The Koç Nock was specially designed for horse archery.
Its helical shape allows nocking regardless of the direction in which the Koç nock is presented to the string.
Big or Small? Our opinion
The Horse Archery Shop team would advise you on the big model. To achieve rapid nocking, the width of the nock is very important. It is this shape that allows a good grip and to be in front of your string (it can be more or less important depending of your technic).
If you are in front of your string when you nock, the shape of the Koç Nock will only be useful to save your mistakes from time to time.
So to summarize: With the small one you will find it more difficult to nock in front but the shape of the koçnock will save you. And with the big one, you will nock more easily in front and the shape of the nock will also save you in case of error.
So the choice is easy for us 🙂
