Best Kayak Fish Finder
Garmin Striker 4 with Portable Kit Garmin Striker 4 with Portable Kit

Garmin Striker 4 is a very powerful yet affordable fish finder that uses a 4 pin connector and has 2 cone-shaped beams. While searching great depths, you can adjust the beams.

This fish finder will help you scan the depth of 228 meters or 750 feet in saltwater. While in freshwater, it can scan 487 meters and 1600 feet. 

However, this is only possible if you use a transducer of 50 kHz.

A CHIRP sonar allows the Garmin Striker 4 to build quality images. Better images will enable one to get a clearer picture of the targets and locate them accurately. CHIRP also separates the targets incredibly that further aids in precision.

The 2D sonar in this device offers Fish Symbol ID, which differentiates the fish using icons and also mentions the depth each target fish is at. Flasher Mode allows one to get information on the nearby targets like depth and the strength of the sonar return. 

This is particularly useful while fishing from a single position or ice fishing. Auto Gain function filters any unwanted noise. 

A-scope is another function much similar to Flasher Mode. It just provides information from the most recent sonars in a vertical layout. The device also has an Ultra-scroll feature, which enables one to scan at a faster speed. However, it compromises the image quality to a certain degree.

All of the above makes it the ideal choice for our top-best fish finders for kayaks.

What we like:

  • Offers Fish Symbol ID for locating fish in different depths.
  • Produced from high-quality materials
  • 3.5, 5, and 7-inch display

Why Do You Need Kayak Fish Finders?

While on a fishing expedition, it is important for one to be fully equipped. Sure you can go without the aid of technology and leave it all to luck or chance, or embrace the change and use technology to your advantage – we are sure you’ll catch more fish!

For catching the biggest and best fish, it is important to have a fish finder to locate the nearest and largest fish and go fish with more precision. But one also needs to know this, that Kayaks and boats have different fish finders. What might work well on a boat might not work on a Kayak.

Buying Guide for Kayak Fish Finders

For buying the best fish finders for kayaks, you need to consider several aspects of the gadget. We have listed some common questions that might help you find the right gadget for yourself.


For people traveling far into the sea for fish, choosing a single unit fish-finder with a built-in GPS will probably best. It will ensure that one does not get lost in the sea. As the space in Kayak is scarce, this will serve as a GPS as well. This might cost a little extra, but for long trips, especially in the sea, we think it’s worth it.


You can connect the transducer to the Kayak in multiple ways:

  1. Some can be attached to the bottom of the transom.
  2. Some of them can be stuck to the trolling motor.
  3. Modern Kayaks have scupper holes to drain water. They allow the transducer to pass through. However, if you own an old kayak, make sure you get the right depth finder.

Depth of the Fishing

For people who are more used to fishing in ponds and streams where the water isn’t as deep, a side imaging unit is a good option. This will help in exploring all the available fish on the surface. However, if someone goes deep into the water, then a down imaging sonar is better as this will help portray a clearer image of fish deep underwater.

Power Source

Most of the fish finders require a large battery. But, on a kayak, it can be a problem where space is limited. Make sure that you get a portable battery fish finder that can also transmit data to your phone, so it doesn’t hinder your fishing. On larger kayaks, a waterproof battery bank is a great option. 

The Room

Next, an angler must have an idea about the space in the kayak. You must know if there is enough space for a fish finder of that size? If space is limited, you can always opt for a portable. mobile one. 

These are small, easy to carry, and lightweight. You just have to download an application, and the fish finder will connect to your smartphone. You can simply toss the sensor in the water using the fishing line, and you start seeing everything.


Other, more important facts to consider are your fishing style and your kayak type. If you don’t have a kayak yet check out our favorite fishing kayaks for under $1000.
