Running tapes is just the beginning with all of the features you expect from even the most expensive mechanical devices, but, with awesome features that are possible only with a digital tape number processor.

Using this tool, you can do amazing tasks that you will never be able to do on that plastic or metal monster that is taking up desk space sitting next to your computer.
