Magaszkötős, kúpos nyalábsugaras HIGH CHIRP szonda 0/12/20° CPT-S, 6 m kábel

No, it is absolutely not necessary to drill the hull. The CPT-S A80691 transducer is an "in-hull" model, meaning it is installed inside the hull by being glued directly to the fiberglass. This eliminates any risk of leaks and preserves the integrity of your boat.

This transducer is specifically designed to be installed on boats with a solid fiberglass hull (non-sandwich). It will not function properly through wooden hulls, metal hulls (steel, aluminum), or hulls with a foam or balsa core (sandwich construction).

These angles correspond to the different mounting brackets supplied with the transducer to compensate for your hull's V-angle (called "deadrise measurement"). By selecting the bracket suited to your hull's inclination, you ensure the transducer's sonar beam is directed vertically toward the seabed, guaranteeing accurate depth readings and target detection.

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

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

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

Better target separation: It allows easy distinction between fish, even when they are close to the seabed or in tight schools.Less surface noise: It filters interference for a cleaner image.Excellent bottom tracking: It maintains a clear display of the seabed, even at higher speeds.

The transducer comes with an integrated 6-metre cable.

To choose the correct transducer mount, you must measure the deadrise angle of your hull (the angle between the hull sides at the location where you plan to install the transducer). Use a level or an angle gauge to determine the inclination. Then select the mount whose angle is closest to your measurement to ensure optimal performance.

No, the CPT-S A80691 transducer is a conical-beam transducer that provides only traditional CHIRP fishfinder data. 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 proper installation, the manufacturer recommends using a marine-grade neutral-cure polyurethane sealant to secure the depth sounder 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 transducer offers 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 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 the strakes, water intakes, propeller, and any other source of turbulence.Is made of thin solid 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 adhesive transducer is an excellent option for fiberglass sailboats. Its internal installation avoids hull penetration, which is particularly appreciated on sailboats. You just need to 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 cone-beam transducer uses a 25-degree beam angle. This provides a good balance between wide detection coverage and clear bottom definition.

Yes, Raymarine offers specific extension cables for its CPT-S transducers. If the 6 meters provided are not enough to reach your multifunction display, you can purchase a compatible extension cable to increase the range.

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

A glue-on transducer does not directly measure water temperature. If it has a temperature sensor, it will be affected by the hull’s temperature and the air inside the cabin. For an accurate reading of surface water temperature, a through-hull or transom-mounted transducer with an exposed water sensor is required.
