A super-accurate (+/- 1.5%) digital pressure gauge perfect for checking tire pressure on the go, the Digital Check Drive utilizes a tough Composite Matrix construction to survive even the roughest rides in your pack or saddlebag. It's designed around our low-profile Digital Strip Gauge, and its machined aluminum head features a flip-style chuck offering both Presta and Schrader valve compatibility while providing accurate readings up to 350 PSI.
