Garmin 010-11636-22 80-130KHZ 20D Tilt Bronze B75M TH 8P

The Garmin 010-11636-22 80-130KHZ 20D Tilt Bronze B75M TH 8P is a bronze through-hull transducer engineered for serious anglers and boaters who demand reliable sonar performance in freshwater and inshore environments. This dual-frequency transducer bridges the gap between deep-water scanning and high-resolution bottom detail, making it the workhouse choice for fish finders on vessels ranging from center consoles to cabin cruisers. Built to withstand years of saltwater and brackish-water exposure, this transducer delivers the accuracy needed to locate structure, thermoclines, and suspended fish with confidence.

Operating across 80–130 kHz frequencies, the B75M TH 8P transducer provides exceptional cone definition and target separation at both shallow and moderate depths. The 20-degree beam angle offers a balanced footprint—wide enough to cover productive water quickly, yet narrow enough to pinpoint structure with precision. Bronze construction resists corrosion far better than aluminum, ensuring long-term durability in aggressive marine environments. The 8-pin connector integrates seamlessly with Garmin's ecosystem of fish finders and chartplotters, while the tilt-angle design allows for hull mounting flexibility and optimized water contact on various boat geometries.

This transducer suits anglers who fish shallow-to-moderate depths and need visibility without constant readjustment. Professional guides, tournament competitors, and recreational boaters moving between lakes and coastal waters will appreciate its versatility and rugged construction. Installation requires a through-hull housing designed for 8-pin Garmin transducers; compatibility with existing Garmin systems ensures plug-and-play operation once properly mounted. Weighing 6.11 lbs, it installs without excessive structural demands while delivering sonar clarity that keeps anglers productive from sunrise to sunset.
