Before you can decide which fishfinder is the best one for you, you ought to know the way the fishfinder performs

Fishfinders utilize sonar technology to find fish-or any other good object-under the surface of the water. Sonar sound waves move through the water. The farther the sound waves travel, the more they fan out into a cone shape and increase in diameter. Deeper water obviously causes the cone to become bigger as it moves from it's origin. Whenever that the sonar wave strikes against a good object of any material, it will bounce an echo back to the transducer. The form of the item struck will be decided by how long it took the signal to head out and then bounce the audio wave echo back in contrast to the surrounding area. The echo will then show up on your fishfinder screen and you'll observe the aproximate size, form and depth of this object.

The further the sound waves travel, the more they fan out into a cone shape and increase in diameter. Deeper water obviously causes the cone to become bigger as it goes out of it's origin. Whenever the sonar wave strikes against a good object of any substance, it will rebound an echo back to the transducer. The form of the object struck will be decided by how much time it took the signal to head out and then bounce the audio wave echo back in contrast to the surrounding area. The echo will subsequently show up on your fishfinder display and you'll see the aproximate dimensions, shape and thickness of the item.

Fishfinders use sonar technology to locate fish-or any other good object-under the surface of the water. Sonar sound waves move through the water. The farther the sound waves travel, the longer they fan out into a cone shape and increase in diameter. Deeper water naturally causes the cone to become bigger as it goes from it's origin. The form of the object struck will be decided by how much time it took the signal to head out and then bounce the sound wave echo back compared to the surrounding area. The echo will subsequently appear on your fishfinder display and you'll see the aproximate size, form and thickness of this object.
