TM275C-LHW 1kW Chirp Transom Mount TransducerGet more coverage under your boat with Airmar's unique wide beam, high frequency Chirp-ready transducers. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25Adeg beam for all frequencies. The high frequency band results in superior resolution. The constant wide beamwidth provides twice the coverage under the boat and excellent fish arches on the display compared to most high frequency narrow beam transducer options.The high wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage under the boat are essential down to 500'.The low frequency band and 1 kW of power also provides great deeper water performance. Get the best of both worlds with Airmar's dual frequency Chirp-ready transducers with wide beam coverage.Features:Depth and fast-response water-temperature sensor1 kW for great deep water performance from the low frequencyLow Frequency: 42 kHz to 65 kHz with maximum depth of 914 m (3000') 25Adeg to 16Adeg beamwidthHigh Frequency: 150 kHz to 250 kHz with maximum depth of 152 m (500') 25Adeg constant beamwidth123 kHz of total bandwidth from one transducerCovers popular fishing frequencies of 50 and 200 kHz plus everything else in the bandwidthHigh frequency provides superior shallow water performance, bottom detail and fish target separationHigh wide beamwidth provides more coverage under the boat for detecting fish in the upper water columnTransom-mount transducer with stainless steel mounting bracketRecommended boat size: up to 10 m (32')Hull Type: Fiberglass, wood, aluminum or steelExclusive Xducer IDA(R) technologyMix and Match Cable RequiredSpecifications:Weight: 4 kg (8.9 lb)Transom Angles: 3Adeg to 21AdegAcoustic Window: UrethaneUrethane transducer housing with stainless steel bracketEight internal broadband ceramic assemblies
