Tire Pressure Gauges - Analog Vs. Digital   
      
   The purpose of my inquiry, after two months of experience with two digital   
   tire gauges, is not to find   
   out which brands of gauge are better than others, but rather, to find out   
   which type(dial face vs digital)   
   you feel:   
      
   1. Consistently gives the same result over and over again.   
   2. Has the best absolute accuracy(against a known reference gauge)   
      
   One of my two digital models, a DIYCO Pro, takes 3-5sec. to reach a reading.     
   After dumping it(releasing   
   the air from it when it is removed from a tire), and valving that same tire   
   again two or three more times,   
   I get different readings as much as 2psi apart.  IE: first read: 33.5psi,   
   second read, 32.9, third read, 33.2,   
   etc.   
      
   If I set all my car's tires to exactly 33.0psi, how do I know all four are   
   really exactly 33.0psi(according to a   
   theoretical reference gauge)?   
      
   With dials, If I keep taking readings, the indicated pressure goes down just a   
   hair with each successive   
   reading, but, I get a reading right away, and bleeding down is fast and no   
   nonsense compared to the digitals,   
   which "slowly climb back"from a bleed:  32.8...32.9.........? .....33.0! Whew,   
   finally!   
      
   Which do you prefer: Decimal precision of a digital tire gauge that you must   
   wait a few seconds for, or, no-   
   nonsense, quick reading of an analog?  And is either really any better?
