Raymarine IN-HULL Puck F/ST60 Depth

The Raymarine IN-HULL Puck F/ST60 Depth transducer is a proven in-hull depth sounder designed for fiberglass-hulled boats where anglers and boaters need reliable bathymetric data without through-hull drilling. This puck-style transducer mounts flush against the inside of your hull, transmitting sonar signals through the fiberglass to map bottom contours, locate structure, and identify depth changes—critical intelligence for targeting fish and navigating shallow water safely. Built for durability and ease of installation, it integrates seamlessly with Raymarine's established ST60 and ST70 instrument platforms, making it an ideal choice for upgrading existing systems or retrofitting older vessels.

In-hull transducers operate by coupling to the hull material itself, eliminating the risk of water intrusion through a through-hull fitting while avoiding the drag and vulnerability of transom-mount designs. The Raymarine F/ST60 Depth model uses frequency-optimized sonar to cut through fiberglass hulls efficiently, delivering clear depth readings and bottom definition even in challenging freshwater and coastal conditions. Weighing just 3 pounds, the compact puck form factor installs against the inside hull surface—typically on the keel line or centerline—where acoustic coupling is strongest. This design keeps your hull integrity intact and simplifies winterization and maintenance compared to traditional transducers.

The Raymarine IN-HULL Puck F/ST60 Depth is compatible with ST70 Instruments, ST60+ Instruments, and ST290 Instruments, making it a flexible retrofit for legacy and modern Raymarine sounder systems. It works exclusively with fiberglass hulls and should be mounted on a clean, dry surface for optimal acoustic performance. If you're running a fiberglass boat with an aging or failed Raymarine depth sensor, or if you're upgrading to gain better bottom discrimination and fish-marking capability, this transducer delivers the reliability serious anglers and boaters expect from Raymarine's marine electronics heritage.
