Garmin 010-11938-20 40-60KHZ 0D Tilt Bronze B175L TH 8P

The Garmin 010-11938-20 40-60KHZ 0D Tilt Bronze B175L TH 8P is a professional-grade through-hull transducer engineered for serious anglers and marine survey professionals who demand reliable sonar performance across variable water depths and conditions. This bronze-construction transducer delivers dual-frequency capability, making it ideal for both freshwater and saltwater applications where flexibility and accuracy are non-negotiable. Weighing 11.57 lbs, the B175L combines robust build quality with the proven Garmin engineering standard that powers commercial and recreational vessels worldwide.

Operating across the 40-60 kHz frequency range, this transducer achieves a balanced blend of sonar detail and depth penetration—ideal for mid-range to deep-water operation without sacrificing target definition. The 0 degree tilt configuration ensures optimal beam geometry for direct vertical scanning, critical for accurate bottom mapping and fish detection in structured environments. Bronze construction provides superior corrosion resistance in saltwater environments while maintaining structural integrity during installation and extended deployment, ensuring years of consistent performance even under harsh marine conditions.

The B175L TH 8P configuration is optimally suited for through-hull mounting systems on vessels ranging from commercial fishing platforms to serious recreational sport fishing boats. This transducer pairs seamlessly with compatible Garmin fishfinder and chartplotter units, delivering real-time sonar imaging for navigation, bottom profiling, and fish location. Installation requires professional through-hull mounting and proper transducer cable integration with your existing Garmin marine electronics system to ensure maximum frequency response and signal clarity.
