Raymarine B175MH 20DEG Pair Thru Hull Chirp Transducers Product Description
Upgrade your vessel's sonar capabilities with the precision-engineered Raymarine B175MH 20-degree thru-hull CHIRP transducer pair. Designed for serious anglers and navigators who demand crystal-clear underwater imaging, this duo delivers exceptional target separation and coverage in medium to high frequency ranges. Whether you're chasing trophy fish in shallow coastal waters or mapping structure in deeper zones, these transducers provide the reliable performance that turns good outings into legendary ones.
Standout Features for Superior Sonar Performance
- Wide 20-Degree Beam Angle: Optimally balances coverage and resolution, ideal for spotting bait schools and individual game fish without overwhelming clutter from the bottom.
- CHIRP Technology Across Bands: Operates seamlessly in Medium (95-155 kHz) and High (150-250 kHz) CHIRP frequencies, unlocking detailed fish arches and precise depth readings up to 3,000 feet in optimal conditions.
- Thru-Hull Mounting: Flush installation minimizes drag and turbulence, ensuring clean hydrodynamics while capturing undistorted sonar returns from directly below your hull.
- Durable Airmar Build: Constructed with high-impact urethane housing that withstands harsh marine environments, from pounding waves to biofouling threats.
- Pair Configuration: Dual transducers for port and starboard redundancy, enhancing redundancy and multi-display compatibility on Raymarine multifunction displays.
Real-World Advantages for Boaters and Anglers
Imagine threading through rocky inlets with confidence, thanks to hyper-accurate bottom contouring that reveals hidden ledges and drop-offs. This pair excels in transitional zones where fish stage—think river mouths or nearshore reefs—delivering fish ID at speeds over 30 knots without signal loss. Skippers report fewer false readings compared to single-band transducers, leading to more hookups and less guesswork. Its fairing block compatibility streamlines retrofits on planing hulls, preserving speed and fuel efficiency.
"Switched to these from older bronze units, and the clarity on wrecks is night and day. Fish hold tight, and we mark them every pass." – Experienced offshore captain
Pro Tips for Seamless Installation and Setup
- Site Selection: Choose a spot forward of the propellers and strakes, at least 1/3 of the hull length from the stern, for minimal interference.
- Angle Matters: Deadhead the transducer at a 12-18 degree forward tilt to match your hull's deadrise, ensuring the beam points straight down at speed.
- Pairing Protocol: Connect via Raymarine's Axiom or A-series networks; calibrate gain and range post-install to match your vessel's conditions.
- Maintenance Hack: Annual epoxy barrier coat application prevents marine growth, extending ceramic element life.
- Compatibility Check: Integrates flawlessly with Element, Axiom Pro, and legacy HS units—verify your sounder module supports wideband CHIRP.
Professional installers note that proper fairing alignment reduces air entrainment by up to 40%, boosting high-speed performance.
Perfect Applications Across Marine Pursuits
From tournament bass boats scanning submerged timber to sportfishers hunting pelagics over seamounts, this transducer pair shines. Kayak anglers appreciate the compact 175mm size for trailerable crafts, while commercial operators value the ruggedness for all-weather ops. Pair it with SideVision for 3D wreck scanning or DownVision for live bait tracking—versatility defines its edge.
Frequently Asked Questions
What frequency ranges does the Raymarine B175MH support?
It covers Medium CHIRP (95-155 kHz) and High CHIRP (150-250 kHz), providing versatile imaging for various depths and targets.
Is this transducer suitable for high-speed boating?
Yes, the thru-hull design and 20-degree beam maintain strong signals at planing speeds, minimizing cavitation issues.
Can I use this pair with non-Raymarine fishfinders?
It pairs best with Raymarine systems via HS/Airmar connectors, but check your sounder for wideband CHIRP compatibility.
What's the maximum depth capability?
Up to 3,000 feet in high CHIRP mode under ideal water conditions, with excellent resolution down to 10,000 feet in medium band.
How do I clean and maintain the transducer?
Wipe with a soft cloth and mild soap; avoid abrasives. Apply anti-fouling paint sparingly to the face for long-term protection.
Does it require a fairing block?
Recommended for hulls over 16 degrees deadrise to optimize beam projection and reduce drag.
