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.
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.
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.
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.

Plug-and-play simplicity defines the CPT-S. It connects directly to Element S series for instant CHIRP depth. For broader Axiom family setups:
This flexibility future-proofs your electronics investment, overlaying sonar data on radar, AIS, or charts for a unified boating experience.
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.
It's designed for non-cored fiberglass hulls on sailboats, cruisers, small powerboats, RIBs, and trailer boats. Perfect where transom or thru-hull mounts aren't feasible.
Yes, in-hull mounting provides stable performance at cruising speeds without drag or cavitation issues common to external transducers.
Cut the tube to fit your hull deadrise, apply marine epoxy, insert the transducer, and secure. No hull drilling required—allow 24-48 hours cure time.
It reliably tracks depths up to 600 feet, with excellent resolution for fish ID and bottom discrimination in the High CHIRP band.
Direct connection to select models like Axiom 7 DV; adapters like A80490 enable compatibility with Axiom RV, Pro, and more.
The package contains the in-hull transducer tube, transducer unit, and R-Clip for secure installation.
No, it's optimized for solid, non-cored fiberglass to ensure acoustic coupling without delamination risks.
CPT-S In-Hull CHIRP Transducer
The CPT-S In-hull transducer provides a simple-to-install depth only transducer solution for non-cored fiberglass hulls. Ideal for sailing, cruising, and small powerboat applications, the CPTS-S In-hull transducer supports CHIRP sonar operation centered on 200kHz.
The CPT-S in-hull directly connects to Element S series units.
Will connect to Axiom RV/Axiom Pro RVX and Element HV using the A80490 (Axiom) or A80559 (Element HV) adapters. An innovative transducer tube housing design allows the CPT-S In-Hull to mount in hulls ranging from 0 to 25 degrees deadrise.
