B175M Bronze 20 Degree Thru-Hull 1kW for Garmin with 8-Pin ConnectorThe B175M&&';;s 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. Medium frequency also provides excellent shallow-to-mid-depth performance, bottom detail, and fish-target separation. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths of up to 457 m (1500&';) and gives ultra-clear target resolution.Airmar&&';;s Tilted Element(TM) transducers have the element fixed at a 20Adeg, 12Adeg, or 0Adeg angle within the housing. Because the transducer is installed almost flush to the hull, the tilt corrects for the hull&';s deadrise. It orients the ceramic element horizontally to ensure maximum echo returns to the transducer.Features: Garmin 8-Pin Mix & Match Cable for Chirp Transducers Depth and fast-response water-temperature sensing 1 kW of power Medium frequency: 85 to 135 kHz 16Adeg to 11Adeg beamwidth Maximum depth of 457 m (1500&';) 50 kHz of total bandwidth from one transducer Low-profile, thru-hull housing provides good display resolution at speed when installed properly Recommended for stepped, planing, or displacement hull Bronze housing for use in a fiberglass or wood hull Also available in a stainless steel housing (SS175M) and a thru-hull (B285M) or in-hull (M135M) mount Patented Xducer IDA(R) technology Specifications: Power Rating: 1 kW Max Deadrise Angle: 24Adeg Housing: Bronze Functions: Depth, Temperature Hull Material: Fiberglass or wood Hole Size: Fiberglass or wood hull 95 mm (3-3/4"), Metal hull 105 mm (4-1/8") Usable Shaft Length: 55 mm (2.18") Mounting Style: Tilted Element Thru-Hull Acoustic Window: Urethane Common Use: Fishing Max Deadrise: Up to 24Adeg Max Depth: 457 m (1500&';) Medium Frequency: 85-135 kHz Medium Frequency Beamwidth: 16Adeg-11Adeg Retractable housing: No Single or Dual Frequency: CHIRP-Ready Single-Band Tilted Element: Yes Weight: 2.7 kg (6 lbs.)
