Raymarine Transducer Extension Cable, For CPT-S and DownVision, 4 m

Overview

The Raymarine A80273 is a 4 m transducer extension cable for Raymarine CPT-S, CPT-100, CPT-110, and CPT-120 transducer installations. It adds 13.1 ft of reach when the standard transducer lead comes up short between the transducer and the sonar module or display connection, which is a common issue on boats with a longer cable route from the transom or hull to the helm.

It is used in Raymarine DownVision and related CHIRP transducer setups, including CP100 installations. For a proper sonar install, using the matching extension cable keeps the run in the correct cable family instead of cutting or rejoining the original transducer lead in areas that see moisture and vibration.

Key features

• 4 m (13.1 ft) extension length for transducer runs that need more reach
• Compatible with Raymarine CPT-S, CPT-100, CPT-110, and CPT-120 transducer applications
• Used with Raymarine DownVision and CP100-related installations where the transducer cable will not reach the connection point
• Raymarine recommends using only one extension in the cable run
• Useful for finishing a transducer installation without improvising a splice in the original lead

Compatibility and fit

This is not a universal transducer extension cable. Fit depends on the transducer and connector family already on the boat, so it should be matched to the Raymarine transducer systems listed above. On refits and electronics moves, it is useful when a sonar module or display is mounted farther forward than the original cable route allowed.

Installation and setup

Plan the full cable path before pulling it through rigging tubes or bulkheads so the added 4 m solves the shortfall where you need it. Keep the run as short as practical, avoid sharp bends, and place connection points where they stay protected from standing water and routine washdowns.

This cable is a good match for boat owners finishing a clean Raymarine sonar install without changing the transducer itself. It suits smaller boats that need a little extra distance to the helm and larger layouts where the route includes service loops or a longer run through the hull and console.
