Imagine slicing through choppy offshore waves in your center console, confident that every sonar ping reveals hidden structures, schooling fish, or that trophy catch hugging the bottom. The Raymarine A80046, a low-profile thru-hull transducer from the B175 series, steps up as a game-changer for serious anglers and boaters chasing medium-depth targets. Its medium CHIRP technology sweeps across 80-130 kHz, blending wide coverage with razor-sharp target separation—perfect for spotting gamefish amid bait balls down to 1,500 feet.
What sets this transducer apart isn't just the specs; it's how it performs in real-world chaos. The hydrodynamic bronze housing hugs the hull at high speeds without drag, while the adjustable deadrise compatibility (8-15 degrees) ensures flawless installation on most planing hulls. Whether you're drifting reefs or trolling bluewater, this 1kW powerhouse delivers fish arches that pop and bottom details that inform every decision.
Boaters swear by the B175M model (A80046) for its balance of power and precision. Here's what makes it shine:
Skip the guesswork—anglers report doubling their hookups on structure-bound species thanks to the superior target ID that cuts through thermoclines and bait clouds.
In coastal runs, the A80046's CHIRP sweep highlights baitfish schools with pinpoint accuracy, helping you position lures right in the strike zone. Push offshore, and its deep-tracking low-end grabs bottom contours at 1,500 feet, revealing snags or drop-offs that hold big pelagics.
For high-speed tournament pros, the thru-hull mount vibrates less than in-hull alternatives, preserving echo quality during long runs. Pair it dual-band with a high-frequency model for all-depth dominance, and you'll see why it's a staple on competitive center consoles.
Pro tip: Fairmount it dead-level to maximize beam efficiency—poor alignment can shave 20% off your effective range.
Installing the A80046 thru-hull is straightforward for DIYers with basic tools: drill, seal with marine-grade bedding compound, and route the cable away from engines to dodge interference. Its 12-degree standard version fits most V-hulls out of the box.
Maintenance keeps it humming: Annual freshwater flushes prevent marine growth, and inspecting the ceramic face for nicks ensures peak performance. With proper care, expect years of trouble-free service backed by Raymarine's commitment to quality.
The A80046 operates in the medium CHIRP range of 80 to 130 kHz, ideal for detailed imaging at medium depths up to 1,500 feet.
Yes, its low-profile design is perfect for center consoles and planing hulls, maintaining performance at speeds over 40 knots with minimal drag.
It features a variable beam width of 24 to 16 degrees, compatible with hull deadrises from 8 to 15 degrees for optimal coverage.
Rated at 1,000 watts, it reliably tracks targets down to 1,500 feet, delivering strong signals for offshore exploration.
The transducer comes with a 33-foot cable, providing ample length for routing through most hulls without extensions.
It's a thru-hull mount, designed for flush installation below the waterline for the cleanest sonar readings.
It integrates seamlessly with Raymarine CHIRP-enabled multifunction displays like Axiom and Element series for full sonar functionality.
B175 low-profile, CHIRP-ready transducers designed for high-speed applications such as center consoles. The B165 can be used individually or in pairs with Raymarine CHIRP sonars. The B175L transducer has up to 20 Kilohertz of total bandwidth and transmits across 40 to 60 Kilohertz bands. The CHIRP low-frequency band is a deep-water performer delivering excellent coverage and tracking. The B175M CHIRP medium frequency version operates at a frequency range of 85 to 135 Kilohertz. The B175M reveals fish at medium depths of up to 457 Meter (1,500 Feet) and delivers ultra-clear target resolution. The B175H transducer, a high-frequency CHIRP transducer, delivers a narrow beam width—excellent for pinpointing fish tight to wrecks and reefs. High frequency provides excellent baitfish and schooling gamefish target separation. The B175H has up to 80 Kilohertz of total bandwidth for superior shallow-water performance and bottom detail. The B175H is a high-frequency, wide-beam transducer operating across a frequency range of 150 to 250 Kilohertz with a fixed 25 Degree beam. The wide beam provides twice the coverage and excellent fish arches compared to narrow-beam transducer options. The B175HW CHIRP transducers are ideal for coastal and offshore fishing, offering excellent resolution and maximum coverage down to 152 Meter.
