A recent post on mounting an RDS got me thinking about this. I had the non-digital FatWrench for a while, but now I have the Vortex Optic torque driver. They both worked fine, but the Vortex feels more solid… more metal in the construction and the dial seems more precise. The knob is marked 1-10, so you know the exact setting.
I can’t say for sure, but the Vortex appears identical to the Capri Tool and the Gear Wrench torque drivers. I’m thinking that they are probably manufactured by the same parent company.
