Raymarine Retractable Nylon TH Depth Transducer F/ST40/60

The Raymarine Retractable Nylon TH Depth Transducer F/ST40/60 delivers precise bottom-contact data to your sounder without the permanent hull penetration that traditional through-hull installations demand. Built for serious anglers and boaters who need dependable depth readings across fresh and saltwater environments, this retractable transducer combines convenience with the accuracy your navigation and fish-finding depend on. Whether you're working shallow flats, running deep offshore channels, or exploring unfamiliar water, having a transducer you can deploy and stow protects your vessel's integrity while maintaining the crystal-clear sonar imagery you need to locate structure and baitfish.

This nylon-hulled transducer is engineered to retract smoothly when not in use, eliminating drag, reducing noise in the water, and protecting the sensing element from impact and debris during high-speed runs or tight maneuvering. The retractable design works seamlessly with Raymarine ST40/60 series chartplotters and sounders, delivering real-time depth, temperature, and bottom-composition data via proven transducer architecture that has earned trust across commercial and recreational fleets. The robust nylon construction resists corrosion and UV degradation, while the transducer's geometry is optimized to cut through aerated water and maintain signal integrity even in challenging sea states or when navigating over sandy, muddy, or rocky bottom.

Anglers running center consoles, open boats, or trailerable vessels will appreciate the non-invasive installation and the ability to retract the transducer when launching, loading, or operating in extremely shallow water—critical advantages when every inch of draft matters or when protecting electronics from theft and weather. Installation pairs directly with Raymarine ST40 and ST60 systems, and the lightweight 2-pound transducer assembly minimizes weight distribution changes and vibration. If you're upgrading an existing Raymarine sounder or building a new glass-cockpit setup, this depth transducer offers field-proven reliability and the flexibility that modern boating demands.
