BRCOVAN 1" Ball Fish Finder Mount — Universal Marine Electronic Plate, 6061‑T6 Anodized, 20‑Hole Pattern

The BRCOVAN 1" Ball Fish Finder Mount is a universal marine electronic plate that provides a stable, corrosion-resistant, quick-swap mounting solution for fishfinders, chartplotters and other boat electronics.

Built from 6061-T6 aluminum with a hard-anodized finish and a TPU over-molded B-size 1" ball, this rectangular plate offers broad compatibility and rugged durability for demanding saltwater and freshwater conditions. The plate's 6.25" x 2" footprint and 20 pre-drilled holes accommodate many popular devices and mounting patterns, letting you attach GPS chartplotters, fishfinders, radios and more using BRCOVAN 1" ball arm systems or other 1-inch swivel ball mounts.

Which devices will this mount work with?

The plate is designed to match a wide range of marine electronics from major brands thanks to its multiple hole patterns. It specifically lists compatibility with several Lowrance, Humminbird and Raymarine models, though some devices may still require minor drilling or adapter plates for a perfect fit.

• Pre-drilled 20-hole pattern fits many chartplotters and fishfinders
• Compatible with Lowrance HDS Carbon, HDS LIVE, Hook Reveal series (7" and 9" where noted)
• Works with many Humminbird and Raymarine units; check manufacturer hole patterns before installation
• Accepts accessories such as CB radios, Ham radios and gimbal brackets

How durable and weather-resistant is the plate?

The rectangular plate is CNC-machined from 6061-T6 aluminum and finished with a grade III hard anodize to resist corrosion and abrasion in marine environments. The TPU over-molded ball adds impact resistance and anti-slip properties where the ball meets the socket, reducing wear from repeated adjustments.

• 6061-T6 aluminum body for high strength-to-weight ratio
• Grade III hard anodized surface for superior corrosion resistance
• TPU over-molded B-size 1" ball for wear resistance and secure seating
• Precision CNC machining for consistent hole alignment and flatness

Can I use this plate with other 1" ball arm systems or mounts?

Yes — the 1" B-size ball is compatible with BRCOVAN double-socket arms and most other arms and mounts that accept a 1-inch swivel ball. If your mounting solution uses a different ball size or non-swivel pattern, an adapter or alternate plate may be required.

• Fits BRCOVAN B-size 1" double-socket arms directly
• Works with third-party mounts using the 1" ball standard
• May require adapters for non-standard socket or plate systems
• Additional drilling can customize fit for unusual devices

What should I expect during installation and customization?

Installation is straightforward for devices that match the pre-drilled pattern: fasten the unit to the plate, then secure the plate to a compatible arm or mounting surface. The plate offers a universal layout, but in some cases you may need to drill extra holes or use spacers to align with specific electronics.

• Mount device to plate using the existing 20 hole options
• Attach plate ball to a BRCOVAN 1" double-socket arm or compatible mount
• Drill additional holes if needed for uncommon hole patterns
• Use stainless hardware and marine-grade sealant for best corrosion protection

Who is this for: The BRCOVAN 1" Ball Fish Finder Mount suits anglers, boat builders and marine electronics installers who want a versatile, heavy-duty mounting plate for chartplotters, fishfinders and other marine devices. It’s aimed at users who need a reliable, corrosion-resistant plate that pairs with 1" ball mounting systems and who are comfortable making minor customizations when a device’s holes don’t align perfectly.
