It runs off a traditional analog sender or straight off a J1939 CAN network, each gauge carrying its own microprocessor and RGB backlighting. If you're building or refreshing a helm and want a gauge that plays both old-school and modern, this is it.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eVDO has been building marine gauges for over 50 years, and the SingleViu line is where that experience meets modern engine electronics. This is the 100mm (4\") tachometer with a 0 to 3000 RPM scale, sized for slower-turning diesels and any engine that lives in that range. It drops into the standard 4-inch panel hole most helms already have cut, so on a lot of boats this is a straight swap for a tired old tach.\u003c\/p\u003e\n\u003cp\u003eHere's what makes the SingleViu different from a plain analog gauge. Each one carries its own microprocessor. That gives it dual-input capability. Out of the box it reads a traditional analog sender through its 0 to 400kHz input, so it works with the senders you already have. But flip it over to J1939 CAN through the SingleViu Configuration software and it'll talk straight to a modern engine's data network. Same gauge, two worlds. If you're running an older mechanical setup today and repowering down the road, the tach comes with you instead of ending up in a parts drawer.\u003c\/p\u003e\n\u003cp\u003eOn a CAN network it does more than spin the needle. The SingleViu can display J1939 system fault codes right on its LCD, so a check-engine condition shows up at the helm instead of hiding in a diagnostic port. For a lot of boaters that's the feature that sells it.\u003c\/p\u003e\n\u003cp\u003eThe build is what you'd expect from VDO. Waterproof and fog-proof construction, water resistant front and rear, so a wet dash or a splashy day doesn't fog the lens or kill the gauge. The movement is an advanced stepper motor, which means the needle is quick and steady instead of the lazy sweep you get from old bimetal tachs. Backlighting is RGB LED, set to white by default, and you can change the color to match the rest of your panel if you're running other SingleViu gauges.\u003c\/p\u003e\n\u003cp\u003eWiring is straightforward. The gauge uses Molex MX150 connectors (8-pin and 12-pin) and ships with the wire harness in the box, so you're not hunting for a pigtail. It runs on 12 to 24 volt systems, which covers just about every boat out there. Mounting is handled by VDO's Spin-Lok hardware, a clamp system that snugs the gauge into the panel from behind without a lot of fuss. No stud kits to line up, no fighting the gauge from the front. You cut the hole, drop it in, and clamp it down.\u003c\/p\u003e\n\u003cp\u003eA couple of honest install notes. Behind the dash you'll want to leave clearance for the gauge body and the harness, so measure your rear depth before you commit. And if you're feeding it from an analog sender, take a minute to ground the signal wire shield at the gauge end. That knocks down the RF noise alternators like to throw, which is the usual reason a tach reads jumpy at idle. On a magnetic pickup, setting the gap correctly matters too. Small stuff, but it's the difference between a rock-steady needle and one that dances.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone refreshing a helm who wants a gauge that looks sharp, reads accurately, and won't box them in later. The 3000 RPM scale is the one you want for slower diesels and displacement power. If you're running a high-revving gas engine, VDO makes a higher-scale SingleViu tach that suits that better, so match the scale to your engine. Get the range right and this gauge will read true for years.\u003c\/p\u003e\n\u003cp\u003eIt's sold as an individual gauge, so if you're building a full panel you can add matching SingleViu instruments to keep the whole dash consistent, same face, same lighting, same look. That's the nice part about a system line. Start with the tach, fill in the rest as the budget allows. Order what you need and we'll get it moving.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e0 to 3000 RPM scale on a 100mm (4-inch) face, sized for slower-turning diesels and displacement engines\u003c\/li\u003e\n  \u003cli\u003eDual input: reads a traditional analog sender (0 to 400kHz) or switches to J1939 CAN via the SingleViu Configuration software\u003c\/li\u003e\n  \u003cli\u003eOnboard microprocessor displays J1939 system fault codes right at the helm\u003c\/li\u003e\n  \u003cli\u003eRGB LED illumination, set to white by default and adjustable to match your panel\u003c\/li\u003e\n  \u003cli\u003eWaterproof and fog-proof construction, water resistant front and rear\u003c\/li\u003e\n  \u003cli\u003eAdvanced stepper-motor movement for a quick, steady needle\u003c\/li\u003e\n  \u003cli\u003eRuns on 12 to 24 volt systems, covering nearly every boat's electrical setup\u003c\/li\u003e\n  \u003cli\u003eMolex MX150 connectors (8-pin and 12-pin) with the wire harness included in the box\u003c\/li\u003e\n  \u003cli\u003eSpin-Lok mounting hardware clamps the gauge in from behind for a clean install\u003c\/li\u003e\n  \u003cli\u003eFits the standard 4-inch panel cutout for a straight swap on most helms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized VDO reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size hole does this tachometer need?\u003c\/summary\u003e\n    \u003cp\u003eIt fits the standard 100mm (4-inch) panel cutout that most helms already have.
