The Fowler/Bowers XTH Holematic Pistol Grip bore gage now has extended travel with fixed anvils. Users no longer have to worry about switching out the anvils like past generations. The pistol grip handle is spring loaded and incorporates a constant measuring pressure to eliminate operator “feel”. The pistol grip style readout essentially takes away all the operator influence when taking measurements. The Fowler/Bowers pistol grip bore gages are accurate and have great repeatability. These bore gages are manufactured in England by Bowers Metrology, one of the most respected bore gaging in the world. Top quality products usually come with a great warranty and the Fowler/Bowers XT Holematic Pistol Grip bore gages are backed with a 5-year warranty. Where else do you see an electronic bore gage with a 5-year warranty?
