AutoMeter Cobalt Digital 3-3/8″ Tachometer & Speedometer Combo
Space-saving dual-function digital instrumentation featuring high-intensity blue LED displays and simple push-button calibration for modern race and custom builds.
Product Overview
The AutoMeter 6987 Cobalt Digital Tachometer & Speedometer Combo unit consolidates two crucial dashboard instruments into a single 3-3/8″ (85.7mm) housing. Utilizing highly accurate digital processing circuits, this gauge eliminates cluster clutter while delivering instantaneous speed and RPM telemetry. Equipped with AutoMeter’s E-Z View Digital LED Display System, the crisp blue readout maximizes legibility under direct sunlight and high-vibration racing conditions while eliminating distracting rapid digit flicker.
Calibration is effortless thanks to the E-Z Cal push-button technology, allowing quick 2-mile road setup without fiddling with DIP switches. The gauge seamlessly interfaces with 1-12 cylinder ignition signals, electronic speed sensors, or AutoMeter’s plug-and-play GPS speed sender.
