Know before you buy
The 20-degree tilt compensates for the deadrise of your boat's hull. This ensures the sonar beam points straight down toward the bottom rather than at an angle, providing more accurate readings and better target separation.
Because this is a thru-hull transducer with a tilted element, it is designed to sit flush against the hull. You generally do not need a fairing block, but you should verify your boat's hull deadrise matches the 20-degree tilt for optimal performance.
Yes, the dual-frequency capability makes it versatile. The 50kHz setting is ideal for deep-water performance, while the 200kHz setting provides higher resolution and better detail in shallower waters.
This unit features a standard 9-pin connector designed for broad compatibility with Navico and compatible sonar displays. However, always check your specific display's manual to ensure it supports the HDI transducer pinout.
Bronze is significantly more durable and resistant to corrosion, making it the preferred choice for long-term use in saltwater environments. It provides a more robust, permanent installation for boats kept in the water for extended periods.
Yes, it includes a built-in temperature sensor. This allows your compatible display to show real-time water temperature readings alongside your sonar imagery.
