Airmar B175C-20-M-21HB Medium CHIRP 1kW 20-deg Tilt Thru-Hull Transducer Humminbird 21-Pin

1 kW

The 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 transducers have the element fixed at a 20 degrees, 12 degrees, or 0 degrees angle within the housing. Because the transducer is installed almost flush to the hull, the tilt corrects for the hull deadrise. It orients the ceramic element horizontally to ensure maximum echo returns to the transducer.

The B175M is available in three Tilted Element models:

• Fixed 20 degrees tilted version for 16 to 24 degrees hull deadrise angles
• Fixed 12 degrees tilted version for 8 to 15 degrees hull deadrise angles
• Fixed 0 degrees tilted version for 0 to 7 degrees hull deadrise angles

• Depth and fast-response water-temperature sensing
• 1 kW of power
• Medium frequency: 85 to 135 kHz
• 16 degrees to 11 degrees 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
