Raymarine Nylon Depth TH For: ST30 ST60 Instruments

The Raymarine Nylon Depth TH transducer for ST30 and ST60 instruments is a reliable through-hull sounder that puts accurate depth readings and fish-finding capability at your helm. Built for serious anglers and cruising boaters who demand consistent performance in variable conditions, this low-profile transducer integrates seamlessly with legacy Raymarine instrument systems, delivering real-time bathymetric data and target definition without unnecessary bulk or installation complexity.

Operating at 200 kHz, this nylon-hulled transducer provides the frequency sweet spot for medium-depth marine use, balancing range with target resolution across freshwater and saltwater environments. The 45 feet of pre-terminated cable eliminates splicing uncertainties and speeds installation, while the plastic low-profile housing reduces drag and minimizes turbulence around the mounting area—critical for boats that demand clean water flow and minimal noise signature. Raymarine's proven manufacturing ensures consistent beam patterns and signal clarity from idle to wide-open throttle.

This transducer is engineered for boats running ST30, ST60, ST60+, ST70, or ST290 display instruments, making it the go-to upgrade or replacement for anglers and boaters with established Raymarine systems who want to avoid rip-and-replace scenarios. Through-hull mounting requires a clean, flat deadrise-appropriate location below the waterline, and the supplied cable length accommodates most console and cabin layouts. Whether you're upgrading aging sounder hardware or installing a first-generation system, this straightforward, compatible solution delivers the depth and detail that translate to tighter presentations and cleaner separation from bottom clutter.
