R109LHW Low High Wide Chirp Thru-Hull Transducer with Fairing Block – No Connector
Get more coverage under the boat with Airmar’s unique wide-beam, low- and high-frequency, Chirp-ready R109LHW. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25-degree beam for all frequencies, which results in superior resolution. The constantly wide beam provides twice the coverage and clear fish arches on the display compared to most high-frequency, narrow-beam transducers.
The high-wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage under the boat are essentially down to 152 m (500′). The low-frequency band and 2 kW of power also support great deep-water performance. Get the best of both worlds with Airmar’s Chirp-ready transducer with wide-beam coverage.
Features:
- Depth and fast-response water-temperature sensing
- 2 kW of power for excellent deep-water performance from the low-frequency
- 2 kW low frequency (38 to 75 kHz): 19 to 10-degree port-starboard beamwidth; 10 to 5-degree fore-aft beamwidth
- Maximum depth of 1829 m (6000′)
- 1kW high frequency (150 to 250 kHz): 25-degree constant beamwidth; Maximum depth of 152 m (500′)
- 137 kHz of total bandwidth from one transducer
- Covers popular fishing frequencies of 50, 68, and 200 kHz plus everything else in the bandwidth
- High frequency delivers superior shallow-water performance, bottom detail, and fish-target separation
- High wide beamwidth yields more coverage for detecting fish in the upper-water column
