What is CHIRP on a fish finder? CHIRP – or “Chirp” as it is sometimes called, is the acronym for Channelized High-Resolution Passive sonar. It is one of the most important new technologies in marine electronics and has been around since the early 1990s. The technology was developed by Dr. John Kiely at the University of Maine who received his Ph.D. from the Massachusetts Institute of Technology (MIT) under Professor Robert M. Whitehead. CHIRP uses an array of hydrophones to detect sound waves that are reflected off objects underwater. A technique like this lets you see what’s beneath the surface without diving into murky waters.
CHIRP can be used with any type of fishing equipment including:
- Fishing rods
- Fishing lines
- Rod holders
- Line holders
- Casting nets
- Fishing jigs
- Jigging hooks

How Does CHIRP Work?
CHIRP’s basic principle is very simple. It involves passing a small amount of electrical current through a wire, thereby creating a magnetic field that interacts with the earth’s magnetic field, causing the earth’s magnetic field to change. Sensors like magnetometers are used to detect changes in earth’s magnetic fields. If anything is nearby that causes these changes, the sensor will be able to detect them.
The sensor sends out pulses of electricity which travel through the water. Pulses encounter particles suspended in water as they travel through it. Some of these particles reflect the pulse back towards the sensor. By measuring how long it takes for the pulse to return to the sensor, we can determine where the object is located.
This process is repeated thousands of times per second allowing us to create a picture of what is below the surface.
Why Use CHIRP?
CHIRP is a great tool for detecting fish and other aquatic life. It provides accurate depth information so you know exactly where your bait is located. You also get a clear image of what is below the water’s surface.
CHIRP is especially useful when using lures because it helps you locate the lure before you cast. With CHIRP, you can tell if you have hooked a big bass or just a little minnow.
CHIRP is also very helpful when casting for trout. Trout are often found near the bottom of lakes and ponds. They like to hide in weeds and brush piles. CHIRP makes it easy to find them.
CHIRP works best in calm waters. In choppy seas, the signal may not be strong enough to pick up the fish. However, even in rough conditions, CHIRP still gives you a good idea of what is beneath the surface.
The CHIRP is a great tool for detecting fish. It is lightweight and small so it won’t take up much space on your boat. It is also easy to install and does not require any special skills. You’re sure to find CHIRP useful whether you’re a novice fisherman or just trying to improve.
