The ARB E-Z Deflator (ARB510) is a tire deflator and pressure gauge in one tool. Unscrew the brass chuck onto a Schrader valve, pull the lever to lift the valve core out of the way, and air dumps fast. Thread the core back down and the backlit LCD shows you exactly where you landed. No second gauge, no guessing.
The gauge reads 0-200 psi and is accurate to +/- 1 psi across the 15-75 psi band most rigs air down to. It shows four units — psi, bar, kPa, and KgF — so it works no matter how you think about pressure. The 250mm braided hose has solid brass fittings and a rubber bump guard to take a drop, and the blue backlit display stays readable at dawn or after dark. Max supply pressure is 350 psi.
Power comes from 2x AAA batteries, good for up to about 200 hours of use. The unit ships in a carry pouch that fits a door pocket or a recovery bag. Built for airing down before sand, rock, snow, or washboard, then dialing pressure back up at the trailhead.
