AVAILABILITY : 2Giustaforza Professional has three main differences that make it stand apart from the standard Giustaforza:- A RED ANODIZED BODY:to easily find the torque-wrench when working on a crowded tool table;- A more PRACTICAL BOX:although not as compact as the one of standard Giustaforza, the box of Giustaforza Professional is even stronger, allowing to easily pick the desired bit and put each bit at its place, hence being more practical for professional mechanics or for those who use the wrench often;- A SPECIAL RATE FOR RE-CALIBRATION:owners of GF Professional have right to a free first re-calibration (recommended after 5.000 ''clicks' of the wrench, more details here), which is then 0? plus shipping instead of 35? plus shipping (conditions may vary according to the country where you bought your wrench);The other characteristics remain the same as for the black standard Giustaforza.
