Raymarine B175LH 0DEG Pair Thru Hull Chirp Transducers Product Description
Unlock Superior Underwater Visibility with Dual CHIRP Power
Imagine gliding through coastal waters or chasing deep-water species, where every sonar ping reveals hidden structures, schools of fish, and precise bottom contours. This pair of thru-hull transducers delivers that edge by combining wide coverage with pinpoint accuracy, ideal for serious anglers and navigators who demand reliable performance in varied conditions.
Crafted from durable bronze housings, these transducers mount flush through the hull, minimizing drag while maximizing signal strength. The dual setup allows for simultaneous low and high-frequency operation, painting a complete picture from shallow reefs to depths exceeding 3,000 feet.
Engineered for CHIRP Excellence
The beauty of CHIRP technology lies in its ability to sweep across frequencies, producing clearer images than traditional fixed-frequency sonar. Each transducer in this pair features a low-frequency range optimized for deep-water penetration and a high-frequency band for sharp, detailed returns on baitfish and wrecks.
- Low-profile design: Zero-degree tilt ensures straightforward installation on flat hulls, reducing air entrainment and cavitation for cleaner signals.
- Bronze construction: Corrosion-resistant and robust, perfect for saltwater exposure over years of heavy use.
- Pair synergy: Deploy one for port-side scanning and the other starboard, or dedicate to split-channel sounders for non-overlapping coverage—no compromises on real-time data.
- Beam optimization: Narrow 0-degree beams focus energy straight down, excelling in bottom discrimination and high-speed tracking.
Users report exceptional target separation, even in thermoclines or heavy clutter, making it a go-to for tournament fishing or survey work.
Versatile Performance Across Marine Environments
Whether you're bottom bouncing for snapper in 500-foot depths or marking suspended tuna pods mid-water column, this transducer pair adapts seamlessly. The low band cuts through sediment for reliable hard-bottom reads, while high frequencies highlight subtle ledges and drop-offs.
In rough seas, the thru-hull placement stays submerged, delivering consistent pings without the interference common to transom mounts. Boaters upgrading from older single-band systems often note a dramatic improvement in fish-holding structure detection, turning guesswork into precision.
"Switched to this pair and finally see the fish arches I've been missing—game changer for offshore runs."
Pro Tips for Seamless Setup
Installing thru-hull transducers requires care, but the process rewards with lifelong reliability. Fair the base with marine sealant for a watertight seal, and align vertically using a digital level for optimal beam projection. Space the pair at least 3 feet apart to avoid acoustic crosstalk.
- Drill a precise hole sized to the transducer flange.
- Route cables away from engines and props to minimize noise.
- Test in calm water post-install to fine-tune gain settings.
For multihull vessels, the pair's flexibility shines, enabling independent mounts without hull distortion issues.
Longevity Through Simple Care
These transducers thrive with minimal upkeep: Wipe the faces clean after use to remove growth, inspect O-rings annually, and avoid antifouling paints on active surfaces. In biofouling-prone areas, a gentle vinegar soak restores clarity without damage.
Frequently Asked Questions
What hull types work best with these thru-hull transducers?
They excel on displacement hulls, planing boats, and sailboats with flat deadrise angles up to 12 degrees. Avoid steeply V-shaped hulls without deadrise kits.
Do I need both transducers in the pair for full CHIRP functionality?
Not always—one handles full dual-band CHIRP on compatible sounders. The pair unlocks simultaneous or split-channel scanning for advanced setups.
How deep can the low-frequency band detect targets?
Expect reliable returns beyond 3,000 feet in ideal conditions, with excellent performance down to 1,500 feet in most saltwater scenarios.
Are these transducers compatible with all Raymarine sounders?
They pair seamlessly with Axiom, Element, and Dragonfly series via 8-pin or 12-pin adapters, plus many third-party CHIRP-enabled units.
What's the main advantage of the 0-degree beam angle?
It provides a straight-down pencil beam for superior bottom detail and vertical resolution, outperforming wider angles in high-precision fishing.
Can I use these on freshwater boats?
Yes, the bronze holds up in freshwater too, though saltwater users benefit most from the anti-fouling design.
How do they handle high boat speeds?
Thru-hull mounting keeps them submerged up to 35+ knots, minimizing aeration compared to surface-piercing alternatives.
