You can use a fish finder sonar, or have used, but you can not know exactly how it works. Sonar fish finder to take a picture of what can not be seen. Sonar stands for Sound Navigation and Ranging. It is used to show the contours and structures under water. You can also give readings depth.
Sonar works for a sound wave and the measurement of time, the return of the sound wave. It then converts the image information that is displayed on a screen. Thishappens very quickly. A sound wave can travel back 240 feet and in the second quarter. The image shows up and is scrolled on the screen as new images are available in a range of sonar. With this technique, a person can see on the screen, structures, and fish and even see the dimensions that are related.
These sound waves are transmitted at different frequencies. The higher the frequency will be more detailed results. But the depth of skills are less.Lower frequencies provide greater depth, but in less detail. Most fish finders operate from 200 kHz to 83. Some units have double-or triple-rate. Higher-end models use the "side imaging" function, a clear vision of a vast area of water around the unit does. This function uses the frequencies from 455 kHz to 800. Some sirens, two or more light beams of sound. The dual-beam of 20 degrees or close second, larger, capable of 60 degrees below theUnits.
Most fish finders are mounted on the ship in a comfortable position for the viewer. A power cord is used on inpatient units. This is a 12-volt battery system, usually the battery system connected to the boat. Portable devices use batteries, such as regular double A batteries or batteries for that model.
Fish Finder is available in many sizes and types with different bells and whistles. Many come with a combination of GPS, in addition to the sonar.Prices range from $ 80 to several thousand dollars. There are many brands to choose from. When shopping, make sure you do your research and get one that can meet all your needs.
