Your Essential Guide to Choosing the Best Fish Finder Mount

Finding the right fish finder mount is just as important as picking a great fish finder. A good mount keeps your screen steady, easy to see, and safe from water damage. This guide will help you choose the perfect match for your boat or kayak.

Key Features to Look For

When shopping for a mount, look closely at these important parts:

Adjustability: You need to easily tilt and swivel your fish finder. This lets you see the screen clearly, even when the sun is bright or you are moving fast. Look for mounts with strong ball joints or multiple pivot points.
Stability: The mount must hold your screen steady. Bumpy water should not make your screen shake wildly. A solid base and strong locking mechanisms are crucial.
Compatibility: Check if the mount fits your specific fish finder brand and model (like Garmin, Lowrance, or Humminbird). Also, make sure it fits the surface where you plan to install it.
Quick Release: A quick-release feature lets you take your fish finder off the boat fast. This is great for security or when you need to move the unit to another boat.

Important Materials for Durability

The material of the mount decides how long it lasts, especially when dealing with saltwater and sun.

Stainless Steel vs. Aluminum vs. Marine-Grade Plastic

Stainless Steel: This material is very strong. It resists rust well, making it a top choice for saltwater boats. However, it can be heavier and sometimes more expensive.
Aluminum: Aluminum is lightweight and strong. It resists corrosion better than regular steel, but lower-quality aluminum might still corrode over time if not properly coated.
Marine-Grade Plastic (Nylon/ABS): High-quality plastic mounts are affordable and naturally resist rust. They work perfectly for lighter units or kayaks. Ensure the plastic feels thick and not flimsy.

Factors That Improve or Reduce Mount Quality

Not all mounts perform the same way. Some small details make a big difference in quality.

What Makes a Mount Better?

Strong Locking Knobs: Big, easy-to-grip knobs that lock down tightly ensure your settings stay put.
Thick Base Plate: A wider base spreads the weight better and prevents wobbling.
Corrosion Resistance: Look for powder-coated finishes on metal parts or stainless steel hardware. This prevents rust from weakening the mount.

What Makes a Mount Worse?

Flimsy Hardware: Small, weak screws or plastic hinges break easily.
Limited Angles: If the mount only moves up and down, you might struggle to avoid glare.
Cheap Coatings: A thin coat of paint on metal parts wears off quickly in the water, leading to rust spots.

User Experience and Use Cases

Think about how and where you fish. This guides your mounting decision.

Kayak Fishing

Kayakers need mounts that use suction cups or scupper-hole mounts. These do not require drilling into the kayak hull. Suction mounts are easy to move, but they sometimes lose grip in very rough conditions. A strong, low-profile mount is usually best here.

Bass Boats and Deep-V Hulls

These boats usually have more space. Many anglers prefer flush-mount or deck-mount options. These offer the most permanent and stable hold. You secure these directly to a flat surface using bolts. This setup handles high speeds and rough wakes without fail.

Trolling Motor Mounting

If you use a trolling motor, you might want a specific mount that attaches your screen near the motor controls. This keeps your hands free for steering and adjusting the motor while watching the sonar.

10 Frequently Asked Questions (FAQ) About Fish Finder Mounts

Q: How important is the mounting material?

A: The material is very important. Marine-grade plastics or stainless steel last much longer when constantly wet or exposed to sun.

Q: Can I use a suction cup mount in saltwater?

A: Yes, many suction cup mounts work in saltwater. Just clean the surface well before attaching them to make sure they stick firmly.

Q: What is the difference between a flush mount and a surface mount?

A: A flush mount sits level with the surface, often requiring you to cut a hole. A surface mount screws directly onto the top of the dash or deck.

Q: Do I need a special mount for a kayak?

A: Kayaks often use specialized mounts like suction cups or scupper mounts because drilling holes can damage the hull.

Q: How tight should I make the adjustment knobs?

A: Tighten the knobs enough so the screen does not move when you bump it, but not so tight that you cannot adjust it by hand later.

Q: Will a cheap mount cause my screen to shake?

A: Yes, cheap mounts often use weak plastic or poor joints. This lets the screen vibrate a lot, making it hard to read while moving.

Q: What is a RAM Mount?

A: RAM Mounts are a popular, high-quality brand known for using strong ball-and-socket systems that offer extreme adjustability and hold power.

Q: Do I need to remove my fish finder in winter?

A: If you store your boat outside in freezing weather, it is smart to remove the unit itself. The mount can usually stay attached.

Q: How do I prevent my mount from rusting?

A: If you use metal mounts, regularly rinse them with fresh water after using them in saltwater. Check that all screws are stainless steel.

Q: Can I mount my fish finder on a windshield?

A: Some mounts work on flat, smooth windshield sections, but suction cups work better on flat fiberglass or metal surfaces than on angled glass.
