White urethane transom-mount transducer with 10 m cable

Raymarine

Raymarine A80351 CPT-100 DVS CHIRP Transom Mount Transducer

SKU CH-XNHM-MTTPG MPN A80351

A transom-mount CHIRP transducer with DownVision for detailed bottom structure and fish identification down to 600 ft or 900 ft, using 25°/60° beams and a 10 m cable

  • CHIRP DownVision reveals bottom structure up to 600 ft
  • Traditional CHIRP finds fish down to 900 ft
  • Transom mount fits fibreglass, aluminium or steel hulls
  • 25° and 60° beam widths cover wide and narrow views
  • 10 m cable reaches displays without extra extensions

What It Is

The Raymarine A80351 is a transom-mount CHIRP transducer with DownVision capability. Paired with a compatible multifunction display it delivers detailed views of bottom structure, fish and other underwater objects. It suits boat owners who want clear sonar imaging from a transom installation.

Thermals Noise Power

The unit operates passively with no fan or active cooling, so it adds no audible noise to the helm. Power is drawn directly from the connected display through the supplied 10 metre CPT-DVS cable. Urethane housing resists marine growth and impact during normal operation.

Max Depth And Beam

DownVision reaches 600 feet while traditional fish-finding reaches 900 feet. Dual beam widths of 25° and 60° let you choose between focused detail and wider coverage. Buyers needing through-hull mounting or deeper sounding should consider other transducer styles.

Questions about this item

How do I install the transom-mount transducer and which step is commonly done wrong?

Mount the transducer on the transom with the urethane housing facing down, run the 10 m cable to the display, and set the beam angles to 25° and 60°; the step most often missed is aligning the face parallel to the waterline so the 600 ft DownVision and 900 ft fish-finder ranges read correctly.

What maintenance or replacement will the CPT-100 DVS need later?

Inspect the urethane housing each season for marine growth or impact cracks, clean the face with a soft brush, and replace the unit if the depth or temperature readings drift or the 10 m cable jacket shows abrasion.

What limit appears first during sustained use of the CHIRP transducer?

The 600 ft DownVision depth ceiling is reached before the 900 ft fish-finder limit, so prolonged sounding in water deeper than 600 ft loses bottom detail on the DownVision channel first.
