Tournament days demand flexibility. Successful captains and crews constantly adjust—changing baits, shifting locations, and refining tactics to gain an edge. Your transducer frequencies should be approached the same way: as adjustable tools that allow you to optimize sonar performance based on depth, structure, and target species.
As the leader in CHIRP transducer technology, AIRMAR offers a wide range of frequency band and beamwidth combinations, giving anglers precise control over how they view the water column. This adaptability is one reason competitive teams consistently rely on AIRMAR CHIRP transducers.
Expanding Medium-Frequency Performance
AIRMAR recently introduced a new medium-frequency (60–100 kHz) ultra-wide array that delivers exceptional coverage and performance.
Medium frequencies provide better target resolution than low frequencies, while still penetrating deeper than high frequencies—allowing detection of targets down to approximately 1,300 feet.
The primary advantage of this new array is its expansive beamwidth.
With port-to-starboard beamwidths ranging from 57° to 73°, it covers a significantly wider swath of water than traditional narrow-beam transducers. This broader coverage increases the likelihood of locating fish that might otherwise go undetected.
Layering Frequencies for Complete Coverage
Layering frequencies and beamwidths has become more streamlined. With just two transducers onboard, anglers can achieve comprehensive sonar coverage from the surface to the seafloor.
B275MWHW Thru-Hull (1 kW)
The New B275MWHW combines:
- 1 kW medium-frequency ultra-wide array (60-100kHZ)
- High-frequency wide beam (150-250kHz)
The high frequency features a fixed 25° beamwidth, excelling from the surface to approximately 500 feet, while the medium band extends effective detection down to 1,300 feet.
PM411LWM Pocket Mount (2 kW)
Pair it with the PM411LWM (2 kW Low-Wide/Medium) pocket mount, and you add:
- 40° low-frequency beam
- Depth capability up to 3,000 feet
The medium-frequency elements on this model are especially effective in shallower water when identifying fish holding tight to structure due to narrower beamwidths.
A Complete Offshore Sonar System
Together, these two AIRMAR CHIRP transducers create a flexible, highly adaptable sonar system—delivering:
- Broad search capability
- Deep-water penetration
- Detailed target separation
- Improved situational awareness
Only AIRMAR offers CHIRP transducers across all frequency bands with beamwidth options ranging from narrow to ultra-wide—allowing captains to choose one frequency or layer multiple bands to find fish wherever they hold.
