BRCOVAN 1" Ball Fish Finder Mount - Universal 6061-T6 Aluminum Plate, 20 Pre-Drilled Holes

BRCOVAN’s 1" Ball Fish Finder Mount is a universal marine electronic plate that pairs a durable 6061-T6 aluminum rectangle with a B-size 1" TPU over-molded ball for secure, adjustable mounting of fishfinders, chartplotters and marine electronics.

This universal mounting plate is built for anglers and boaters who need a compact, corrosion-resistant platform to attach a wide range of marine electronics. The 6.25" x 2" anodized aluminum plate includes 20 pre-drilled holes to accommodate many popular devices, while the TPU-covered 1" ball gives slip-resistant compatibility with BRCOVAN B-size arms and other 1" ball mounting systems. It balances strength, low weight and easy adjustability for installations on consoles, rails or flat surfaces.

Which devices will fit this 1" ball mounting plate?

The plate is designed as a universal interface for many GPS chartplotters, fishfinders and radios. It often aligns with common screw patterns, and the 20 pre-drilled holes increase the chance of a direct fit for popular models.

• Compatible with Lowrance HDS Carbon 7, HDS LIVE 7, Hook Reveal 7 and Hook Reveal 9 series.
• Works with many Humminbird and Raymarine units (see model exclusions below).
• Suitable for CB/Ham radios, gimbal brackets and other marine electronics that match the hole pattern.
• Additional drilling may be required for devices with non-standard hole spacing.

How durable is the plate for marine use?

The rectangular plate is machined from 6061-T6 aluminum and finished with a hard anodized surface to resist corrosion, scuffs and saltwater exposure. The TPU over-molded ball adds impact cushioning and slip resistance, helping the mount hold steady in rough conditions without scratching the ball or device base.

• 6061-T6 aluminum for high strength-to-weight ratio and corrosion tolerance.
• III-grade hard anodized finish for improved surface hardness and endurance.
• TPU over-molded ball head for wear resistance and secure grip.
• CNC machining for precise flatness and reliable hole alignment.

How simple is installation and adjustment?

Installation is straightforward: position the plate, use the pre-drilled holes to attach your device, and connect to any B-size 1" double-socket arm. The standard 1" ball interface allows quick angle changes and tightening for repeatable positioning on busy boats.

• 20 pre-drilled holes cover many mounting patterns to minimize drilling needs.
• Pairs with BRCOVAN B-size 1" double-socket arms and other 1" ball arms.
• Works on flat consoles, bulkheads or rail adapters when secured properly.
• May require extra holes for non-standard electronics—drilling is supported.

Are there compatibility limits or important notes?

While the plate is broadly compatible, certain models and sizes are excluded or may require modification. Check device hole patterns and verify clearances before final mounting to avoid interference with connectors or housings.

• Not compatible with some Humminbird Helix and Solix models listed by the manufacturer.
• Designed for devices that accept a 1" swivel ball mounting pattern.
• May need custom drilling for atypical electronic housings or proprietary mounts.
• Ideal when paired with BRCOVAN arms for full compatibility and best stability.

Who is this for: This mounting plate suits recreational anglers, small commercial operators and DIY boat owners who want a compact, corrosion-resistant, and adjustable mounting solution for fishfinders, chartplotters and marine radios. It is especially useful for users who value a low-profile footprint and the ability to pair with standard 1" ball arms; technicians and installers who may need to drill additional holes will appreciate the flexible design and robust materials.
