Airmar’s exclusive wide beam transducers features a constant 25 degree beam angle for the entire High CHIRP spectrum. The result is improved shallow water coverage while maintaining the high resolution capabilities associated with the High CHIRP channel. Available in a variety of configurations, there is a wide beam transducer solution for almost any vessel. *All wide beam products come with a 2M pigtail off the transducer. Pair with a CHIRP Transducer Extension Cable (3, 5 or 10M) for a complete transducer installation.
