A huge catch is definitely the main objective for every angler. A Compressed High-Intensity Radiated Pulse (CHIRP) sonar is a powerful bottom-tracking and a fish finder that will greatly help you increase your catch success. This article will go in-depth about how you can use a CHIRP sonar and a CHIRP sonar is worth it for you.

Noise Reduction

Compared to traditional sonar, a CHIRP sonar reduces noise and increases the resolution of the transducer. By using an extensive range of frequencies, a CHIRP sonar vibrates at low frequency thus exceeding most limitations of a single-frequency standard sonar. It sends a longer pulse, puts more energy into the water column, and also produces a clear broadband frequency ranging up to 117 kHz.

Pulse Density and Pattern Correlation

For pulse compression and the pattern correlation, it transforms an extended frequency-coded pulse in a confined pulse of an extended amplitude. With increased power, this confined pulse can be linked from an extended pulse with the low peak power to enhance the range resolution and improve the signal to noise ratio. This will then enable the device to pull the target from the background noise with ease.

In-Depth Fish Information

Apart from providing you with explicit images, a CHIRP sonar will give you a clear structure of the fish you are targeting.

A downscan sonar shows you the exact picture and precise details of the fish. However, since it gives a minimal detail, there may be chances you might miss important information if you don’t pay close attention.

Traditional sonar is effective in showing you extensive fish details hence making it difficult for you to miss. However, it doesn’t show a clear picture of what is below the boat.

A CHIRP sonar creates a very higher resolution image and provides a greater target separation. A CHIRP sends continuous frequencies that provide the sonar with a wide range of information. It receives and processes huge amounts of data and displays this information in clear detail to achieve unprecedented resolution and vivid details of the targets. This information helps provide a more accurate, detailed structure of a fish and what’s underneath the boat.

Image Clarity

A CHIRP sonar comes with image clarity. Without a CHIRP sonar, you may just see random schools of fish on your locator.  The clarity improves to where you can differentiate the size of an individual fish in a school or a school of perch from a school of bass. 

This clarity will also help anglers understand how game fish relate to baitfish. When a predatory fish associates itself with a baitfish, it can be hard to distinguish them from the image of the bait. By utilizing multiple frequencies, CHIRP will allow you to see those predatory fish even if they are inside a ball of bait or directly under it. This will greatly work especially for people who like fishing offshore. It offers an in-depth view of the relation between gamefish and baitfish. Using a CHIRP on a fish finder will eliminate the issue of unclear imaging.

Clear Water Column Presentation

A CHIRP sonar also offers a clear representation of the water column. It vividly gives an unparalleled illustration of the water column. This helps differentiate between your bait and weight while drop shotting. As a result, you will have a full idea of how bass responds to their baits. CHIRP sonars also transmit a longer pulse than traditional sonars hence putting more energy into the water column. They transmit ascending pulses that are ten times longer in duration. This puts more energy into the water, 10 to 50 times more, creating a detailed water column image.

Increased Target Separation

For an increased catch, a CHIRP sonar will also aid in target separation. Achieving target partings of at most 2 inches (5.08 cm), it makes it easier to see the difference between your load and bait during drop shooting. Through this, fishers receive an improved knowledge of how bass reacts to your bait. This will then deliver you a massive shot with the vertical fishing crowd.

Convenient in Shallow Waters

Unlike the common myth, a CHIRP Sonar can also be used when fishing on shallow waters. Fishing from a stationary point just above a brush pile so as to allow you to track fish better as they go through the cover. Using a thermo-line, in this case, will significantly reduce the sensitivity.

CHIRP Sonar for Different Depths

Investing in a good quality CHIRP Sonar will let you see two CHIRP frequencies on screen at once. This will help you sweep a broad cone on the medium frequency CHIRP band. Depending on the depth, different CHIRP frequencies will work more effectively.

For freshwater anglers, fishing in depths greater than 10 feet, a low CHIRP below 80 kHz is highly effective for such depths. It will improve bottom tracking at higher speeds, offer you great performance, and also mark targets at such depths in the water column.

For depths less than 600 feet, a high CHIRP is recommendable.  It is also useful for both inland and freshwater. It will help you in lure tracking, identifying game fish and baitfish targets, and also targeting game fish near the bottom structure.

Medium CHIRP will work best for depths less than 600 feet with a range of 80-160 kHz. This CHIRP displays a wide coverage area, scans large areas quickly, and shows larger fish arches. Although, it is less detailed for smaller objects compared to a higher CHIRP setting.

Non-CHIRP or low CHIRP is great for deep water over 600 feet. This operates at frequencies below 80 kHz. Transmit pulse is only at such frequency. It will provide you with an amazing depth performance for up to 10,000 feet and also mark targets at all column depths in the water column.

Lowrance CHIRP Sonar Basics

In conclusion, a CHIRP sonar will help you make most out of your fishing experience. With a clear representation of the water columns, clear image clarity, and an in-depth view; it will greatly make your fishing easier and effective. Invest in a CHIRP sonar for an increased catch.
