Raymarine CPT-S In-Hull CHIRP Transducer

Discover the effortless way to add precise depth tracking to your vessel with the Raymarine CPT-S In-Hull CHIRP Transducer. Perfect for boaters who prioritize clean installations without compromising on sonar performance, this transducer slips seamlessly into non-cored fiberglass hulls, delivering crystal-clear readings even at speed. Whether you're navigating tricky shallows during a coastal cruise or scouting prime fishing spots on a weekend sail, its High CHIRP technology at 170-230 kHz cuts through the noise for superior target separation and bottom detail.

Why Choose an In-Hull CHIRP Transducer for Your Boat?

Unlike transom-mounted options that drag in the water or thru-hull installs requiring hull penetration, the CPT-S mounts inside the hull using a simple glue-in method. This setup minimizes drag, protects the sensor from impacts, and suits boats like RIBs, trailerable craft, and performance sailboats where every ounce counts. The innovative adjustable tube housing conforms to deadrise angles from 0° to 25°, ensuring optimal beam alignment for reliable data—no air pockets or distortion from hull flex.

Boaters rave about its ability to maintain lock-on during planing or heeling, providing consistent depth up to 600 feet with a wide 25° cone angle. High CHIRP pulses reveal fish arches, bait schools, and soft-hard bottom transitions that traditional fixed-frequency sonar often misses, making it a game-changer for casual anglers and navigators alike.

Effortless Installation and Hull Versatility

Setting up the CPT-S is straightforward for DIY enthusiasts. Cut the included transducer tube to match your hull's contour, bed it in epoxy, and secure the unit. No fairing blocks or complex brackets needed. It's tailored for solid fiberglass hulls without coring, common on many production sailboats and day cruisers. Pro tip: Sand the hull interior smooth and use a slow-cure adhesive for a bubble-free bond that withstands vibration and temperature swings.

• Compatible deadrise: 0°, 12°, 20° (adaptable up to 25°)
• Ideal for vessels avoiding external mounts
• 6-meter cable reaches most helm stations

Once installed, pair it with your Raymarine multifunction display for real-time overlays on charts, enhancing safety when anchoring in unfamiliar bays or threading coral heads.

Seamless Integration with Raymarine Displays

Plug-and-play simplicity defines the CPT-S. It connects directly to Element S series for instant CHIRP depth. For broader Axiom family setups:

• Axiom 7 DV: Direct
• Axiom RV, Axiom+ RV, Axiom Pro RVX, RVX1000: Use A80490 adapter
• Element HV: Use A80559 adapter
• Legacy: aSeries, eS Series DownVision, CP100

This flexibility future-proofs your electronics investment, overlaying sonar data on radar, AIS, or charts for a unified boating experience.

Real-World Applications and Tips

Sailors use it to monitor keel clearance in tidal races; powerboaters track contours for trolling paths. Maintain peak performance by wiping the hull interior annually and checking cable connections seasonally. In variable conditions, tweak CHIRP range on your MFD for zoomed-in bottom structure—ideal for spotting wrecks or drop-offs.
