How To Choose The Best FishFinder for a kayak?

There are several factors to choose a fishfinder for a kayak. There are several types of fishfinder available in the market. From low cost to high cost, all fishfinder has one thing in common, to find you the perfect spot for fishing. To choose a fishfinder for kayak, you need to consider some factors and decide accordingly. We have pointed out some of the crucial factors to check before getting a kayak fish finder.



It is vital to see the sonar readings properly on your fishfinder. My suggestion is to get a fishfinder with a decent screen size. A good display will offer better resolution, and the hi-resolution screen will allow you to see the data more clearly. A big screen size will help you to see different sonar data at the same time. Some fishfinders show multiple sonar data at the same time.



For better performance it is suggested to get a fishfinder with more power. Higher wattage allows the fish finder to display the readings quickly.


Sonar System

Fishfinder uses sonar to show you the data on the screen. As the technology is evolving, advanced fish finders are coming with different types of sonar systems. There are CHIRP sonar, DownImagin/DownVision/DownVu, StructureScan, SideImaging/SideVu and more. These are to make sure you get the data more accurately. An advanced sonar system’s fishfinder is likely to cost you more than typical fishfinder.



A transducer is an element which transmits the sonar waves to the water. Most of the time, fish finders will come with transom mount transducers. These are quite easy to install and use. Some advanced fish finders with advanced sonar technologies might require you to get additional and different transducer to work.



If you are planning to fish on a lake, river or the saltwater, you may want to take benefits of having GPS integrated on the fish finder. Advanced fishfinders allow you to get more navigational features along with the GPS function. Follow the chart above to see which kayak fishfinder has GPS.



Since we are looking for kayak fishfinders, it is better to choose a compact fishfinder to mount on the kayak easily. If you have a big kayak, then you can go for big fishfinders. However, if space is a major concern for you, you can check the compact design or portable fish finders.



Do you need a portable fish finder or a regular fish finder? Many kayak anglers are using portable units to save money and time. Most of the portable units are easy to manage. Nowadays, there are sonar phones which use your phone’s display to show readings and data.


Depth Reading

Checking the depth reading limit of a fishfinder is important. While kayaking, you are supposed to go to different places for fishes. It’s important to know the depth beneath your kayak.


Fishing on kayak requires you to get wet at a time to time. While choosing a fish finder for kayak, it is important to check if it is waterproof or can handle the outdoor environment.
