Raymarine Transducer Extension Cable - 5m — Product description

Raymarine 5m Extension Cable.

Fits: L755, L760, L770, L1250, DSM 30, 250, 300, CP300, 370.



Extending your transducer cable opens up new possibilities for mounting your sonar sensor exactly where it performs best on your vessel, without compromising signal integrity. The Raymarine 5m transducer extension cable delivers reliable connectivity for L-series fishfinders and DSM systems, letting you position your display unit flexibly while keeping crystal-clear underwater readings. Boaters trust this marine-grade extension for its durability against saltwater spray, constant vibrations, and the relentless demands of open-water adventures.

Seamless Compatibility for Your Setup

This 4-pin extension shines with Raymarine L760 and L1250 series transducers, including models like L755, L760, L770, L1250, and L1260. It pairs perfectly with DSM250/DSM300 fishfinder modules, ensuring no drop in sonar performance. Whether you're upgrading an older L-series chartplotter or fine-tuning a compact setup, this cable maintains the precision echo soundings essential for spotting structure, fish arches, and bottom contours.

  • Supports legacy L-series fishfinders and DSM-compatible networks
  • Removable backshell for quick, tool-free connections
  • 16.5 feet (5 meters) of flexible black cabling to reach awkward mounting spots

Built for the Brutal Marine World

Crafted with rugged thermoplastic insulation and tinned copper conductors, this extension resists corrosion and UV degradation far better than generic alternatives. The overmolded connectors lock out moisture, preventing intermittent signal loss that plagues lesser cables in rough seas. Its slim profile weaves easily through tight bulkheads or along gunwales, preserving a clean deck layout. Anglers and navigators alike appreciate how it extends reach without introducing noise or attenuation—your fishfinder stays responsive from deeper keel mounts to elevated thru-hull positions.

Effortless Installation Steps

Getting this cable online takes minutes, no electrician required:

  1. Power down your fishfinder and disconnect the stock transducer cable at the display or DSM module.
  2. Pop off the removable backshell from both ends of the extension.
  3. Securely plug the transducer end into the extension's female connector, then the male end into your unit.
  4. Reattach backshells, route the cable avoiding sharp edges or heat sources, and secure with ties or clips.
  5. Power up and calibrate—your extended sonar should read flawlessly.

Pro tip: Test continuity with a multimeter before final routing to catch any manufacturing quirks early.

Long-Term Reliability and Peace of Mind

Raymarine's engineering emphasizes longevity, with this cable outlasting stock lengths in high-use scenarios like charter fleets or tournament fishing. It handles temperature swings from icy bilges to sun-baked decks, backed by a reputation for zero-fail connections. Pair it with proper transducer placement—aim for smooth water flow over the face—for optimal bottom tracking and baitfish detection. Skip cheap knockoffs; this genuine extension safeguards your investment in premium marine electronics.

Real-World Applications

Trailered bass boats benefit from easy stowing without cable strain. Offshore cruisers extend to transom mounts amid generators. Kayak anglers route it internally for tangle-free paddling. Wherever your pursuits lead, this 5m lifeline keeps sonar data flowing uninterrupted, enhancing safety through better hazard avoidance and boosting catches with sharper target separation.
