CDI Torque Products 2502MRMH (30-250 inch pounds)
Precision Instruments M2R200H (40-200 inch pounds)
Well I've narrowed it down to two different wrenches. Both are 3/8 drive and they are both high quality Made In USA. Both companies make the torque wrenches for Snap-on. The main difference between the two are the locking mechanisms.
The CDI uses a spring loaded pull down lock ring and the PI uses a locking collar that you twist.
The CDI has laser etched numbers and the PI has engraved numbers.
I'm concerned about the laser etched numbers eventually rubbing off; though I've never owned a tool with laser etched numbers. Those are the only main differences, what do you think?
