Instead, you should use arch thickness to judge fish size.

A rch length doesn’t correlate with fish size, it simply indicates that a particular fish spent a long time swimming through your sonar cone. Many anglers mistakenly believe that a longer arch signifies a bigger fish, but this is incorrect. In that case, there are several things you can do to check if your transducer is working or not. If you have a CHIRP fish finder, and aren’t getting clear signals like this, your transducer may not be working properly.

This feature is ideal if you’re a beginner, and not sure how to tell which signals correspond to fish. Basically, if you enable this function, the fish finder will automatically interpret the arches and label them as fish for you, so you don’t need to worry about getting it right. Most fish finders nowadays have what’s called “Fish ID” technology. So you have to get some practice identifying all of these different types of arches as fish. This happens if the fish aren’t moving through the cone. Sometimes they look more like half arches, or more like short lines. For more information on the sonar cone read our article on how fish finders work.įish arches can be very diverse in size, length and shape.

There are two basic ways to do this:įish show up as arches on a CHIRP display due to the fact that they tend to move through the sonar cone, and therefore cast back a slightly different signal depending on where on the cone the sonar signal encounters them, which results in an arched line on your display. The most important aspect of using a CHIRP fish finder is the ability to use it to reliably identify fish close to your boat. While reading CHIRP sonar is similar to reading regular 2D sonar, it also has clear differences (for more details on this, check out our article on how to read a fish finder).

However, by using several different frequencies in combination, it’s possible to compensate for these differences, which results in a more complete picture, plus better object separation. Since every object underwater has a slightly different consistency, it responds differently to a single frequency of sonar. Table 2: CHIRP sonar relies on a combination of frequencies, which can range from 42 to 250 kHz, depending on the water depth. Low frequency 2D sonarĬone size Wide cone, 27 degrees Medium cone, 20 degrees Narrow cone, 13 degrees Water depth > 300 ft.

deep, the frequency is usually 200 kHz (see table 1 below), which covers most freshwater and inshore applications. The exact wavelength used by traditional 2D sonar depends on the depth of water in which you want to use it. So, if you’re wondering, what is the difference between CHIRP and traditional sonar, it’s this: while traditional 2D sonar relies on a single frequency to gather sonar information, CHIRP sonar uses a combination of different frequencies to gather more complete and more detailed information. What is CHIRP sonar?ĬHIRP stands for Compressed High Intensity Radar Pulse, and is not actually a separate sonar technology, but rather an improved version of traditional 2D sonar. In this article we’ll show you how to read CHIRP sonar, which is one of the most powerful sonar technologies available for fish finders.

If you want to take advantage of the full potential of fish finders to help you catch more fish, you need to understand the basics of sonar signaling, and how you can use different types of sonar for your specific needs. However, they come in a bewildering variety of models, each with different specifications, and with different combinations of sonar technologies. Fish finders help anglers catch more fish.
