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 80-130 kHz Medium CHIRP frequency range with a 13-8° beam width. With Low CHIRP, the R111LM 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 R111LM simplifies installation and requires just one connection to your echosounder module or multifunction display.
With urethane housing, the R111LM is suitable for in-hull, pocket or keel mounting in solid fiberglass hulls.
In-hull or “shoot-thru-hull” transducers don’t require a hole to be drilled in your boat’s hull for installation, and offer good high-speed performance and ease of maintenance, but reduced maximum depth and fishfinding performance versus thru-hull, transom, or other in-water installations.
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.
