Revolutionary Transducers Deliver Up to 73° Beamwidth for Unprecedented Sonar Coverage
FOR IMMEDIATE RELEASE
Milford, NH – September 2, 2025 – AIRMAR® Technology Corporation, a global leader in ultrasonic transducers and Chirp technology, announced the addition of two new dual-frequency models to its line of medium frequency ultra-wide beam transducers. These latest models combine powerful performance with innovative design, offering unmatched sonar coverage for anglers and commercial users alike.
Concave Ceramic Array Technology
Each of the new 1 kW models features Airmar’s revolutionary concave ceramic array, delivering an exceptionally wide beamwidth of up to 73° port/starboard in the medium frequency range (60–100 kHz). This ultra-wide beam allows for significantly greater underwater coverage than traditional transducers. Additionally, the high frequency range (150–250 kHz) provides a 25° beamwidth, ideal for detecting smaller targets with high-resolution detail.
Together, the medium and high frequency capabilities of these models provide optimal performance from shallow waters down to 1,300 feet (400 meters)—making them perfect for anglers targeting fish, especially pelagic species which can roam mid water column.
Two New Model Options
B275MWHW – Bronze Thru-Hull Model
- Bronze thru-hull construction for permanent installation
- High-speed fairing block included
- Professional installation recommended
TM275MWHW – Transom-Mount Model
- Rugged urethane housing for durability
- Adjustable stainless-steel bracket for transom angles up to 21°
- Flexible installation options
Revolutionary Coverage Capability
“Anglers who target fish from just below the surface to depths beyond 1,000 feet have never had access to this amount of coverage around their boat,” said Jennifer Matsis, Vice President of Sales and Marketing at Airmar. “A beamwidth of up to 73° in the medium frequency range, and 25° in the high frequency range, means you’re covering a massive area—while still achieving excellent target resolution on your fishfinder.”
Technical Specifications
Medium Frequency Performance (60–100 kHz):
- Beamwidth: 57° to 73° (port/starboard)
- Average: 16° (fore/aft)
- Maximum depth: 1,300 feet (400 meters)
High Frequency Performance (150–250 kHz):
- Beamwidth: 25°
- Maximum depth: 500 feet (152 meters)
Additional Features:
- Fast-response water temperature sensor
- Xducer ID® technology for automatic transducer recognition
- TM275MWHW: Adjustable stainless-steel mounting bracket
- B275MWHW: High-speed fairing block included
Broad Compatibility
These new models are compatible with Furuno, Raymarine and Humminbird Chirp-enabled fishfinders, with more manufacturers to be supported late in 2025. Customers are advised to check compatibility with their electronics manufacturer.
Flexible Ordering Options
Both models are available with:
- OEM connectors for direct installation
- Mix and Match™ transducer option with 9-meter (29’5″) cable and common plug
- 1-meter (3′) adapter cable matched to specific fishfinder models
Perfect for Pelagic Species
The combination of medium and high frequency capabilities makes these transducers particularly effective for targeting pelagic species that roam the mid water column. The ultra-wide coverage ensures anglers don’t miss fish swimming outside traditional narrow beam patterns.
Advanced Sonar Technology
Key technological advantages:
- Concave ceramic array design for maximum beam width
