How to Choose an Ice Fishing Fish Finder

Type of frequency

There are single, dual and multiple frequency ice fishing fish finders to choose from. And while each has its own set of pros and cons, your choice comes down to what best suits your needs. If fishing in shallow waters, something a higher frequency will benefit you. As the frequency increases, sonar images become clearer and more detailed images. Lower frequencies work best when fishing in deeper waters.

Colored screen

There is no denying that a colored screen makes it easier to see images. It allows underwater objects and fish to stand out from the stones and debris. Additionally, reading in the dark or poorly lit conditions is easier with colored screens. Consider going for backlight LED, as it boosts the performance of a colored screen. Black and white screen variations are also available at a lower price.

Power source

When it comes to the power source of a fish finder, there are three things to think about – charging time, wattage and longevity of batteries. The best ice fishing fish finders have higher wattage. This translates to a faster relay of sonar data from underwater.

Transducer material

Transducers are made from a variety of materials, and not all of them are suitable for every boat. Most manufacturers opt for plastic because it is weatherproof and doesn’t retain water. Plastic is also a perfect choice for casual fishing. However, if you plan on doing intense fishing, you should consider sturdier materials like stainless steel, wood, fiberglass, and bronze.


Ice fishing gets more exciting and enjoyable when you have the right equipment. When it comes to fish finders, there are many options to choose from. The finders reviewed in this post offer the best results, and come at different prices. For instance, the Deeper Smart Pro is an excellent choice for low budget needs.
