Let’s Talk About Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128
The Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 is a 1kW bronze transducer designed to work seamlessly with Si-Tex CVS-126 and CVS-128 fish finders. It offers dual-frequency operation (50 kHz and 200 kHz) with temperature sensing, making it an ideal choice for serious anglers and boaters venturing into deeper waters.
I needed to upgrade my old, unreliable transducer that was constantly losing signal and giving me inaccurate readings, especially at greater depths. I was specifically looking for a thru-hull model that provided robust performance and accurate temperature readings.
My first impression upon unboxing the Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 was that it was a well-built piece of equipment. The bronze housing felt solid and durable, a reassuring sign for something that will be permanently installed on the hull of my boat.
I considered the Airmar B164 and the Furuno 525T-BSD, but ultimately chose the Si-Tex because it offered a comparable power output and frequency range at a slightly better price point, and was specifically designed for my Si-Tex fish finder. My initial reaction was excitement, combined with a bit of trepidation, knowing the installation process for a thru-hull transducer can be a bit involved.
Real-World Testing: Putting Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 to the Test
First Use Experience
I tested the Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 on a deep-sea fishing trip off the coast of Southern California. The weather was typical for that time of year: sunny with moderate swells.
The transducer performed admirably, maintaining a strong and clear signal even in depths exceeding 600 feet. The temperature readings were also accurate, allowing me to pinpoint areas with temperature breaks that often hold fish. I needed a few minutes to adjust the gain on my fish finder to optimize the clarity of the returns, but the process was straightforward.
Extended Use & Reliability
After several months of consistent use, the Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 continues to deliver reliable performance. I have noticed no signs of degradation in signal quality or accuracy.
The bronze housing shows no signs of corrosion or damage, despite being constantly submerged in saltwater. Cleaning is a breeze; a quick wipe down with a soft cloth after each trip keeps it in top condition. It significantly outperforms my previous transducer, providing a clearer and more reliable picture of the underwater environment.
Breaking Down the Features of Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128
Specifications
The Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 is a bronze, thru-hull transducer operating at 50 kHz and 200 kHz. It has a power output of 1kW, making it suitable for deep water use.
- Manufacturer: Si-Tex
- Hull Type: Thru-Hull
- Frequency: 50 kHz and 200 kHz
- Power: 1kW
- Beam Angle: 14° x 21° @ 50kHz, 3° x 5° @ 200kHz
- Temperature Sensor: Yes
- Speed Sensor: No
The dual frequency allows me to switch between a wider beam (50 kHz) for general search and a narrower beam (200 kHz) for detailed target identification. The 1kW power output is crucial for reaching those greater depths without losing signal strength. The bronze construction ensures durability and resistance to corrosion in the harsh marine environment.
Performance & Functionality
The Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 excels at providing clear and accurate underwater imagery. Its ability to maintain a strong signal at depth is particularly impressive.
The high-frequency (200 kHz) delivers excellent detail, allowing me to distinguish between different types of fish and structure. At the same time, the low-frequency (50 kHz) gives a broader view, essential for searching larger areas. The temperature sensor works flawlessly. The only slight drawback is the absence of a speed sensor, which would have been a nice addition.
Design & Ergonomics
The bronze construction of the Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 is robust and feels very durable. The overall design is simple and functional, focusing on performance rather than aesthetics.
The thru-hull design requires professional installation, but once installed, it’s unobtrusive and doesn’t interfere with the boat’s hydrodynamics. The transducer itself is relatively compact, considering its power output. The installation process can be a bit intimidating if you’re not familiar with marine electronics, so I recommend having it professionally installed.
Durability & Maintenance
Given its bronze construction, the Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 is built to last. Regular cleaning with a soft cloth and mild soap is all that’s needed to keep it in good working order.
I expect it to provide many years of reliable service. Unlike some cheaper transducers, I don’t anticipate any issues with corrosion or premature failure. Its robust design means it will withstand the rigors of regular offshore use.
Accessories and Customization Options
The Si-Tex 707/50/200T-CX Thru-Hull Transducer f/CVS-126 & CVS-128 is specifically designed to work with Si-Tex CVS-126 and CVS-128 fish finders. While there are no specific customization options for the transducer itself, you can adjust the settings on your fish finder to optimize its performance.
The transducer cable is a standard length, but extensions are available if needed. It’s crucial to ensure compatibility with your fish finder before purchasing any accessories. The transducer can also be used with some other fish finders, but consult the manufacturer’s specifications to ensure proper functionality.
