A80281 CPT-200 SideVision Transducer

The Raymarine CPT-200 SideVision transducer (A80281) opens up new perspectives for anglers and boaters by providing a panoramic underwater “view” thanks to its side-scanning capability. Unlike traditional fishfinders that only look straight down under the hull, the CPT-200 “peers” far out to the sides – up to 183 m (600 ft) port and starboard – allowing you to spot fish and structure well beyond your boat’s path. When connected to the CP200 sonar module, this transducer employs CHIRP SideVision™ technology – sending a sweep of modulated frequencies that, after processing, return incredibly detailed images on your display. The result is photorealistic sonar imagery: schools of fish, bait pods, submerged timber, or bottom contours all stand out clearly to both sides of your vessel.

A notable feature of the CPT-200 is its adjustable tilt angle. Depending on depth and water conditions, you can choose from three settings: High angle for shallow water, Medium, or Low angle for deeper water scanning. For example, in a shallow river you might use the High angle to cover the nearby area without missing anything, whereas offshore in deep water you’d use Low angle to reach farther under the surface. With the right setting, the SideVision images show incredibly clear depictions of structures like drop-offs, sunken trees, rock formations, and even individual fish or baitfish schools.

The CPT-200 is designed for transom mounting – it attaches securely to your boat’s stern using the included metal bracket. The transducer’s body is built from a durable mix of stainless steel and urethane, ensuring longevity and stability at speed and in waves. The design has been tested for high-speed operation: even at around 25–30 knots, the transducer will continue to hold in the water and send/receive signals (with proper mounting at the right depth). Internally, the CPT-200 contains two independent CHIRP sonar elements – one for the left side and one for the right. These operate simultaneously but on different frequencies to avoid crosstalk, allowing you to see left and right side returns at the same time. The CP200 module processes the signals from both, stitching together a wide 180° underwater panorama beneath your boat.

From a practical standpoint, the CPT-200 greatly enhances fish-finding and situational awareness. Anglers can quickly identify fish schools off to the sides – for instance, spot a baitball 50 m to starboard that would be invisible on a traditional down-looking sonar. They can also discern structure: for example, seeing brush piles, rocky reefs or ledges off to the side that hold fish, enabling them to target those spots precisely. Navigators and explorers of waterways can use SideVision to build a more complete picture of the bottom topography, find submerged wrecks, or gauge the width of channels and shoals, since they’re effectively seeing the underwater terrain around the boat’s course.

In combination with DownVision™: The CPT-200 SideVision works great alongside DownVision transducers (which face downward) – Raymarine anticipates combining SideVision with DownVision for a full 180° view beneath the boat. The CP200 module can network with a CP100 or built-in DownVision sonar on certain MFDs, so the user can see both downward (high-detail “photographic” bottom view) and sideways (wide coverage) sonar images simultaneously. This combination gives anglers or surveyors a comprehensive understanding of the underwater environment around them.

Technical highlights:

• SideVision CHIRP frequency range: in the mid-frequency band (each side operates around ~100 kHz range for an optimal balance of range and resolution).
• Beam width: about 60° per side horizontally (for a total of ~120°–180° coverage). Vertically the beam is thin to concentrate energy horizontally.
• Max effective depth: ~40 m (since side-scan is about range rather than depth; in deeper water the side range may reduce).
• Cable: 9 m length, terminating in a plug that connects directly to the CP200 (no adapter needed).
• Temp sensor: Yes, built-in, so you can monitor water temperature – helpful for finding thermoclines, a key factor in fishing.
• Mount requirements: Suitable for transoms with deadrise from 0° up to 90° – the bracket is adjustable to compensate for hull angle.

By adding the CPT-200 SideVision to your Raymarine system, you gain a strategic advantage – you literally “see” what’s on both sides of your boat. This is especially valuable in structure fishing, where you want to locate fish around underwater cover, or in exploring wrecks and seabed features off to the side. The CPT-200 transducer turns any compatible Raymarine display (aSeries, cSeries, eSeries, Element HV, etc., via the CP200) into a powerful side-scanning sonar, enriching your time on the water with more information and more success in finding what you’re looking for.
