A fishfinder, also known as a sounder, can be defined as an instrument that uses sound navigation and ranging (Sonar) techniques to locate fish underwater by detecting the reflected pulses of sound energy. Modern fishfinder devices have a customized display that enables the operator to interpret the information from the reflected sound and is, therefore, able to identify a school of fish, underwater debris and even the depth of the water at any given location in the water body. Fishfinder instruments are used by both the commercial and also the sports fishermen. They make the fishing activity easy and very interesting if not fun.

How Do We Read a Garmin Fishfinder?
As you read this section, you will be acquainted with most, if not all, of the parameters that can be displayed on a Garmin sonar fishfinder.
For the Garmin echo series, the water column is displayed on the right edge of the screen. You can know how deep the water is at any location you are by reading this column. The boat is basically located at the surface where the reading is zero, and the bottom of the water body is at the level where the rock and the debris in the water appear as a solid line. The right section of the screen shows what is right under the boat at any particular moment while the left portion shows what was under the boat a few minutes past.
For the image displayed on the screen, strongest returns show their color in yellow and weaker returns will show up on the screen as blue and red. Rocks and other strong structures will show up in yellow. Fish can be located anywhere in the water and would give strong returns. On the screen, the fish will show up as arches. This makes it easy to identify fish and school of fish.
The fish finder has a number of buttons that can help you customize your fish finder and read even finer details of the parameters being shown. The power button has a dual purpose of switching on the device and also setting the back-light brightness level. These brightness levels are pre-set into high, medium and low levels. You can use the power button to toggle between these levels.
All the functions of the echo series can be accessed using this menu button. By pressing the button, you get to the various choices of the parameters to alter. The first is the page option. Highlighting this and pressing the enter button, you can choose how your display will be. The choices in this category are full screen, split zoom screen with a depth reader on one side and a zoom on the other, a flasher, log, and numbers for basic depth values and split frequency showing both the 77 kHz and 200 kHz returns.
You can use the range option to change the depth scale to the value that you wish. The gain option helps you adjust the sensitivity of the transducer.
