How to Choose the Best Fish Finder? Consider these Features:

Selecting a fish finder is not so easy. Here are some key features to keep in mind when buying the best fish finder.


Display is very important thing for a fish finder. You need to consider some display features like colorful or not, display size, resolution. A colorful display can give a better result than a black/white display because it gives detailed and clearer pictures of fish spots. You can easily identify fishes on the display while it’s difficult on black/white display. Next comes display size and resolution. The bigger display is more effective to identify the exact position where the fish are. Higher resolution will give sharper and realistic image. So, a minimum of 240x160 pixel resolution is recommended for a good picture.


When you’re buying a fish finder, you’d know about frequency. If you go to shallow water, then higher frequency like 192 or 200 KHz is best for you. Otherwise, Lower frequency like 50 KHz is best for salt water. Higher frequency gives more details about the fish spots and lower frequency gives wider range. Now most of the devices come with dual frequency (Higher and Lower). So, you can switch frequency anytime based on your need.


Power is one of the main factors of a fish finder. A good fish finder needs higher wattage as power is measured in wattage. If the power is higher, the device will work faster and give accurate result. Low powered fish finder is less effective showing the results. But, lower wattage can do the job in shallow water. So, 600 watts is good for shallow water otherwise 1000 watts’ device is recommended.


A GPS option in the fish finder helps to find your previously found fishing spots. It minimizes your searching efforts. Most of the fish finders in the market come with a GPS System.


Price is an important factor while buying a fish finder. You’d invest your sweet money on the product that meets all your needs. Remember that, the more features it has, the more it will cost. But, don’t miss the features discussed above when you buy your fish finder.


So, what’s on your mind? We hope, we made your job easier to choose the best fish finder for you. You must be selected which one to buy. Please write to us if you have any queries. Happy Fishing.
