Chapter 1: Important information Caution: Do not cut transducer cables Certified Installation • Cutting the transducer cable severely reduces sonar performance. If the cable is cut, it must be replaced, it cannot be repaired. Raymarine recommends certified installation by a Raymarine approved installer. A certified installation qualifies for enhanced product warranty benefits. Contact your Raymarine dealer for further details, and refer to the separate warranty document packed with your product.
Disclaimer Raymarine does not warrant that this product is error-free or that it is compatible with products manufactured by any person or entity other than Raymarine. check the Raymarine website (www.raymarine.com) to ensure you have the most up-to-date version(s) of the documentation for your product.
Chapter 2: Document and product information Chapter contents • • • 2.1 Document information on page 10 2.2 CHIRP Sonar overview on page 11 2.
2.1 Document information This document contains important information related to the installation of your Raymarine product. • CPT-70 and CPT-110 — plastic transducers are recommended for fiberglass and metal hulls and should not be used on a wooden hull.
2.2 CHIRP Sonar overview 2.3 CHIRP DownVisionTM overview CHIRP sonar produces a conical shaped beam, the coverage of the conical beam is the water column directly beneath the vessel DownVisionTM produces a wide–angle side-to-side beam and a thin fore-to-aft beam. The coverage of the DownVisionTM beam is a water column directly beneath and to the sides of the vessel. Conical beam DownVisionTM beam D12777-2 D12784-2 Sonar is effective at a range of speeds.

Chapter 5: Pre-installation test Chapter contents • 5.
5.1 Testing the transducer Transducer operation should be checked before installation. 1. Connect the transducer to the sonar module’s / display’s transducer connection. 2. Fully submerge the transducer in water. 3. Power up the sonar module / display. 4. Open a Fishfinder application on your display. 5. Check that accurate depth and temperature readings are displayed. 6. If you experience difficulties obtaining readings then contact Raymarine Technical Support.
Chapter 6: Mounting — CPT-70 / CPT-110 Chapter contents • • • • 6.1 Dead rise angle on page 26 6.2 Mounting the transducer in a hull with a dead rise on page 28 6.3 Mounting the transducer in a hull without a dead rise on page 29 6.
6.1 Dead rise angle 1 2 3 The dead rise angle is the angle of the vessels hull from the centerline. The transducer can be installed on vessel with a dead rise angle of 0° to 25°. The transducer should not be installed on a vessel with a dead rise angle of greater than 25°.
Retain the top half of the block as this will provide a level surface inside the hull to tighten the nut against. 7. Check the bottom half of the block against the hull to ensure a good fit. Ensure that the block runs parallel to the centerline of the vessel. 8. If there are gaps between the block and hull then use an appropriate file to shape the block until a precision fit is achieved. Dead rise angle Fence to blade distance 19° 9.0 mm 20° 8.4 mm 21° 7.9 mm 22° 7.3 mm 23° 6.8 mm 24° 6.
6.2 Mounting the transducer in a hull with a dead rise When mounting the transducer in a hull that has a dead rise angle the transducer should be mounted following the steps below. Important: Do NOT remove the label attached to the transducer cable as it contains important information.
6.3 Mounting the transducer in a hull without a dead rise When mounting the transducer in a hull with a flat bottom (no dead rise) follow the steps below. Important: Do NOT remove the label attached to the transducer cable as it contains important information.
12. Apply a thick bead of marine grade sealant to the bottom of the nut. 13. Ensuring that the dead rise block and transducer do not move, secure the transducer assembly by tightening the nut. 14. Hand tighten the nut and add a further quarter turn using an adjustable wrench (spanner). In order to prevent leaks and transducer movement when hit by objects or waves, ensure that the nut is adequately tightened. You should see the sealant protruding from the edges of the applied surfaces. 6.

7.3 Cored fiberglass hull mounting If installing in a cored fiberglass hull, it is recommended that the transducer is mounted in a non-cored section. D13356-1 Caution: Transducer cable • Do NOT cut, shorten, or splice the transducer cable. • Do NOT remove the connector. If installation in a cored section of the hull is required then the area around the hole must be adequately strengthened to ensure it is not damaged when tightening the transducer.
