The Angler’s Anchor: Your Guide to Choosing the Right Fish Finder Mount

A fish finder is a great tool for catching more fish. But that tool needs a strong home on your boat or kayak. A good mount keeps your screen safe, steady, and perfectly angled for viewing. This guide helps you pick the best mount for your adventures.

Key Features to Look For

When shopping, focus on these important parts:

Adjustability: You need to aim your screen exactly where you need it. Look for mounts offering 360-degree rotation or multiple tilt points. This lets you see the screen in bright sun or from different seating spots.
Compatibility: Make sure the mount fits your specific fish finder brand and model (like Garmin, Humminbird, or Lowrance). Also, check if it matches your boat type.
Stability and Vibration Control: A wobbly screen makes it hard to read sonar readings. High-quality mounts use strong joints and materials to keep the screen still, even when the water gets choppy.
Quick-Release Function: This feature lets you easily remove the screen for storage or security when you leave the boat.

Important Materials That Matter

The material determines how long your mount lasts and how much weight it can handle.

Plastic vs. Metal

High-Grade Plastics (Nylon/ABS): These are light and resist rust and corrosion well, making them great for saltwater use. However, cheap plastic can become brittle in strong sunlight over time.
Aluminum: This is the strongest choice for heavy units or rough water. Aluminum offers excellent rigidity. Ensure any aluminum is powder-coated or anodized to stop rust.

Factors That Improve or Reduce Mount Quality

Not all mounts are built equally. Pay attention to these details:

Quality Boosters:

Thick Wall Construction: Thicker tubes and bases resist bending and flexing.
Stainless Steel Hardware: Screws and bolts made of stainless steel will not rust out, which is crucial for marine environments.
Locking Mechanisms: Strong knobs or levers that firmly lock the arm position prevent slippage during rough rides.

Quality Reducers:

Flimsy Knobs: Small, weak plastic knobs strip easily or fail to hold heavy screens steady.
Poor Finish: If the metal looks rough or the plastic has thin spots, the mount will likely fail sooner.
Limited Weight Rating: Always check the maximum weight the mount supports. Overloading a mount guarantees instability.

User Experience and Use Cases

Think about where and how you fish when making your choice.

Kayakers vs. Bass Boats

Kayaks: Kayakers need low-profile mounts that attach securely to small surfaces, often using track systems (like Scotty or Railblaza). Portability is key here.
Bass Boats/Trawlers: These boats usually use heavy-duty pedestal mounts drilled directly into the deck for maximum stability, often accommodating larger screens.

A good user experience means simple installation and frustration-free adjustments on the water. If you spend five minutes fighting the knobs every time you want to check your depth, the mount is hurting your fishing time.

10 Frequently Asked Questions (FAQ) About Fish Finder Mounts

Q: What is the difference between a suction cup mount and a bolt-down mount?

A: Suction cup mounts stick temporarily to smooth surfaces, making them easy to move. Bolt-down mounts screw permanently into your boat or kayak deck, providing the strongest, most vibration-free hold.

Q: Can I use a mount designed for a small unit on a large fish finder?

A: No. Always check the weight limit. Using a mount that is too small can cause your expensive screen to fall off, especially in rough water.

Q: Do I need a special mount for saltwater?

A: Yes. Saltwater demands corrosion resistance. Look specifically for mounts made of high-quality aluminum or marine-grade plastics that use stainless steel hardware.

Q: How high should my fish finder screen be mounted?

A: The screen should be high enough that you can easily see it without looking too far down, but low enough that it doesn’t block your view of the water or the bow of the boat.

Q: What is a “ram mount”?

A: RAM Mounts are a very popular brand known for their ball-and-socket system. They allow for extreme adjustability using a single tightening knob that locks all joints simultaneously.

Q: Is installation difficult?

A: Suction cup mounts require almost no skill to install. Bolt-down mounts require basic drilling and screwdriver skills. Always follow the manufacturer’s instructions closely.

Q: How do I stop my screen from vibrating?

A: Vibration usually comes from weak joints or low-quality materials. Ensure all knobs are tightened fully, and consider upgrading to a metal pedestal mount if you fish in rough conditions.

Q: Do these mounts work with transducer cables?

A: The mount holds the display screen. You still need to route the transducer cable neatly along the boat hull to the back, but some mounts offer clips or channels to help manage the slack.

Q: Should I remove my mount when trailering my boat?

A: For small, light units, it might not be necessary. However, for large screens or if you travel long distances on rough roads, removing the screen or the entire mount protects it from road vibrations and theft.

Q: What is the purpose of a flush-mount kit?

A: A flush-mount kit allows you to sink the display unit directly into the dashboard or console, giving a very clean, professional, and low-profile look.
