What Does the CHIRP mean on a fish finder?

What does the CHIRP stand for on a fish finder? This is a new adjustment on my new fish finder. What is CHIRP sonar vs. regular single frequency sonar. I've had 2 frequencies in the past for my cone angle. Ive read a little but I'm still pretty confused with the verbiage. Can anyone break it down for me in terms a 5 year old would understand lol.

  • CHIRP in a fish finder stands for Compressed High Intensity Radar Pulse. What it does is basically scan a broader range in kHz where other fish finders may have to select their workable range. CHIRP sonar sends a longer pulse which puts more energy into the water column giving you a better image. More energy equals more frequency range sent into the water. All of this means more data to create an improved image.
