Let’s Dive into Sierra International 70002D Speedometer Matrix
The Sierra International 70002D Speedometer Matrix isn’t just another gauge; it’s a smart, CANbus-driven instrument promising a comprehensive data display for your boat or vehicle. Manufactured by Sierra International, this speedometer aims to provide real-time information and crucial alarm notifications through its LCD screen. Its rugged build and advanced features caught my eye, promising enhanced situational awareness.
I was struggling with older, analog gauges in my fishing boat that were becoming increasingly unreliable. They offered limited information, making it difficult to quickly assess the vessel’s performance. I needed a modern, digital solution capable of displaying multiple data points simultaneously and providing alerts for potential issues, ultimately leading me to research the Sierra International 70002D Speedometer Matrix.
Upon unboxing, the gauge feels solid and well-constructed. The IP67 waterproof rating and nitrogen-filled housing inspired confidence, suggesting it could withstand harsh marine environments. Its 3-inch size struck a good balance between visibility and conserving valuable dashboard space.
I considered similar products from Garmin and Lowrance, both known for their marine electronics. However, the Sierra International model offered a dedicated speedometer function with integrated alarm features at a more attractive price point. The Garmin and Lowrance units I looked at were combination GPS/chartplotter/gauge systems, which added cost and complexity I didn’t need.
Initially, I was excited to install the Sierra International 70002D Speedometer Matrix. The promise of a clear, digital display and built-in alarms piqued my interest, hoping it would finally modernize my boat’s instrumentation. Time would tell if it lived up to the hype, but my initial impressions were positive.
Real-World Testing: Putting Sierra International 70002D Speedometer Matrix to the Test
First Use Experience
I installed the Sierra International 70002D Speedometer Matrix on my 21-foot center console fishing boat. The initial test run took place on a choppy bay during a typical afternoon fishing trip. The gauge was connected to the boat’s existing NMEA 2000 network.
Despite the spray and occasional splash, the display remained clear and readable. The bright LED backlighting was a welcome addition, especially during dusk. Navigating through the different data displays was intuitive, although the initial setup required some reading of the manual.
There were no immediate issues, but I did notice that the speedometer reading seemed slightly higher than my GPS-based speed. A calibration adjustment might be necessary. The alarm functions weren’t triggered during this initial run, but I was eager to test them in more demanding scenarios.
Extended Use & Reliability
After several weeks of regular use, the Sierra International 70002D Speedometer Matrix has proven to be a reliable addition to my boat’s instrumentation. It has endured multiple fishing trips in varying weather conditions, from calm seas to moderate swells. The gauge has held up well against sun exposure and saltwater spray.
There are no visible signs of wear or tear. The waterproof housing has performed flawlessly, preventing any moisture intrusion. Cleaning the gauge face is simple, usually just requiring a quick wipe with a damp cloth.
Compared to my previous analog speedometer, the Sierra International 70002D Speedometer Matrix is a significant upgrade. The digital display is far more precise and offers a wider range of data. The alarm functions provide an added layer of safety and peace of mind. I’m confident this gauge will continue to perform reliably for years to come.
