No, it is absolutely not necessary to drill a hole in the hull. The CPT-S A80691 transducer is a "hull-mounted" (in-hull) model, meaning it is installed inside the hull by bonding directly to the fiberglass. This eliminates any risk of leaks and preserves your boat's integrity.

This transducer is specifically designed for installation on boats with a solid fiberglass hull (non-sandwich). It will not function correctly through hulls made of wood, metal (steel, aluminum), or hulls with a foam or balsa core (sandwich construction).

These angles correspond to the different mounting brackets provided with the transducer to compensate for the deadrise angle of your hull (known as "relevé de varangue"). By selecting the bracket suited to your hull's inclination, you ensure the sonar beam of the transducer is directed vertically toward the seabed, thus guaranteeing accurate depth readings and target detection.

The CPT-S A80691 sounder is compatible with Raymarine displays featuring a traditional CHIRP sounder channel. This includes:

The Element series (HV, S)The Axiom DV modelsThe Axiom, Axiom+, and Axiom Pro models (on their conical CHIRP sounder channel)

High CHIRP (Compressed High-Intensity Radiated Pulse) technology provides a much clearer and more detailed sonar image than traditional fishfinders. Its main advantages are:

Better target separation: It makes it easy to distinguish fish from one another, even when they are close to the seabed or in dense schools.Less surface noise: It filters out interference for a cleaner image.Excellent bottom tracking: It maintains a clear display of the seabed, even at higher speeds.

The depth sounder comes with an integrated 6-metre cable.

To choose the correct mounting bracket, measure your hull's deadrise angle (the V-shape of the hull) at the location where you plan to install the transducer. Use a level or an angle gauge to determine the inclination. Then select the mounting bracket whose angle is closest to your measurement for optimal performance.

No, the CPT-S A80691 transducer is a conical beam transducer that only provides traditional CHIRP sonar imaging. It is not designed for bottom imaging technologies such as DownVision, SideVision, or RealVision 3D.

The kit includes mounts for 0°, 12° and 20°. For a 15° angle, the 12° mount would be the most suitable. While performance is optimized for exact angles, using the closest mount will yield satisfactory results in most conditions.

For correct installation, the manufacturer recommends using a marine-grade neutral-cure polyurethane sealant to secure the transducer tube to the hull. The tube is then filled with antifreeze (propylene glycol) to eliminate air between the transducer and the hull.

The Raymarine CPT-S High CHIRP sounder provides depth detection performance up to 183 meters (600 feet) in ideal conditions.

No, this transducer is designed exclusively for Raymarine navigation systems and fishfinders. The connector and electronic characteristics are specific to Raymarine products and are not compatible with other brands such as Garmin, Lowrance, or Humminbird.

The main advantage is protection and the absence of drag. Installed inside the hull, the transducer is fully protected from impacts with debris, rocks, or during trailer launching. Additionally, it creates no hydrodynamic drag, which does not affect the boat's speed or fuel consumption performance.

The ideal location is an area of the hull that:

Is always submerged, even when the boat is planing.Is away from frames, through-hulls, the propeller, and any other source of turbulence.Is made of solid, thin fiberglass.Is as close as possible to the boat’s centerline.A good location is often in the bilge, toward the stern of the boat.

Yes, the CPT-S glue-on transducer is an excellent option for fiberglass sailboats. Its internal installation avoids hull penetration, which is particularly appreciated on sailboats. Just ensure it is placed in an area where the hull has no sandwich structure.

No, since the transducer is installed inside the hull, the antifouling paint applied on the outside has no impact on its performance. The sonar signal passes through the hull from the inside to the outside.

The CPT-S conical-beam transducer uses a 25° beam angle. This provides a good balance between wide detection coverage and clear bottom definition.

Yes, Raymarine provides specific extension cables for its CPT-S transducers. If the supplied 6 meters are insufficient to reach your multifunction display, you can purchase a compatible extension cable to increase the range.

The weight of the depth sounder with its cable is approximately 0.615 kg, excluding packaging.

An adhesive-mounted transducer does not measure the water temperature directly. The temperature sensor, if present, will be influenced by the hull’s temperature and the air inside the cabin. For an accurate reading of the water’s surface temperature, a through-hull or transom-mounted transducer with a sensor exposed to the water is required.
