CHIRP
Sonar Technology

What is CHIRP?

CHIRP is the most sophisticated sonar technology available for use by the fishing and boating public. The word itself is an acronym for Compressed High-Intensity Radiated Pulse.

Standard Sonar

Standard sonar sends 1 single frequency at a time. Since the only feedback is from this 1 single frequency, there is little information to work with, limiting the clarity and resolution available with standard sonar.

CHIRP Sonar

Instead of sending just 1 single frequency, CHIRP sends a continuous sweep of frequencies ranging from low to high. CHIRP sonar technology then interprets frequencies individually upon their return. Since this continuous sweep of frequencies provides CHIRP with a much wider range of information, CHIRP sonar is able to create a much clearer, higher resolution image.

Advantages of CHIRP

CHIRP has the power and processing sensitivity to deliver much better target resolution, clarity and crispness than any standard sonar system.

CHIRP Scanning Sonar

CHIRP technology also enhances the performance and clarity of Garmin DownVü and SideVü scanning sonar to provide the clearest sonar images on the water.
