I had the chance to handle one of these at IMTS 2014 on Tues. It is still my favorite calculator. I am currently using the machinist calc pro and I can't wait to get a pro2.

This Calculator is extremely useful and user friendly. I purchased a total of 8 for our Toolmakers and most have had the trade for 25 + years and are impressed and continually use the calculators.

I have found the Machinist Calc Pro to be an ideal calculator for the machinist on the shop floor. In a matter of seconds I can easily do everything from calculate speeds and feeds data and determine tap drill sizes, to working trig problems. And jumping between inch and metric is a breeze. It is also ideal for CNC programming, so I encourage everyone that I train to add this calculator to their tool box in order to save time and be more productive.

 
Superb Product

As someone who develops software for a living and has written Machinist Calculator Applications for mobile devices, this unit is simply awesome.

I have been a Journeyman Tool and Die Maker for 10yrs. This calculator has most of the calculations you need on a daily basis. Now I don't have to look up charts or do trig. formulas. I wish I had this 10yrs ago.
