Raymarine CPT-100 DVS Transom Mount CHIRP Transducer

The Raymarine CPT-100 DVS Transom Mount CHIRP Transducer is purpose-built for anglers and boaters who demand high-resolution sonar imaging at depths where traditional fishfinders fall short. Designed for transom mounting on vessels of all sizes, this transducer combines DownVision and conventional CHIRP fishfinding in a single, durable housing—eliminating the need for dual transducers and simplifying installation. Whether you're targeting structure in 600 feet of water or scanning shallow flats, this all-in-one solution delivers the situational awareness serious anglers depend on.

Built from marine-grade urethane, the CPT-100 DVS withstands prolonged saltwater exposure and UV degradation while maintaining acoustic integrity season after season. The transducer operates across a CHIRP DownVision frequency band with a dual beam width configuration—25 degrees on the high-frequency channel for narrow, focused imaging and 60 degrees on the low-frequency channel for wider coverage. This beam geometry allows you to scan both tight bottom structure and expansive water columns, while the 600-foot DownVision maximum and 900-foot conventional fishfinder capability ensure reliable performance from shallow bays to continental shelf edges. Temperature recording capability adds another diagnostic layer for understanding fish behavior and seasonal patterns.

Transom mounting makes installation straightforward on most recreational fishing boats, center consoles, and recreational cruisers without requiring through-hull drilling or hull modifications. The CPT-100 DVS integrates seamlessly with Raymarine's ecosystem of chartplotters and sonar systems, providing intuitive display options and data logging for trip review and mapping. This transducer suits tournament anglers, professional guides, and weekend boaters alike—anyone who relies on real-time bathymetric detail and fish-finding accuracy. Compact dimensions (6 x 5 x 9 inches) and moderate weight (1.6 lbs) mean minimal drag and easy repositioning, making it ideal for fast fishing boats where aerodynamics and weight distribution matter.
