xtach mk v 



The tachometer is the most important instrument in a modern race car; yet finding a small, reliable, and accurate instrument useable in racing conditions is a challenge. The xtach was developed to meet and exceed all these requirements. After overwhelming demand, the xtach is available in a compact, CNC machined billet aluminum enclosure with a laser cut frontplate. Large 12mm buttons are easier to actuate while wearing racing gloves. Every instrument is assembled and programmed to your specification and can ship pre-programmed.
