SI-TEX 494/50/200 In-Hull Transducer f/ES502

The SI-TEX 494/50/200 In-Hull Transducer for ES502 is a dual-frequency marine sonar transducer designed for anglers and boaters who require reliable bottom structure and fish detection without the need for drilling through the hull. This internally mounted transducer is perfect for fiberglass boats, providing a permanent installation that maintains the integrity of the vessel.

Engineered to operate at dual frequencies of 50 kHz and 200 kHz, the SI-TEX transducer allows users to switch between deep-water scanning and precise shallow-water detail based on their fishing conditions. The 50 kHz frequency is ideal for long-range penetration and structure mapping, while the 200 kHz setting offers high-resolution bottom imaging and baitfish returns in shallower waters. Its compact in-hull design ensures effective acoustic coupling through fiberglass, delivering solid signal transmission.

Serious anglers targeting species like walleye and striped bass will benefit from the imaging clarity provided by this transducer. It integrates seamlessly with the SI-TEX ES502 chartplotter, allowing for intuitive navigation and real-time sonar overlay. The internal hull mount installation method simplifies setup while minimizing the risk of leaks or structural weaknesses.
