150 mm spring Callipers.
Now we are getting serious. These are superb in a tight situation and very visible comparisons can be made to all concerned. Limited to a maximum distance of 150 mm, extremely accurate and fill the short fall folding umpires measures have at close range. A must for all serious players, but, keep well lubricated to avoid the sudden opening of the callipers. Moving the jack when measuring is embarrassing, firing it on to the next terrain is unforgivable.
