Raymarine B275LH-W Bronze Thru-Hull - Low & High Wide Frequency
Raymarine B275LH-W Bronze Thru-Hull - Low & High Wide Frequency — Product description
Discover the power of superior underwater visibility with a transducer designed for serious anglers chasing big game in deep waters. This bronze thru-hull model delivers exceptional CHIRP sonar performance, blending low-frequency penetration for bottom structure with high-frequency precision for marking fish in the upper column. Perfect for offshore adventures or tournament fishing, it expands your scan area dramatically, revealing more targets without sacrificing clarity.
Why Choose Wide Beam CHIRP Technology?
Traditional narrow beam transducers leave gaps in coverage, but wide beam options sweep a broader area directly beneath your vessel. With a consistent 25-degree beam across the high-frequency range, you get double the bottom footprint compared to standard high-CHIRP models. This means spotting schools of baitfish, wrecks, or trophy catches that might otherwise slip by. Low frequencies punch through to 3,000 feet for structure scanning, while highs excel up to 800 feet for detailed pelagics.
- Twice the coverage for comprehensive bottom mapping
- Crisp, enlarged target returns for easier identification
- Rugged bronze housing withstands constant water exposure
- 1kW power handles demanding conditions
Technical Edge for Peak Performance
Engineered for thru-hull mounting on hulls up to 20-degree deadrise, this unit supports frequencies from 42-65 kHz low and 150-250 kHz high. The result? Versatile sonar that adapts to your fishing style—deep drops for grouper or snapper, or shallow scans for tuna push. Temperature sensing adds another layer, helping track water columns for thermocline edges where fish congregate.
Pair it with compatible sounders for seamless integration, turning your display into a fish-finding powerhouse. Anglers report seeing bait balls and individual hooks clearer than ever, boosting hook-up rates on long-range trips.
Seamless Thru-Hull Installation Tips
Mounting a thru-hull transducer requires precision for optimal beam projection. Select a flat spot forward of the propeller, away from strakes or intakes to minimize turbulence. Drill carefully, bed with marine sealant, and route the 6.6-foot cable neatly—consider extensions for longer runs. Fairing blocks help on steeper deadrises, ensuring the face stays perpendicular to the waterline for accurate readings. Professional installers love its straightforward setup, getting boats back on the water fast.
- Measure and mark hull location
- Drill pilot hole, then core out
- Apply sealant, thread thru-hull
- Secure and test alignment
Proven in the Toughest Waters
From bluewater canyons to coastal reefs, this transducer shines where others falter. Tournament pros use it to grid search wrecks efficiently, while recreational skippers enjoy weekend pelagics with confidence. Its bronze construction resists corrosion in saltwater, and the high-power output maintains clarity even at speed. Imagine dialing in on a 50-fathom ledge, watching marks stack up as you drift— that's the edge it provides.
"Switched to wide beam and immediately saw more fish holding tight to structure. Game-changer for deep dropping."

Longevity Through Smart Maintenance
Keep performance peaking with simple care: Rinse after every saltwater trip to flush debris, inspect the face for growth, and check cable connections seasonally. Avoid antifouling paints on the active face to prevent signal damping. With proper upkeep, it delivers years of reliable service in harsh marine environments.
Frequently Asked Questions
What makes the wide beam different from standard CHIRP transducers?
Wide beam maintains a constant 25-degree angle across the high-frequency band, doubling bottom coverage and producing larger, sharper fish arches compared to narrower beams.
What depths can this thru-hull transducer reach?
Low frequencies handle up to 3,000 feet for deep structure, while highs manage 800 feet for precise fish detection in shallower zones.
Is this suitable for boats with deadrise angles?
Yes, it supports 0 to 20-degree deadrise hulls, with fairing options available for optimal alignment.
Does it include temperature sensing?
Absolutely, built-in temperature sensor helps identify thermal breaks and water column details.
What power rating does it support?
Rated at 1kW, providing strong signal output for clear returns in varied conditions.
Can it be used for high-speed operation?
Bronze thru-hull design excels at displacement speeds; proper mounting minimizes interference at planing speeds.
What frequencies does it cover?
Low: 42-65 kHz for depth; High wide: 150-250 kHz for coverage and detail.

B275LH-W Bronze Thru-Hull - Low & High Wide Frequency
Get more coverage under the boat with the wide beam CHIRP product line. Offering a high frequency range of 150-250 kHz and a constant 25° beam width, these transducers are truly broadband at its best. In addition to improving the performance of CHIRP-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency CHIRP transducers.
A unique property of the high frequency transducers is that the beambwidth is a constant 25° angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with the narrow beam transducers, the wide beam format also creates crisper and larger return images on the display. We've got you covered!
