Raymarine CPT-100 DVS Transom Mount CHIRP Transducer — Product description

CPT-100DVS Transom Mount Chirp Transducer, Depth & Temperature, Direct connect to CP100 & xx8 MFDs (10m cable)

Unlock Crystal-Clear Underwater Insights with Advanced CHIRP Technology

Imagine gliding across the water, effortlessly spotting fish schools amid detailed bottom contours and structures that traditional sonar might miss. The Raymarine CPT-100 DVS transom mount transducer delivers this reality by blending high-frequency CHIRP DownVision imaging with robust fishfinding capabilities. Mounted securely on your boat's transom, this urethane-housed unit pierces depths up to 600 feet for DownVision and 900 feet for standard sonar, revealing submerged worlds with unmatched clarity.

Crafted for real-world boating demands, it thrives on hulls made of fiberglass, wood, or metal, adapting to transom deadrises from 0 to 90 degrees. Its 33-foot cable offers flexible routing, while built-in depth and temperature sensors keep you informed without extra gear.

Standout Features That Elevate Your On-Water Experience

  • Dual-Beam Precision: A narrow 25-degree conical beam excels at pinpointing fish, while the wide 60-degree DownVision sweep maps lakebeds, reefs, and wrecks in photorealistic detail.
  • Versatile Frequencies: Operates at 350 kHz for DownVision side-by-side imaging and 200 kHz CHIRP for conventional fish arches, ensuring versatility across calm bays or choppy offshore runs.
  • Rugged Build: Urethane construction resists impacts, corrosion, and marine growth, promising seasons of reliable performance even in harsh saltwater environments.
  • Smart Sensors: Continuously logs water depth and temperature data, helping you track thermoclines where fish congregate.

How CHIRP DownVision Transforms Sonar Imaging

Unlike single-frequency sonars that deliver flat, abstract readings, CHIRP DownVision pulses across a spectrum of frequencies for sharper, more defined returns. The result? Bottom-hugging images that distinguish rocks from weeds, submerged timber from sandy flats, and baitfish from predators. Pair it with a compatible sonar module, and you'll navigate shallow drafts or scout deep drop-offs with confidence, turning guesswork into targeted outings.

Anglers rave about its ability to reveal structure-oriented species like walleye hugging breaklines or bass ambushing near docks—details that can mean the difference between a skunked trip and a limit haul.

Effortless Transom Mounting for Quick Setup

Installing this transducer is straightforward for DIY boaters. Position it 1/3 from the transom's center, ensuring the hull's running angle keeps it submerged at speed. Use marine-grade stainless hardware to secure it, then route the cable away from interference sources like engines or bilge pumps. Adjustable for deadrises up to 90 degrees, it maintains optimal water flow on planing hulls, minimizing air bubbles that blur readings.

Pro tip: Clean the transom thoroughly and apply a thin layer of marine sealant for a watertight bond. Test at various speeds post-install to fine-tune performance.

Why Boaters Choose This Transducer for Superior Results

Beyond specs, it's about enhancing every trip. Fish smarter by identifying holding spots instantly, avoid no-fish zones with precise bottom mapping, and monitor environmental shifts via temperature logs. Its wide compatibility with sonar systems means seamless integration into your existing setup, without the hassle of multiple units.

Durability shines in longevity—urethane sheds growth better than plastic alternatives, reducing drag and maintenance. Whether chasing trophy stripers or mapping new fishing grounds, this tool empowers informed decisions that boost success rates.

Keep It Performing Like New with Simple Care

Rinse with fresh water after saltwater exposure to fend off salt buildup. Inspect the face for nicks or fouling quarterly, gently scrubbing with a soft brush and non-abrasive cleaner. Store dry during off-seasons to prevent moisture ingress. These habits extend its life, ensuring consistent high-res signals year after year.

Frequently Asked Questions

What makes the CPT-100 DVS different from standard transducers?

It combines CHIRP DownVision for detailed bottom imaging with traditional fishfinding sonar, offering both photo-like views and fish-targeting arches in one compact unit.

Can this transducer handle high-speed boating?

Yes, its transom-mount design and hydrodynamic shape keep it in clean water flow across planing speeds, with adjustments for deadrises up to 90 degrees.

What hull types is it suitable for?

It's approved for fiberglass, wood, and metal hulls, making it versatile for most recreational and light commercial boats.

Does it measure water temperature?

Absolutely, the integrated sensor records temperature alongside depth, aiding in locating thermal edges where fish activity peaks.

How deep can it scan effectively?

DownVision reaches 600 feet for imaging, while fishfinder mode extends to 900 feet, covering inland lakes to coastal waters.

Is professional installation required?

No, most users install it themselves with basic tools, following transom guidelines for optimal beam projection.
