Universal Gauge UG-1 Imperial/Metric: Differences and Similarities

Differences:

UG-1 Imperial: 

• The scales on the marking gauge and the depth gauge have both Metric and Imperial graduations 

UG-1 Metric: 

• The scales on both the marking gauge and the depth gauge are in Metric only 

Similarities:

• The Centering Rule on both the UG-1 Imperial and Metric are in Metric only (the centering rule on the UG-1 can be used to quickly find dead center of stock up to 140mm(5.5") in width. The scale is metric which is ideal for a centering rule because all you need to do is align the two same numbers on the right and the left of the stock, and the rule will indicate center at the 0 mark).
