600 W
Airmar’s low-profile, Chirp-ready, transducer models are the perfect addition to 
smaller boats such as center consoles. Operating at a frequency range of 80 to 
130 kHz, the B75M delivers up to 50 kHz of total bandwidth in just one 
installation. This transducer shows amazing bottom detail in shallow and medium 
depths down to 274 m (900').
Tilted Element transducers™ have the 
ceramic element fixed at a 20°, 12°, or 0° angle within the housing. When the 
transducer is installed almost flush to the hull, the tilt of the element 
corrects for the hull deadrise, orienting the beam directly down. This ensures 
maximum echo returns to the transducer and more accurate depth readings.
The B75M is available in three Tilted Element models:
  - Fixed 20° 
  tilted version for 16 to 24° hull deadrise angles
- Fixed 12° 
  tilted version for 6 to 15° hull deadrise angles
- Fixed 0° 
  tilted version for 0 to 7° hull deadrise angles
 
  - 
  Depth and fast-response water-temperature sensing
- 
  600 W of power with a maximum depth of 274 m (900')
- 
  Medium frequency: 80 to 130 kHz
  
- 
  Medium frequency provides good shallow-water performance, bottom detail, and 
  deeper performance than high-frequency band
- 
  Low-profile, thru-hull housing delivers good display resolution at speed when 
  installed properly
- 
  Bronze housing for use in a fiberglass or wood hull
- 
  Recommended for stepped, planing, or displacement hull
- 
  Also available in a stainless steel housing (SS75M) for use in all hull 
  materials
- 
  Patented Xducer ID® technology

300 W
Airmar’s low-profile, Chirp-ready transducer models are the perfect addition to 
smaller boats such as center consoles. The low-frequency band, operating between 
40 and 75 kHz, is a deep-water performer, providing excellent coverage and 
tracking. The B75L transducer delivers up to 35 kHz of total bandwidth in just 
one installation.
This Tilted Element™ transducer has the 
ceramic element fixed at either a 12° or 0° angle within the housing. When the 
transducer is installed almost flush to the hull, the tilt of the element 
corrects for the hull deadrise, orienting the beam directly down. This ensures 
maximum echo returns to the transducer for more accurate depth readings.
The B75L is available in two Tilted Element models:
Fixed 20° tilted version for 16 to 24° hull deadrise angles
Fixed 12° tilted version for 6 to 15° hull deadrise angles
Fixed 0° tilted version for 0 to 7° hull deadrise angles
