Let’s Talk About Raymarine CPT-S Thru-Hull
The Raymarine CPT-S Thru-Hull transducer is a specialized piece of marine technology designed for serious anglers and boaters. Manufactured by Raymarine, a leader in marine electronics, this thru-hull transducer offers high chirp sonar capabilities. It promises to deliver detailed underwater imagery without the downvision element.
My search for the perfect fish finder led me here. My aging boat’s existing sonar was outdated, and I needed a reliable, high-performance solution. I wanted something that could clearly identify fish and structure.
Unboxing the CPT-S Thru-Hull was a straightforward affair. The transducer felt solid and well-made, which is reassuring for something that will be permanently mounted on my boat. Its plastic housing seemed durable, ready to withstand the harsh marine environment.
I considered the Airmar B175HW and the Raymarine RV-220 thru-hull transducers. I ultimately chose the CPT-S Thru-Hull due to its dedicated high chirp performance at a more accessible price point. The CPT-S Thru-Hull appeared to offer the best balance of capability and cost for my needs.
My initial impression was cautiously optimistic. The promise of high chirp without downvision was intriguing. I hoped it would cut through the clutter and provide a clear, focused view of what’s below.
Real-World Testing: Putting Raymarine CPT-S Thru-Hull to the Test
First Use Experience
I first tested the Raymarine CPT-S Thru-Hull in the Puget Sound, known for its strong currents and diverse marine life. The installation process was a bit involved. I needed to carefully measure and cut the hole in my boat’s hull.
Performance in the choppy waters was impressive. The high chirp sonar provided a clear and detailed image of the bottom. The transducer easily distinguished between rocks, seaweed, and fish.
The CPT-S Thru-Hull was relatively easy to use. It seamlessly integrated with my Raymarine Axiom MFD, and the sonar readings were intuitive. I did need to adjust the gain settings initially to optimize the image clarity.
The most surprising thing was the clarity of the fish arches, even at higher boat speeds. My old transducer struggled to maintain a clear picture above 5 knots. The Raymarine CPT-S Thru-Hull maintained excellent target separation at much higher speeds.
Extended Use & Reliability
After several months of consistent use, the Raymarine CPT-S Thru-Hull has proven to be a reliable piece of equipment. The transducer has shown no signs of wear and tear, despite being exposed to saltwater and occasional bumps. Its plastic housing has held up well.
Maintenance has been minimal. I periodically clean the transducer face with a soft brush to remove any marine growth. This simple routine has kept it functioning optimally.
Compared to my previous sonar system, the CPT-S Thru-Hull is a significant upgrade. It provides far greater detail and accuracy, especially in deeper water. The clarity of the images allows me to identify smaller fish and subtle changes in bottom structure.
Breaking Down the Features of Raymarine CPT-S Thru-Hull
Specifications
The Raymarine CPT-S Thru-Hull is a high chirp sonar transducer. It does not include downvision. It connects to Raymarine CP100 sonar modules and MFD series that end in axx8 or esxx8.
It is a thru-hull mounted transducer. It has a plastic housing. This helps prevent galvanic corrosion with metal hulls.
These specifications translate to clear, high-resolution sonar imagery. This is specifically beneficial for identifying fish and bottom structure. The thru-hull mounting provides optimal signal transmission.
Performance & Functionality
The Raymarine CPT-S Thru-Hull excels at providing detailed sonar images. It reliably identifies fish, structure, and changes in bottom composition. Its performance is particularly impressive in deeper water.
Its strength lies in its focused high chirp performance. A weakness might be the lack of downvision for users desiring both technologies. It meets and exceeds my expectations for a dedicated high chirp transducer.
Design & Ergonomics
The CPT-S Thru-Hull boasts a robust build quality. Its plastic housing feels durable and well-sealed. The transducer is relatively compact, minimizing drag.
Installation requires cutting a hole in the hull, so professional installation is recommended. After installation, it is easy to use via the compatible Raymarine MFD. The Raymarine MFD’s interface is user-friendly, making it easy to interpret sonar data.
Durability & Maintenance
The plastic housing is designed to withstand the harsh marine environment. Regular cleaning with a soft brush is recommended. With proper care, it should last for many years.
Accessories and Customization Options
The Raymarine CPT-S Thru-Hull comes with the necessary hardware for installation. There are no specific customization options for the transducer itself. However, its performance can be enhanced through proper gain settings.
It is compatible with Raymarine MFDs, offering integration with GPS, chartplotting, and other navigation features. Users can also fine-tune sonar settings to optimize performance based on water conditions.
Pros and Cons of Raymarine CPT-S Thru-Hull
Pros
- Exceptional high chirp sonar clarity provides detailed underwater imagery.
- Thru-hull mounting ensures optimal signal transmission.
- Durable plastic housing withstands the marine environment.
- Easy integration with Raymarine MFDs.
