Maximum Coverage Wide-Beam CHIRP Performance
The Raymarine B275LH-W wide-beam CHIRP transducer (A80322) is engineered to deliver significantly greater coverage under the boat compared to traditional narrow beam CHIRP models.
• High frequency CHIRP range: 150–250 kHz
• Low frequency CHIRP range: 42–65 kHz
• 123 kHz of total bandwidth from one transducer
• Constant 25° beam width across entire high-frequency band
• Covers traditional 50 kHz and 200 kHz fishing frequencies
• Wide beam delivers nearly twice the coverage under the boat
• Produces larger, crisper return images on compatible displays
Unlike variable beam transducers, the constant 25° high-frequency beam provides consistent upper water column coverage and improved fish target separation.
Offshore & Deep-Water Capability
Designed for serious anglers running CHIRP-ready echosounders.
• 1kW RMS power output
• Maximum depth capability: 3000 ft
• Optimized for boats 8 m (25 ft) and above
• Ideal for offshore, sportfishing, and deep-water applications
• Enhances CHIRP sonar clarity and bottom definition
Durable Bronze Thru-Hull Construction
Built for long-term marine installation and harsh saltwater environments.
• Bronze housing for durability and corrosion resistance
• Thru-hull mounting style
• Suitable for fiberglass or wood hulls
• Hull deadrise compatibility: up to 20° with fairing
• Urethane acoustic window
• Weight: 7.3 kg (16 lbs)
Bronze construction ensures strength and long-term reliability in offshore conditions.
Depth & Temperature Sensing
• Reads depth
• Integrated water temperature sensor
• No speed sensor included
Provides accurate bottom tracking and temperature data for serious fishing applications.
Installation Requirements
• Mounting style: Thru-hull
• Requires extension cable A80327 (not included)
• Fairing block required for proper deadrise installation
Professional installation recommended for optimal performance.
