spray.
Frequently Asked Questions
- What should I consider when choosing a depth finder mount for a small boat?
– Choose a lightweight, clamp-on or RAM-base mount with a compact footprint and simple adjustments to fit limited deck space. - Are In-Dash depth finder mounts better for speed and visibility?
– In-dash mounts offer a clean look and easy visibility at speed, but require careful routing of cables and a precise fit to the dash. - Do I need a universal mount or a model-specific mount?
– If you own multiple devices or may upgrade later, a universal mount provides long-term flexibility; otherwise a model-specific mount can ensure a perfect fit. - Can these mounts handle large screens (9″ or more)?
– Yes, several options, such as ball-mounts and heavy-duty aluminum mounts, are designed to support larger screens with strong clamping. - Is corrosion resistance important for saltwater boats?
– Absolutely. Marine-grade aluminum and stainless steel hardware reduce deterioration from salt spray and humidity.
