What is a fish finder

Fish finders are instruments or devices that help us to trace the location of fish in their habitat. The mechanism used by the fish finders is that they form of sound energy from the water.

Here are some of the uses of fish finders

  • They help us to locate bait as it is difficult to find one on the surface.
  • With the help of fish finders, we can locate the flat areas or structured areas which make fishing exercise easy. Fishfinders will help us to find the specific location of certain species with ease.
  • Fish finders are not only for finding fish and their bait. When we go for rides in our Kayaks, we may want to take a dive. Fish finders help us to know the depth of water at any position so that we do not end up getting hurt.

How fish finders work

Like every device, using fish finders requires practice so that we can get the mechanism in our fingertips. However, what do find finders work?

In details, fish finders are fitted transducers which have sensors underwater that transport information back to the display. The display is a simple screen with a powerful mechanism that converts the raw data into a more readable form.

Transducers transmit sonar waves into the water. When the waves hit a hard object, they bounce back to the screen having estimated the size and depth of the object.

Now that we know how fish finders work. How do I read a fish finder?

How do I know I have the best fish finder?

When we shop for fish finders, what are the desired features that we want our fish finders to have? This read helps us to get the most desired attributes of the best fish finder. What should I look for in a fish finder?


Transducers are the most important components of fish finders. They are the devices that transmit sonar waves or sound waves to the water. They help us to identify the objects as the waves make an impact with a solid object. The same transducers convert the bounced waves into a more readable form, which is in a picture form.

With the help of frequencies, we can get a clear visual of water is beneath the surface of the water.  High frequencies enhance the visual aid because they transmit more sonar waves. For instance, fishing shallow waters require very high frequencies of about 400 or more Kilohertz (KHz).

However, many transducers come with frequencies which are lower than most of us require, especially when fishing in shallow depths. Higher depths of water can work well with lower frequencies of around 50 KiloHertz (KHz).

Screen Resolution

I always have a screen display that allows me to view the pictures clearly. The pixel level determines how much and how clear the screen will let us take a view. Let us get how pixels determine the amount and clarity of the pictures transmitted.

Screen resolution

If the screen has 600*600 pixels, it means we have 600 dots in each row running from left to right and 600 dots in each column running from top to bottom. Higher pixels shows more details but are in turn more expensive. Looking at the brighter side, we see better with more money.


We don’t want to run around with black and white screens that get us wondering the fish we may have below the water surface. We need  screens that show color and even the beauty of the vegetation below.

Color screens on the plus allow vision when there is a bright light, unlike the black and white screens. With a pitch black night or cloudy weather, we all agree that it is a sight to behold with all the beautiful popping multi-color. Just get a color screen as it makes fishing another exciting experience.

Cone Angles and Beams

What is a cone angle in fish finders? Cone angles are the measure of the beam that is sent from the boat to the water and looks like an inverted cone ice cream.  As the beam goes deeper into the water, it becomes wider.

A wider cone angle provides a bigger viewing area. In the market, the transducer cone angles range from as small as 9° (degrees) to as large as 90° (degrees). Most people prefer the 20° cone angle as it works great in different water depths.

Transducers enhanced with a larger number of beams enable us to cover more water. If we can cover more area at one point, it makes fishing easier and faster. Get a fish finder with a higher degree of cone angle as well as one with more beams, like a triple beam or more.

Transducer Material

One thing we should know about transducers materials is that they defer depending on the type of boat we use. For sports fishing or cause fishing, the plastic material on the transducers works well. The good thing about the plastic material is that it works on most boats.

When I use transducers within-hull or thru-hull made of fiberglass or metals, I use the plastic housing. We can sue the steel housing for hulls made of steel or Aluminum. Bronze housing is recommended for hulls made of fiberglass or wood.


The amount of power in a fish finder is the most important feature to look for in the device. The greater Wattage (W) a fish finder produces, the faster the display and the deeper the readings. Less wattage is suitable for shallow depths because readings are slower.

Power determines the speed of sonar waves from the boat and back, and so it determines the kind of readings that will be displayed. More power translates to a faster speed of sonar waves and in return provides a clear reading.


We want fish finders which we can move with, where we go fishing. Portable fish finders come I handy especially when we rent boats or fishing from the shore. Buying a fish finders can be more costly than buying a fish finder with a portable feature. However, in the long run, they turn out to be more economical and convenient.

Getting a fish finder with a GPS is very important, especially for beginners. It helps us get home in case of an emergency. The GPS also helps us trace our maps in waters that we frequent.

We are choosy when it comes to products manufactured by specific companies. Maybe it is because of the great or poor reviews from other customers.

Maybe it is because of the great or poor reviews from other customers.

But we believe in getting the best of the available fish finders from the best manufacturers.

Miscellaneous features

There are varieties of features that we may overlook while shopping for fish finders. Some characteristics such as the type of sonar waves are also important. Check sonar waves that are suited the boat and the readings that are appropriate.

Common mistakes when shopping

Three mishaps occur when we shop for fish finders. What are mistakes to avoid in buying fish finders? Here are three of the most common mistakes we make when shopping:

  • Purchasing a portable fish finder because of the cost.
  • Overlooking the features of Sonar that suit our specific needs.
  • Buying a fish finder which is not fitted with a GPS.
