CHIRP equals a sweep pattern of sound within a long-duration transmit pulse across a frequency range. The sound energy that goes into the water from CHIRP is many times greater than that emitted by traditional sonar. A CHIRP unit simply sends and receives a ton of information.Apr 24, 201
i copied this out of Sport Fishing Magazine for their definition. Alphahawk and Rickie can put it into better terms and might chime in on this. Chirp will give you a better pic on your depth finder than just a normal depth-finders due to,the fact it’s a stronger pulse sent out and back via the transducer. To me, it’s worth the additional cost.
