CPT-S through-hull transducer mounting kit

The Raymarine R70496 CPT-S transducer mounting kit is designed for installing CHIRP CPT-S transducers on the transom of your vessel. This kit ensures stable mounting and allows precise adjustment of the transducer position, which is critical for optimizing CHIRP cone sonar signal quality.

This kit is specifically designed for transducers in the Raymarine CPT-S range. These transducers are typically fitted to chartplotters such as the Raymarine Dragonfly or multifunction displays (MFD) compatible with LightHouse II software (version 16) from 2016.

To ensure waterproofing during installation, you must use a marine-grade polyurethane sealant with neutral curing. It is critical not to use sealants containing acetate or silicone, as they could potentially damage the plastics of the transducer and mount.

Yes, a mounting template is provided with the kit. It simplifies drilling the mounting holes for the bracket and the adjustment slots, ensuring precise positioning for clear and reliable sonar readings.

After initial assembly, it is recommended to perform a water test. This step allows you to finalize the angle and depth of the sounder by adjusting its position in the adjustment slots. The locking hole should only be drilled and the final screw tightened once the optimal position is found and validated, ensuring optimal performance and eliminating turbulence.

Yes, cutting the depth sounder cable severely degrades the fishfinder's performance and voids the product warranty. Additionally, it invalidates the European CE mark. If the cable is damaged, it must be replaced and cannot be repaired.

No, it is essential to test and use the depth sounder only when it is submerged in water. Using the depth sounder out of the water can cause overheating and damage the device.

CPT-S transducers use CHIRP cone-beam technology. This technology provides target separation and seafloor resolution suited to navigation and inshore fishing.
