An Introduction

One of the great mysteries of boating ... Imagine what lies beneath us, between the water surface and the bottom. How deep water, where submerged rocks. Where's the fish?

A fish finder is an electronic device with a screen and a transducer that uses sound waves ( "Sound Navigation And Ranging" the sonar acronym") to "see" in your boat.

The unity of the sonar emits high frequency sound waves into the water and they expect him back after rebounding on objects underwater. By treating the outgoing and incoming waves, a fish finder can determine, among others, the depth of the water, and you see the submerged structures and small corners where malignant fish are hiding.

Screen

The display of a fish finder shows you what the sonar sees under your boat. The screen can be monochromatic (different shades of gray) or in color, depending on your particular device.

Transducers

These waves leave the transducer forming a cone called a "bundle". Beam width describes the angle of the sound waves which pass through the water.

A wide beam transducer shows a larger area of ​​the bottom in shallow water. A thin beam works very well in deeper water.

One of the keys of the good performance of a transducer is mounted in a place where there is no turbulence or bubbling water - one side of the cross, for example. The transducer should be installed perpendicular to the bottom of the lake to enjoy the full performance of waves.

The little extras

Temperature sensors tell you the temperature of surface water - which might not be relevant with respect to the temperature of deeper water.

A finned transducer can give you fairly accurately the speed of your boat. This is especially important if you practice trolling. In addition, the finned transducer can tell you the distance that crossed the boat during a certain period.

Bottom hardness is displayed as a horizontal line on the screen. With a little experience, you will come to see if the background is solid or muddy.

Fish icons potentially indicate the target fish, as small fish shapes on the screen. In other apparatus, the detected fish are shown as fish arches - a much clearer way to see the difference between grassland that look like fish and real fish.

The alarms sound when you are in shallow water, to prevent you failed ( You Touch The Background ). This can happen easily when you wear all your concentration to catch fish! Remember that as the transducer is located in the stern, the bow is already in shallow water at the time the alarm sounds. Stay tuned.

A Simple warning

Remember that even if the fish finder can show you where the fish is hiding, it's still up to you to catch it!

Some screens work well under direct sunlight while others fade or fade in the sun. This is important: If you can’t read the screen easily by sunny day, as well use your device as a paperweight!

The resolution of the screen, measured in pixels, determines the sharpness of the image you see. More pixels result in a clearer representation of what happens in the water under the boat.
