Dual Channel CHIRP
Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers target resolution and depth penetration superior to traditional single-frequency sonar. This dual-channel CHIRP transducer operates in the 38-75 kHz Low CHIRP frequency range with a 19-10° beam width, and the 130-210 kHz High CHIRP frequency range with a 8-4° beam width. With Low CHIRP, the PM111LH provides an operating depth of up to 1200 m (4000 ft).
One sensor does it all. Able to measure both depth and temperature in a single package, the PM111LH simplifies installation and requires just one connection to your echosounder module or multifunction display.
With urethane housing, the PM111LH is suitable for pocket or keel mounting in solid fiberglass hulls. Pocket- or keel-mounting installs the transducer flush to the hull in a custom pocket, providing minimal drag and good high-speed performance. Boat builders may incorporate this transducer in new hulls, and aftermarket installation is possible by routing a suitable hole and fiberglassing the transducer in place.
