What is a fish finder?

A fish finder is an instrument that detects reflected pulses of sound energy. So that it is used to locate fish which lives in underwater. In the USA, people call it sonar. The Marine Raider, the compass and the GPS navigation systems these three integrate and makes a high degree fishfinder system.

Fish Finder Basics

Sonar is required to operate all types of the fishfinder. It produces a sound wave and sent it through the water and after reflecting from fish it returns back to the receiver. There are some basics of using a fish finder and to operate it properly.


Beam means a cone that forms by spreading the sound wave. When something within this beam is encountered by sound wave, it returns to the fish finder. This small amount of time is calculated for finding fishes through the fish finder.

Cone Angles

Angular measurement of the sonar beam is called the cone angle. It is represented in degrees. Fish finder model and manufacturer are a variable for cone angle.

Fish Targets

The unprocessed sonar return that is called an “arch”, or as a Fish ID symbol helps to display the fish targets.

Water Clarity

The integrity of the signal is greatly affected by the water’s clarity. Strong winds or currents can create bubbles in the water and it will create disperse the signal.

Thermo clines

Thermo clines are called the “fronts”.It means where warmer waters intersect with cooler waters. It has a great impact because fish normally prefer a certain temperature to live and it will help to figure out the exact position of fish.


The electrical signal is taken from a transmitter via a transducer. It then turns it into sonar. It will then send it out. All returning echoes are captured from it and then it converts them into electrical signals.

Transom Mount

The transom-mount transducer is the easiest to install. A plastic transducer is appropriate for aluminum or steel-hulled boats because it helps to avoid potential electrolysis problems.

Trolling Motor Mount

Trolling Motor Mount has two slots for a hose clamp.PD-W transducer is designed for mounting on trolling motor.

The LCD Display Screen

The LCD displays the sonar information and the displays are measured in “pixels”. Pixels are the little square blocks on the screen and It will make up the image.
