Raymarine Lexan Depth Transducer f/ST60 & ST290

The Raymarine Lexan Depth Transducer for ST60 and ST290 is a P19 plastic low-profile through-hull transducer designed for reliable depth measurement on both metal and fiberglass hulls. Operating at 200 kHz, this transducer delivers the precise bottom-tracking data offshore anglers and serious boaters depend on for safe navigation and fish location, all without requiring a large hull cutout.

The transducer features a 2-inch installation diameter and arrives with 45 feet of cable, allowing flexible mounting options on boats of various sizes. The 200 kHz frequency provides good resolution in moderate to deeper water, balancing sensitivity with the stable readings needed for navigation and fish detection. Its low-profile design minimizes drag and reduces the visual footprint compared to traditional through-hull transducers. This unit is compatible with Raymarine's ST60+, i50, and ST70/i70 depth pods—though ST70 and i70 compatibility requires the ST70 depth pod or ITC5 interface sold separately.

Weekend fishermen upgrading legacy Raymarine systems and professional charter operators benefit from this transducer's straightforward integration into existing networks. Installation on either metal or fiberglass hulls means compatibility across diverse boat types, from aluminum runabouts to traditional fiberglass center consoles. If you're maintaining or expanding a Raymarine depth-finding system, this OEM transducer ensures sensor accuracy without compromising hull integrity or aesthetics.

Raymarine depth transducers are engineered for saltwater and freshwater operation, and this model's Lexan construction resists corrosion and impact. Pairing this transducer with your Raymarine chartplotter or multifunction display provides real-time depth data critical for coastal navigation, reef fishing, and avoiding shallow water hazards.
