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°, 12°, or 0° 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° 
  tilted version for 16 to 24° hull deadrise angles
- Fixed 12° 
  tilted version for 8 to 15° hull deadrise angles
- Fixed 0° 
  tilted version for 0 to 7° hull deadrise angles
