Like the original, the new Rev/Speed Meter GP is a complete multi function measuring device designed to measure and monitor data such as vehicle speed, engine RPM, and elapsed times. However, the strength of the new unit lies in its differences. Probably the most obvious being its completely redesigned look. This new aesthetically pleasing model was crafted to match the likes of other highly popular A'PEX electronics such as the SAFC and the AVCR (Boost Controller). The new screen utilizes the easy to read VFD (Vacuum Fluorescent Display) with built in light sensor used in many of A'PEX's line up. The new unit also delivers a host of new functions. One of the most exiting of the new features is the option to utilise the revolutionary A'PEX G-Sensor. Note: The G-Sensor is SOLD SEPARATELY.
