Sonar technology in the fish finders helps a lot to locate, mark and reach out the areas which have a high probability to find existing fishes.

Due to the fact, with the help of the different frequencies of the sound waves the fish finders which are equipped with high power sonar are capable of providing a clear view of what is there beneath the boat and its sides. It gives a complete picture of the underwater environment by showing the fish location without blurring issues.

Despite the fact that sonar fish finders work on the same principle and uses the same basic technology, a little twist in the way the frequencies are being used in the variously advanced fish finders allows providing different systems using the frequencies in various ways for better imaging and range enhancement.

Traditional sonar fish finders are the ones which offer sound frequency waves that consist of one type of frequencies instead of multiple types or ranges. This works fine when you have to target the fishes in a small area where you are familiar with the range and depth you are going to cover. The sonar fish finders with 50 kHz sound frequencies give maximum penetration but has lesser power and may not be able to provide detail. In contrast to this, you can expect better imagery when you are using the high-frequency waves of about 200 kHz but lesser penetration.

These traditional sonar fish finders may only offer a single type of frequency waves or some advanced versions may offer adjustability and multiple frequency options in some cases.

Down Imaging Sonar Fish Finder

Down imaging fish finder are able to each deep water bodies and give a clear image of what is found below. These kinds of fish finders are meant to be used in salt water and deep areas. They offer a wide range of frequency options depending on the kind of sonar fish finder you have.

CHIRP Fish Finder

CHIRP technology has revolutionized the way sonar fish finders work. Instead of using a single selected frequency of sound waves, CHIRP offers continuous sound waves of varying frequencies to get the message back, so that the whole area along with all the details is covered perfectly. This helps in getting detailed and high-quality imagery that lets the user find fishes more easily and get an idea of the environment below. There is no blur nor hindrance and no possible blockage of images when your fish finder has the CHIRP technology in it.

Sonar Combo Fish Finder

Some sonar fish finders come in combination with the GPS fish finders as well. Some may offer multiple frequency waves for better area coverage and detailed imagery. Such fish finders are good to use when you have planned to fish around in various areas with variable underwater conditions.
