In a tin torpedo tube like a fancy cigar, you've been spoilt with the deluxe model ;-) Mine lives in the spare pocket of the little pouch that the tread depth gauge came in, seems to be made for it. Kept handy if I need a second opinion on the kick of the tyre ping test. Definitely not of a calibrated standard but seems to agree ±1 psi with the pressure gauges on on the mini compressors supplied in lieu of a spare wheel by Vauxhall and Ford.
