What to Consider When Buying a Kayak Fish Finder

There are several important factors to consider when purchasing a kayak fish finder. Taking the time to understand these key considerations will help ensure you choose the right system for your particular fishing style, kayak configuration and budget.

Transducer Type

A transducer is one of the most important components of a fish finder system. It sends a sonar beam underwater and converts the returned echoes into a visual representation on the display.

Kayak fish finders have several transducer mounting options:

  • Hull Transducer: The transducer is epoxied directly to the kayak’s inner hull below the waterline. This type of fixed mount transducer is in direct contact with the water and provides the best sonar performance. However, the attachment is semi-permanent and difficult to remove and reattach to another kayak.
  • Transom Transducer: The transducer is attached to the transom, which is the flat aft portion of the kayak. Rear mounting is quick and easy with adjustable brackets or scupper hole mounts. However, since the transducers are located outside the main hull, sonar readings can introduce more turbulence and noise.
  • Portable Transducers: Also known as “puck” transducers, this type is housed in a floating housing that can be attached to the side or front of the kayak. Portable converters are extremely versatile as they do not require permanent installation. However, since the pack is further from the boat hull, fewer fish can be spotted directly under the kayak.
  • Paddle Transducer: The transducer is integrated into the paddle blade so it stays in the water while paddling. Very useful, but waves and paddle strokes can affect sonar. Great for drifting and anchoring.

For maximum versatility, portability and ease of use, portable pack transducers are the best choice for kayak fish finders. Anglers using sit kayaks may prefer a transom transducer to keep the transducer in contact with the hull.

Keep your specific kayak design and fishing method in mind when choosing a transducer.

Screen size

A display is a screen where you can view all the sonar information collected by the transducer. Kayak fishfinder displays are typically 3 to 7 inches diagonal. Consider the following when choosing a display size:

  • Visibility: Of course, the larger the screen, the easier it is to view and interpret sonar readings and other fishfinder data. However, even on a compact 3-4 inch display, it’s pretty legible.
  • Mounting: Make sure you have enough flat space to mount the display unit for comfortable viewing when sitting in the seat of your kayak. The smaller the screen, the more flexible the mounting position.
  • Portability: Store the fish finder when not in use and the small screen can be quickly removed to take up less space. A large fishfinder display with a diagonal of 7 to 10 inches can feel large.

For most kayak anglers, a compact 3.5- to 5-inch fishfinder screen offers the perfect balance of visibility, mounting options, and portability. However, if you care about the maximum display size, choose a larger size.

Energy source

Fish finders require power to operate the display and transducer. Kayak models are typically powered in two ways:

  • Battery: Most portable fish finders are powered by an internal rechargeable battery built into the display unit. Run time ranges from 5 hours to 20+ hours, depending on the model. The converter connects wirelessly via Bluetooth or a short cable.
  • Wired: The wired model connects to the kayak’s electric motor’s battery and power system. A long cable connects the transducer to the fish finder. Wired power ensures continuous and unlimited uptime.

Battery-powered fish finders have no cable connection to the kayak, allowing more flexibility in transducer placement. However, you should monitor your battery level and bring a spare battery for day trips.

It’s wired power, so you don’t have to worry about battery life. Choose battery operation when flexibility in transducer placement is a priority. Choose a wired system for hassle-free and unlimited runtime.

Depth Capability

A fishfinder’s maximum search depth range depends on the operating frequency of its transducer. Lower frequencies in the 50-200kHz range allow deeper scanning, while higher frequencies in the 455-800kHz range work more effectively in shallow water.

  • FRESHWATER: The 200kHz transducer scans up to about 250 feet, enough for most lakes and rivers. The Deeper Pro+ casts down to 260 feet.
  • Coastal: Select the 400+ kHz radio frequency that can scan reefs and structures at depths of approximately 100 feet.
  • Offshore: Serious open water anglers need low frequencies from 500 feet to over 1,000 feet, which is useful when trolling offshore. The Garmin Striker 4 has a maximum altitude of 1,600 feet.

A dual frequency transducer combines both low and high frequencies in one housing, offering the best of both worlds for varying depths. Overall, aim for depth skills that are appropriate for the fishing spot. If you want to kayak just 60 feet deep on shore, you don’t have to pay for 1,000 feet of sonar range.

Extras and special features

High-end fish finders come with many advanced features and connectivity beyond just sonar. Evaluate the following additional features to see if they’re worth it for your needs.

  • GPS: Built-in GPS lets you track kayak speed, mark waypoints at fishing hotspots, follow navigation routes, and even create custom depth contour maps can.
  • Wireless: Bluetooth and WiFi allow you to wirelessly connect the transducer and sync your fishfinder sonar data with your smartphone app. Great for sharing waypoints and fishing photos.
  • Nautical Charts: Preloaded inland sea charts or offshore coastal charts make navigation easier and show underwater contour lines.
  • Maps: Some models record sonar history and use it to draw live depth maps showing seafloor structure and coverage. Garmin’s QuickDraw is an example.
  • Satellite Imagery: A high-quality navigational fish finder overlays satellite imagery onto a nautical chart for improved visibility on the water.

Prioritize additional items that greatly enhance your kayak fishing experience. In most cases, GPS and wireless smartphone connectivity provide the greatest benefit. Focus on core sonar and depth sensing performance before paying for fancy premium features.

Frequently asked Question

Here we address some of the most common questions kayak anglers have when investing in a fish finder for the first time.

Do fish finders actually work well for kayaks?

Yes, fish finders definitely improve kayak fishing. Portable transducers can be placed on the side or front without permanent installation.
Smaller 3- to 5-inch screens are suitable for deck mounting. Make sure the transducer is submerged in water and not exposed to excessive turbulence.

What fish finder features are most important for kayaks?

Look out for high-quality transducers, a bright, sunlight-readable display, a robust 200-400ft sonar depth for most freshwater sites, and a minimum 5-hour battery life. Additional features such as GPS, wireless connectivity and downscan imaging are nice upgrades if the budget is manageable.

What’s the best way to power a fish finder on a kayak?

For a battery-powered viewfinder, a small 12V, 7-10 amp-hour sealed lead-acid battery works well, providing over 10 hours of runtime. The price is about $25. Electric kayaks can be wired to the mains power system for unlimited, maintenance-free power.

Where is the optimal mounting position for the fish finder display?

Most anglers mount the display near their sitting position for easy viewing while paddling or casting. The adjustable swivel mount can be used to tilt the screen backwards to reduce sun glare. Suction cup mounts allow for repositioning.

Can fish finders work effectively in very cold water?

The colder the water, the more sonar energy it absorbs, reducing performance. But the latest CHIRP fish finders work well in almost freezing water. Cold weather may reduce battery life. Very cold water can limit depth range.
