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 37-75 kHz Low CHIRP frequency range with a 19-10° beam width, and the 150-250 kHz High CHIRP frequency range with a 25° beam width. With Low CHIRP, the R109LH-W provides an operating depth of up to 1200 m (4000 ft).
Wide Angle CHIRP
Ideal for anglers, the R109LH-W’s wide-angle technology delivers a constant 25° beam width across the transducer’s 150-250 kHz High CHIRP frequency range. This achieves up to double the coverage beneath your boat, and provides enhanced fish detection in the upper water column, versus the narrower beam of other high-frequency CHIRP transducers.
One sensor does it all. Able to measure both depth and temperature in a single package, the R109LH-W simplifies installation and requires just one connection to your echosounder module or multifunction display.
With urethane housing, the R109LH-W is suitable for thru-hull mounting in fiberglass, wood and metal hulls. Thru-hull mounting places the transducer in the water on the outside of your boat’s hull; a hole must be drilled for installation, and a fairing block is required to ensure proper alignment. This typically offers the best depth measurement and fishfinding performance.
