Qualities of a Good Fish Finder for Small Boat


The transducer is the part of the fish finder that emits and receives sonar waves. This part should be a prime factor for consideration when choosing a fish finder.

The transducer will send a signal to the water, which then bounces off the objects in the water. The transducer then picks up the signals and sends them to the main unit to be converted into an image.

Most fish finders have a transom mount transducer. The accessory takes little effort to install and is relatively easy to mount.


There are three different types of frequencies a fish locator may have; single, dual and multiple frequencies. To get a good fish finder, the frequency, which is often linked to a cone angle, plays a very important role. A fish locator with a high frequency means it can send more sonar waves. Consequently, you will have more detail on your screen.

You will especially appreciate the benefit of a high frequency when fishing in shallow water. I recommend going for a single frequency fish finder if you only fish in one water type. However, a multiple frequency fish finder will be ideal if you are the adventurous type.

#Screen Resolution

Most people don’t pay attention to the resolution of their finder’s display screen and yet it important. A higher resolution (more pixels) will lead to clearer readings. The sharpness of the image you get is directly as a result of your resolution.

A minimum screen resolution of 250 x 160 pixels should be good enough. However, this is still substandard if you want really perfect images.


Color technology is a sensation in the fishing electronics world. Devices can relay greater image detail by using millions of multi-colors. The 256 shades of gray that comes with black and white screens has been updated. Therefore, buy a finder that keeps trends.

A color fish finder will show more clearly what’s underneath the water. It will also be easy for you to see in bright sunlight. This is important because you don’t want to catch small fish simply because it’s a sunny day.


Power will determine when and how you will use your fish finder. The power is indicated in watts. A fish finder with high wattage can go deeper in the water and display readings relatively fast. A low wattage fish finder is slower in displaying readings. Such a device can only serve well in shallow water.

As a rule of thumb, the deeper the waters you will be fishing, the higher the wattage your finder should have and vice versa.
