CHIRP Transducers vs Traditional Transducers

Author: The Marine Centre Editorial

Sounders work by transmitting frequency pulse, which hit the fish or other surface and rebound at the same frequency to be displayed by the sonars screens.

Compressed High-intensity Radiated Pulse (CHIRP) technology has been around for some time now - primarily used in sonars, radars, and military-grade laser systems.

Traditional non-CHIRP traditional transducers transmit one single frequency pulse at a time. In comparison, CHIRP transducers transmit a continuous sweep of high-intensity pulses ranging from low to high frequencies.

This difference makes it a game-changer in sonar technology.

Where a traditional sonar emitting a single frequency shows a school of fishes as a single blob or cluster, a CHIRP sonar individualizes each fish, making it much easier to distinguish between fishes and other surfaces.

To an experienced fisherman, this can even indicate the species of the fish.

Say, for instance, a 100kHz frequency signal is required to reach the surface with a pulse length of 90m. A traditional non-CHIRP transducer would not display any object nearer than this length as a separate object. However, since CHIRP transducers transmit a range of high-intensity frequency pulses, these pulses hit and rebound off of the nearer object with a different frequency than an object farther away - displaying each object separately.

The result is CHIRP sounders provide a greater separation and distinction between fishes and other objects.

And when combined with high-quality Fish Finders, they provide clearer, crisper, high-resolution images with a lot more information.

Our verdict, combine the CHIRP transducers with Fish Finders for better quality fishing.
