The dad who lets his tyres down with the tip of a pocket knife
What it is
The ARB deflator with a 10 to 60 psi gauge and a recovery gear pouch. Removes the valve core to drop pressure quickly and reads while it goes.
Why we picked it
Small, brilliant, and instantly recognised by anyone who drives on sand. Letting tyres down properly is the first thing a 4WD course teaches and the thing most people do badly with a key and a guess, which this replaces entirely.
