TM185C-M-8G 1kW CHIRP-Ready Transom MountThe TM185M is a transom-mounted, Chirp-ready transducer designed for offshore fishing and freshwater anglers spending their time in shallow to mid-range depths. The medium frequency delivers the right combination of coverage under the boat, extended depth range, and the ability to produce clean and accurate target and structure returns in mid to deeper water. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths down to 457 m (1,500') and delivers ultra-clear target resolution.The TM185M transmits across the following bandwidth:Medium frequency 85 to 135 kHzFeatures:The depth and fast-response water-temperature sensor1 kW with a maximum depth of 457 m (1,500')Medium frequency: 85 to 135 kHz16Adeg to 11Adeg beamwidth50 kHz of total bandwidth from one transducerCovers popular fishing frequencies of 88 and 107 kHz plus everything else in the bandwidthMedium frequency provides excellent shallow to mid-depth performance, bottom detail, and fish-target separationTransom-mount, urethane housing with a stainless steel bracket for installation on outboard and I/O powered boatsAlso available as thru-hull (B285M, B175M) and in-hull (M135M) modelsExclusive Xducer IDA(R) technologySpecifications:Weight: 4.2 kg (9.2 lb.)Recommended Boat Length: Up to 10 m (32')Transom Angle: 3Adeg to 21AdegAcoustic Window: UrethaneIncludes: Adjustable, stainless steel bracket and mounting hardwareTransducer Element: One internal broadband ceramic assembly
