For grins, I took my small 40x rifle scope on my daily walk up a very steep hill- 1/3 mi @ 12-14% grade.
It gets my HR up pretty good.
@ summit I sighted scope on various objects and attempted to keep it still and even control breathing.
I was not very good at it and think that I will need a lot of practice to hit a biathlon target.
Good test...
