Raymarine Active Depth/Temperature Thru Hull Transducer

Enhance your boating experience with the Raymarine Active Depth/Temperature Thru-Hull Transducer, a retractable sensor designed for precision in challenging marine environments. This innovative device integrates seamlessly into your vessel's hull, delivering real-time depth and water temperature data essential for safe navigation, fishing, and leisurely cruises. Its high-frequency operation ensures sharp, reliable readings even in shallow waters, making it a favorite among sailors, powerboaters, and offshore adventurers who demand accuracy without compromising on durability.

Superior Design for Real-World Boating Demands

Crafted with marine-grade materials, this thru-hull transducer features a compact 2-inch (51mm) diameter body that fits most hulls up to 2.125 inches (55mm) thick. The retractable piston mechanism allows you to easily pull it back for cleaning marine growth or when beaching your boat, preventing damage from debris or grounding. A right-angle cable exit keeps wiring tidy and protected, reducing snag risks during installation or maintenance.

Effortless Integration with Modern Systems

Pair it directly with wireless NMEA interfaces for plug-and-play connectivity in setups where GPS provides boat speed data. This eliminates the need for complex paddlewheel sensors, streamlining your electronics suite. Whether you're upgrading an older chartplotter or building a networked helm, its straightforward connection minimizes downtime and maximizes on-water performance.

High-Frequency Precision for Shallow and Varied Waters

Operating at 235kHz, the transducer excels in high-resolution depth sounding, ideal for rivers, bays, and coastal areas where traditional lower frequencies fall short. The built-in active electronics amplify signals for cleaner data, filtering out noise from boat wakes or choppy conditions. Coupled with accurate temperature sensing, it helps you monitor water columns for baitfish layers or thermal breaks during trolling sessions.

Installation Tips from Seasoned Boaters

Selecting the right thru-hull location is key—position it forward of the propeller and away from strakes for optimal beam spread. Use a fairing block on stepped hulls to align the face perpendicular to the waterline, boosting accuracy at speed. The removable design means routine biofouling checks are hassle-free; simply retract, wipe down, and redeploy. Always bed the unit with marine sealant to ensure a watertight seal against corrosion.

Maintenance and Longevity in Harsh Conditions

Regular freshwater rinses after saltwater exposure keep the piston smooth and readings crisp. In warm climates, inspect the O-rings annually for wear. This transducer's rugged construction withstands the rigors of trailering, winter storage, and heavy use, often outlasting competitors in real-world tests by avid cruisers.

Ideal for Diverse Vessels and Activities

Perfect for sailboats needing a low-profile sensor below the waterline, center-console fishing rigs chasing structure, or yachts prioritizing wireless data sharing across multifunction displays. Anglers appreciate the temperature insights for luring species like snapper or walleye, while navigators rely on its depth alerts to avoid shallows during low tides.
