Description
Raymarine CHIRP Tilted Element Thru‑Hull Transducer Series
Premium AIRMAR® 1 kW and 300 W Depth & Temperature Sensors
Built on AIRMAR’s innovative Tilted Element™ technology, Raymarine’s CHIRP‑ready thru‑hull transducers offer a low‑profile design that delivers outstanding depth performance and fish‑target separation without sacrificing speed or accuracy. Each model features patented Xducer ID® technology for automatic recognition and optimal CHIRP tuning when paired with compatible Raymarine sounders or AIRMAR modules.
Designed for anglers and boaters who demand uncompromising clarity and reliability, these tilted element sensors correct for hull deadrise, ensuring the acoustic beam is always vertically aligned for maximum echo return and accuracy.
