Airmar Technologies P75 Medium Chirp, 600W, M&M Transducer, DO | by West Marine

P75 Medium Chirp, 600W, M&M Transducer, DO600 W The P75M is a 600 W, Chirp-ready, in-hull transducer working on the medium-frequency band of 80 to 130 k Hz. This bandwidth is great for inshore saltwater as well as lakes and provides amazing target definition down to 274 m (900'). The major benefit of an in-hull transducer is no protruding features on the exterior of the hull, making it the perfect choice for trailered or lifted boats. Designed for smaller boats up to 8 m (25') with a solid fiberglass hull. The P75M includes a plastic mounting base which is aligned to the centerline and secured inside the hull. Then it is filled with non-toxic antifreeze. The transducer is inserted into the base and adjusted for the proper deadrise offset, ensuring the beam is shooting straight down for maximum echo returns. The eco-friendly coolant is the best medium to transmit through solid fiberglass and into the surrounding water.
