The Airmar B150M brings CHIRP broadband technology to anglers targeting medium depths in inland, freshwater, and coastal environments. Built around a bronze B619 housing, this 0-degree thru-hull transducer sweeps a 60 kHz band between 95 and 155 kHz, producing expanded beam coverage and sharp fish-arch definition on compatible echo sounders. Its fast-response temperature sensor and single internal ceramic element keep the profile straightforward without sacrificing performance.
