Top 5 – Good Inexpensive Fish Finders For Kayaks

Kayak fishing is a popular sport among many anglers. However, if you are kayak fishing, don’t you want to catch the greatest and biggest fish in the water? Don’t you want to find a great fishing spot? If this is the case, you should definitely own a fish finder for kayak fishing. You will find lots of fish finders for kayaks available in the market. However, finding good inexpensive fish finders for kayaks is difficult.

You may be on budget and looking for cheap fish finders for kayaks. Have no fear, we have gathered a bunch of best inexpensive fish finders that you can purchase for your kayak. However, the word ‘inexpensive’ differs from person to person. Some perceive 150 dollars to be inexpensive, others see 50 dollars to be inexpensive. That’s why we have covered all of the price range and provided you with good inexpensive fish finders for kayaks that will suit your budget.


Things you should consider:

Display: Having an 8-inch or 10-inch display fish finders for kayak fishing is not a wise choice. As you know that kayak is very slim and small and many kayaks are only for one person. Personally, I think display size less than 5-inch is perfect. However, a display size of 5-6 inches will be a hassle to mount but it is not impossible. Another thing to consider is the resolution of the screen. The higher the resolution the clearer picture you will get. Having a resolution less than 240 x 160 pixels is also not a great choice.


Transducer: The main component of a fish finder is the transducer. The transducer is a device that transforms the sound wave to the fish finders display in the form of pictures to locate the structure of the underwater. Frequency is the main thing you should consider. The higher the better details you will get.


Power: If you buy a fish finder that needs external power source then you may have to DIY the power source. But if you want to avoid this hassle, then you should get a portable fish finder that runs on its own batteries. However, we have chosen good inexpensive fish finders for kayaks that won’t be a hassle.

Other Important Features:

All the models of HawkEye FishTrax come with intelligent sonar from FishTrax. It has got three frequency modes to choose from:

200 kHz: As I said earlier the higher the frequency the better the underwater view. 200 kHz means that the transducer will produce 200,000 sonar pulses every second. It shows great clear details of the structure and the fish. The best use for this frequency mode is when you are fishing in a shallow water where the details are most important. Also, check our article on ‘Best Fishfinder For Shallow Water Fishing‘.


83 kHz: 83 kHz means that the transducer will produce 83,000 sonar pulses every second. Although the 83 kHz shows fewer details and definition, however, it has a great depth penetration ability. It is useful when you are fishing in a deeper water and where the water is so deep that the 200 kHz can’t reach.


Dual-View: These portable fish finders for kayaks also have the dual frequency mode. In this mode, it uses both the 200 kHz and the 83 kHz. The 200 kHz will show a more detailed structure and fish, and the 83 kHz will show details of deeper water where the 200 kHz is unreachable.


The great thing is that lots of cool accessories are available for this device from carrying bag to fish finder and transducer mount. To check these accessories, click here.
