R109C-LH 2kW Thru-Hull TransducerCHIRP transducers enable bottom detection down to 3,000M (10,000') with 5 to 10 times greater detail and resolution so precise it's possible to distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to 117 kHz of total bandwidth in just one installation, saving customers time and money.As the HARD CORE model in the CHIRP Thru-Hull product line, the R109 LH/LM CHIRPS across the following bandwidths:LH Model - Low Frequency 38-75 kHz/High Frequency 130-210 kHzFeatures:Depth & fast-response water-temperature sensorLow: CHIRPS from 38 kHz to 75 kHz 19deg to 10deg port-starboard beamwidth (10deg to 5deg fore-aft beamwidth)High: CHIRPS from 130 kHz to 210 kHz 8deg to 4deg beamwidth117 kHz of total bandwidth from one transducerCovers popular fishing frequencies of 38, 50, and 200 kHz plus everything else in the bandwidthFishing Profile: Commercial and recreational inshore and offshore fishing (deep-water canyon and sea-mount tracking)Urethane transducer housing with High-Performance FairingBoat Size: 12M (40') and aboveHull Type: Fiberglass, wood, or metal
