Need to know what a Via Ferrata is and its working principles?

In this video I will try explain what a Via Ferrata Set is, the differences between a Via Ferrata Set, a Via Ferrata Kit and a Via Ferrata System and the basic function of the Via Ferrata Set.

This is one of the episodes of what I want it to be a stepbystep nonprofessional guide to Via Ferrata.

BE ADVISED! I'm not a professional guide, mountaineer, alpine climber or Via Ferrata climber; only an enthusiastic mountaineer eager to try help and explain my experience so far.

All episodes are as short and concise possible.
