Airmar CHIRP
Technical details
Producer: Airmar Technology Corporation (USA)

Airmar Technology Corporation recently introduced a new line of broadband transducers that utilize compressed high-intensity radar pulse to improve the accuracy and clarity of modern fishfinders, giving anglers precise detail down to 10,000 feet.

The new technology, called CHIRP for short, scans and locates fish by sweeping through frequencies 28kHz - 210kHz within a long-duration transmit pulse from the company's new broadband transducer. The company says this method transmits 10-1000 times greater sound energy into the water than conventional fishfinder technology.

By pulsing more sound energy into the water, more echo energy is returned to the fishfinder, which is used by the digital signal processing computer in the finder to generate a sharper picture of what lies below the water.

Airmar CHIRP transducers can be found in Garmin GSD 26 and Simrad BSM-2 fishfinders, with more major manufacturers incorporating the technology into their products in 2012.
