Buyers Guide

It is crucial to read the buyer’s guide for any equipment or product you are considering purchasing as it includes information that will help you decide which equipment is best for your needs. This is because it helps you understand the real factors that influence the product, and how your desired use for the product fits into each feature. Here are some factors you should take into consideration before buying or using a fish finder.


No matter how much data a fish finder collects, if it can’t display the data to the user clearly, it is useless. Therefore, it is important to pick a fish finder with high quality display. Generally, this means looking for a fish finder that has a high resolution and produces color images. In addition to resolution, it is advisable to choose a fish finder with large screen display, making it easier for you to see images clearly while fishing and fish finding.


The transducer, which generates sonar waves, is the most important part of the fish finder, as it collects the data, that is then used to create the images. Sonar waves bounce off underwater objects as they are sent down by the transducer, which are then picked up and recorded to determine the distance, location, and size of the object that the waves interacted with. The information is then displayed as images on the screen. You will not be able to see what lies beneath the surface if the transducer is not of high quality.


In general, dual frequency transducers come in 60-degree and 20-degree cone sizes. A major factor in transducer performance is frequency. The most commonly used frequencies for transducers are 200, 192, 83 and 50 kHz. They are related directly to cone angles. You should choose high frequencies, like 192 and 200 kHz, when fishing in shallow water. It is important to remember that high-frequency transducers deliver more detail than low-frequency ones.


Easy navigating is not possible without a servicable navigation system. Your GPS will assist you in returning safely, while also saving you time. Thus, GPS-enabled devices are the best option, not only to navigate stress-free, but also to add waypoints so you will know precisely where you are, and where you need to go next.


Your fish finder displays readings faster if it has more watts and power. By increasing the wattage, the accuracy of the device can be maintained at a greater depth. Power is not as important when it comes to shallow freshwater. However, you should always make sure your device has the maximum amount of power possible if you intend to go deeper.


Q: What am I looking at with Side Imaging?

A: Using side imaging, you can view the world from 180 degrees on either side. High-frequency beams scan up to 240-foot radius to the left and right of your boat. A great view of the ocean bottom is created by combining each slice’s return image with those taken immediately before and after it.

Q: What does CHIRP mean?

A: Compressed High-Intensity Radar Pulse is the acronym for CHIRP. It is an imaging system that works by cycling through multiple frequencies to produce a high-quality image.

Q. How do I properly maintain my transducer for optimal performance?

A: An anti-fouling paint based on water can be applied to transducers to prevent from corrosion and have an optimal performance. Please do not paint your transducer’s paddle wheel if it has one, as this determines the speed.

Q: How do fish finders work?

A: Sound waves (sonar) are generated in the water by fish finders to capture the reflections. This information then determines the object underneath as rock or fish etc, as well as their location, and size.

Q: Can fish finders work on ice?

A: Sonar technology allows fish finders to pinpoint fish directly on top of the ice. You should ensure that the ice surface is smooth and clear, and keep the transducer from coming into contact with air.
