Raymarine CPT-DVS Transducer Transom Mount f/Dragonfly 4 & 5
Raymarine CPT-DVS Transducer Transom Mount f/Dragonfly 4 & 5 Product Description
Upgrade your fishing adventures with the Raymarine CPT-DVS transom mount transducer, designed specifically for seamless integration with Dragonfly 4 and 5 series fishfinders. This powerhouse dual-element CHIRP transducer delivers stunning clarity both above and below the waterline, combining an ultra-wide 1.4-degree fan-shaped beam for breathtaking DownVision imagery with a precision conical beam that locks onto fish like a pro. Whether you're chasing bass in shallow weeds or scouting deep-water structures, it senses water depth and temperature to give you the edge on every outing. With a sturdy 6-meter (19.7-foot) cable and easy transom bracket, setup is straightforward for boaters of all experience levels.
Standout Features That Set It Apart
- Dual-Element CHIRP Technology: Experience superior target separation and resolution compared to traditional sonar. CHIRP pulses across a wide frequency range, painting a vivid picture of the underwater world without the guesswork.
- 1.4° Ultra-Wide Fan Beam: Captures expansive DownVision scans, revealing every contour, rock pile, and submerged vegetation in crystal-clear detail—perfect for navigating tricky bottoms.
- Conical Beam for Fish Arcs: The narrow second beam excels at spotting individual fish targets, even in murky water, helping you decide which ones are keepers.
- Depth and Temperature Sensing: Real-time data keeps you informed on conditions, aiding in bait selection and prime fishing spots.
- Robust Build and Cable: Marine-grade construction withstands harsh saltwater exposure, backed by a generous 6m cable for flexible mounting options.
Why Anglers Swear By This Transducer
Imagine gliding over a weed bed and suddenly seeing hidden drop-offs or schools of crappie hugging the structure— that's the magic of the CPT-DVS. Traditional sonar often misses the fine details, but this transducer's DownVision mode acts like an underwater camera, uncovering fish-holding cover that would otherwise stay secret. Boaters report pulling in more fish with less time wasted, thanks to the dual-beam setup that balances wide-area scouting with pinpoint targeting.
For kayak anglers or those with compact vessels, the transom mount shines. It's low-profile, doesn't drag in the water, and pairs perfectly with the portable Dragonfly units. Plus, temperature readings help track thermoclines, where big game fish often lurk during hot summer days or turnover seasons.
Real-World Performance Boosts
- Spot structure in as little as 1 foot of water for shallow-water pros.
- Cut through clutter to ID fish species by size and behavior.
- Stay safe by mapping hazards before your hull does.
Effortless Installation for Quick Results
Mounting the CPT-DVS is a breeze, even if you're new to marine electronics. Clean the transom surface, position the bracket for optimal downward angle (about 20 degrees for most hulls), and secure with included hardware. Route the cable through existing gunwale fittings or along the hull to keep it tidy and protected. Pair it with your Dragonfly in seconds—no complex calibration needed. Pro tip: Adjust the deadrise angle if your boat has a steep transom for the best beam coverage. Most installs take under an hour, getting you back on the water faster.
Compatibility Notes
Tailored for Dragonfly 4DVS and 5DVS models, it plugs right in. For older 5.7-inch or 7-inch Dragonfly units, grab the compatible adapter to bridge the connection effortlessly.
Keep It Performing Like New
Longevity is key on the water. After each trip, rinse with fresh water to flush salt and debris. Inspect the cable for frays and the face for growth— a soft brush and marine cleaner do wonders. Store dry during off-seasons to prevent corrosion. With proper care, this transducer delivers season after season of reliable sonar intel.

Frequently Asked Questions
What makes the CHIRP technology in the CPT-DVS transducer better than standard sonar?
CHIRP sends a continuous sweep of frequencies, providing sharper images, better target separation, and less noise than fixed-frequency sonar. This results in clearer fish arches and structure details across various depths.
Is the CPT-DVS suitable for saltwater use?
Yes, its rugged housing is built to handle corrosive saltwater environments. Regular rinsing extends its life even further.
How deep can the Raymarine CPT-DVS transducer scan?
It performs effectively from shallow waters around 1 foot up to several hundred feet, depending on your Dragonfly model and water conditions.
Does it work with all Dragonfly models?
It's optimized for Dragonfly 4 and 5 series. Older models like the 5.7-inch or 7-inch require a simple adapter cable for compatibility.
Can I install the transom mount myself?
Absolutely—most users complete the install in under an hour with basic tools. The included bracket and instructions make it DIY-friendly.
What if my boat has a high deadrise angle?
The adjustable bracket accommodates various hull shapes. Angle it properly to ensure the beam points straight down for optimal coverage.
Does it measure water temperature accurately?
Yes, the built-in sensor provides precise surface temperature readings, crucial for locating fish in stratified waters.
The CPT-DVS Transducer is a dual element CHIRP transducer that features a 1.4° ultra-wide fan shaped beam for wide DownVision images, as well as a second conical shaped beam for excellent fish targeting. In addition, this device senses the depth and temperature of the water. It is equipped with a 19.7' cable and includes a transom mount bracket.
