Anti-Theft Aluminum Fish Finder Mount with Lock Knob - Short Arm

Our review of this anti-theft aluminum fish finder mount finds it aimed at anglers and boat owners who need a compact, robust mounting solution that resists saltwater and vibration. The single biggest reason to buy is its combination of military-grade construction and an anti-theft lock knob, which together deliver a secure platform for mid-size chartplotters and fishfinders while surviving harsh marine conditions. The reviewer notes the mount is deliberately compact with a 3.42' short arm, making it a practical choice for bass boats, kayaks and small center consoles where space and durability matter.

Key Features

• Heavy load capacity: The mount holds up to 15.5 lbs static and 6.6 lbs dynamic, providing confidence for heavy chartplotters and transducers on rough water.
• Anti-theft lock knob: The lock knob secures the head to the arm so the unit stays in place when you step away from the boat or during transport.
• Military-grade ball joint: Dual-axis 1.5 C-size ball joints with locking knobs allow 360 degree infinite positioning without tools for quick, exact sighting.
• Saltwater resistant construction: CNC-machined 6061-T6 aluminum with MIL-STD-810G powder coating and 1000-hour salt-spray testing resists corrosion and barnacle buildup.
• Reinforced mounting base: The reinforced drill base and included 316 stainless steel hardware are built to withstand engine vibration and prevent gelcoat cracking using the AMPS pattern.

Who It's For

This mount is best for anglers who run mid-size Garmin, Lowrance or Humminbird units and need a durable, theft-resistant mounting option that fits tight cockpits. It suits bass boat anglers, kayak fishermen and small offshore skippers who value a short, rigid arm and corrosion-tested materials.

Those who should look elsewhere include boaters who require very long reach arms or who use models explicitly listed as incompatible in manufacturer notes; the short 3.42' arm is purpose-built for compact installations rather than extended standoff mounting.

Pros & Cons

Pros

• Exceptional static and dynamic load ratings give real-world confidence on choppy days.
• Salt-spray tested aluminum and 316 stainless hardware resist corrosion in saltwater environments.

• Anti-theft lock knob adds security when leaving gear unattended.

Cons

• Short 3.42' arm can be limiting if you need a long reach or elevated mounting position.
