To answer this question, let us take an in-depth look at CHIRP on a fish finder.

What does a CHIRP on a fish finder mean?

CHIRP stands for Compressed High-Intensity Radar Pulse. This, as the name states, uses Radar pulses to offer a much wider and precise scanning vision for any fish finder, ultimately leading to an accurate and detailed fish view.

Firstly you need to know how to read a fish finder and the simple chirp sonar definition of it is CHIRP fish finders technology has quickly taken over the world and made fishing hours incredibly productive. It does so by scanning through variable frequencies and goes along on top of a fish finder, boosting its functionality and fish catching ability by a tremendous degree.

What are the benefits of using a CHIRP on a fish finder?

There is a long list of benefits of a CHIRP fishfinder, but the most crucial one is the sharp and high fish resolution it offers. Moreover, a high target separation degree helps distinguish objects beneath accurately and lets anglers fish at water depths as high as 10” deep. 

Additionally, CHIRPs on fish finders make scanning and tracking at high speeds possible and also make possible for the best ice fishing fish finders. All of these details together make up for the crispiest and detailed underneath view and increase the number of fishes caught while hunting.

How do you choose between different CHIRP ranges?

CHIRPs are available to the fishers in three different options. These CHIRPs can be chosen depending upon the type of fishing like (offshore fishing) and fish species the angler intends to hunt. Let us discuss the difference between these three types being high, medium, and non-CHIRPS.


High CHIRP consists of a frequency range between 150 to 240kHz. These are suitable for depths about 600 feet below and offer perfect tracking features for bait and game fishes.

Medium CHIRP:

Meanwhile, medium CHIRP uses a range between 80 to 160kHz and is the best fit for scanning much larger areas and fish arches. But it provides comparatively fewer details and accuracy than that offered by the High CHIRP.

Lastly, Non-CHIRP operates on frequencies between 50 and 200kHz. These reduce the accuracy of finders by a certain mark and offer only one percent duty cycle rate to the transducer.

Is CHIRP on a fish finder worth the money?

CHIRPS often becomes quite expensive and can be heavy on the buyer’s pockets when bought separately with a fish finder. Given this high investment, it is understandable that the angler finds himself questioning whether this CHIRP is worth the money spend on it or not.

The answer to this is definitely a yes! CHIRPS have revolutionized fish hunting and guaranteed a much better and productive fishing experience. Be it through its high-resolution view or high target separation, CHIRPS on a fish finder improve fish to catch while minimizing the angler’s effort and inconvenience.
