Let's check the necessary material and see the differences between these two worlds:
Via Ferrata
Via ferratas are artificial paths equipped on more or less rocky walls to facilitate their ascent. They require ad hoc designed equipment to be able to overcome the various passages in safety. To make a via ferrata, we need certified personal protective equipment. We can list them starting from the bottom: the boots, the harness, the via ferrata set and the helmet which are indispensable equipment. Furthermore, it is always better to have a backpack and special gloves with you that can help us in the progression.
The via ferratas are divided according to the difficulties encountered along the way, starting with F (easy) routes and then finding the PD (not very difficult), the D (difficult), the MD (very difficult) and finally the E ( extreme).
Climbing
When you start climbing outdoors, you start from the crag with the so-called single pitches; when you reach the end of the pitch you usually reach a chain, that point is called a belay and from there the abseil controlled by the partner who is at the base of that pitch begins. Each shot has difficulties that determine its "grade". The more you climb in grade, the greater the technical and physical ability of the climber must be.
In the world there are different scales, usually the French scale is used which goes from 1 to 9, the numbers are followed by the lowercase letters "a", "b" and "c", the symbol "+" to indicate the intermediate degrees. The difficulty is generally estimated by who opens the pitch or the route (that is, by whoever climbed that section of rock first). In general, the degree gives an idea of the difficulty that we will find along the pitch.
To start we will need climbing shoes, harness, helmet, sling, carabiners, descender and an expert companion!
