Faria's Kronos series provides your boat's gauge panel with a gorgeous look. Each Kronos gauge has a perimeter-lit spun-aluminum dial with blue and black patterns. The logo is embossed, as are the increments. This boat tachometer's gauges have a polished stainless steel bezel and a domed glass lens (for size four gauge, an 85 mm mounting hole is needed). This tachometer is not only a beautiful addition to the boat's aesthetic, but it's also a crucial component. This boat instrument measures the operating speed of the boat engine, which is important for safety reasons. Another aspect of this tachometer is that it has a brushed finish.
