Garmin 010-11636-20 80-130KHZ 0D Tilt Bronze B75M TH 8P

The Garmin 010-11636-20 80-130KHZ 0D Tilt Bronze B75M TH 8P is a high-performance through-hull transducer engineered for serious saltwater and freshwater anglers who demand reliable sonar in demanding marine environments. This transducer represents the gold standard for structure mapping and fish detection, delivering dual-frequency capability that adapts to varying water conditions. Whether you're running a center console off the coast or a bay boat in shallow flats, this Garmin transducer integrates seamlessly with compatible fish finders to give you the detailed bottom imaging and target identification that separates productive days from empty ones.

Built with a bronze housing and designed for permanent through-hull installation, the B75M transducer operates across an 80–130 kHz frequency range, offering the flexibility to switch between broad coverage (80 kHz) and high-resolution detail (130 kHz) depending on your fishing situation. The zero-degree tilt design ensures optimal signal transmission when mounted vertically on the hull, minimizing interference and maximizing cone coverage directly below the boat. Its eight-pin connector (8P) provides a secure, standardized interface to Garmin fish finder systems, while the 6.11 lbs weight distributes load evenly without affecting hull performance or fuel economy. The bronze construction resists corrosion and galvanic degradation—critical factors in saltwater applications where equipment failure costs fishing time and money.

This transducer is ideal for anglers with Garmin echoMAP, GPSMAP, or compatible legacy systems seeking to upgrade or replace worn through-hull transducers. Professional guides, tournament competitors, and recreational anglers alike rely on this model for its proven ability to cut through thermoclines, detect suspended baitfish, and reveal hard-bottom structure where larger game fish hold. Installation requires a through-hull mounting location below the waterline with minimal turbulence; most 16–40 foot center console and bay boats offer suitable hull positions. Verify compatibility with your existing Garmin fish finder's eight-pin connector port before ordering to ensure seamless integration.
