Analog Dial Gauge:
High quality gauge uses a Steel housing and a rubber shock guard for shop-grade durability. Inside the gauge – a copper coil and a larger diameter mechanism provide the best possible accuracy.
Rapid Response™ Digital Gauge. During inflation, the gauge is capable of showing immediate changes in pressure, enabling fast inflation – now with supreme accuracy. The gauge uses highly accurate, non-wearing circuitry for pressure readings, so it does not wear-out or loose accuracy like traditional Dial gauges. Highly accurate readings are across the whole range, making this tool excellent for Fat Tire, Cyclocross, MTB as well as Road Bikes. Easy Tool-less replacement of the two CR2032 batteries (included).
