The dial uses red graduations, white numerals, and a vivid white pointer staff for strong contrast and quick visibility both day and night, backed by perimeter and thru-dial lighting. The lens is scratch resistant curved glass set in a black, near-flush bezel for a low-profile finish that mounts cleanly into the dash. The dial reads in both U.S. And metric scales with ISO symbols where appropriate, making it suitable for boaters who reference either measurement system. This is part of the Amega line, a black-dial gauge series that has been offered since 1986 and remains a popular choice for boat dash upgrades and replacements. Installation requires a 3.43 inch mounting hole and the unit operates on 12 volts. The kit includes one speedometer gauge as the included component. Because it is sold as a standalone gauge, it can be paired with matching Amega instruments to build out a full dash, or used on its own to replace a failed or outdated speedometer.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
