Advanced Features & Marine Applications
Bronze Thru-Hull Design Advantages
The bronze housing provides superior durability and corrosion resistance in harsh marine environments. Specifically engineered for fiberglass and wooden hulls, this thru-hull design eliminates turbulence issues common with transom-mounted units while providing consistent water contact at all speeds and sea conditions.
20° Tilted Element Engineering
The precision-angled tilted element ensures optimal sonar beam orientation for vessels with moderate deadrise angles. This design maximizes bottom coverage while maintaining accurate depth readings and fish detection capabilities in various sea states.
Professional CHIRP Technology
High-frequency CHIRP sonar technology delivers exceptional target separation, allowing you to distinguish individual fish even when they're positioned close to the bottom or grouped in tight schools. The continuous frequency sweep provides superior resolution compared to traditional single-frequency transducers.
