When it isn't possible to get prone or find natural shooting support in the field, we use our pack and trekking poles to build rock-solid shooting positions. In this video, Mark demonstrates how to use an Exo Mtn Gear pack and his trekking poles (equipped with Wiser Precision Quick-StiX adapters) to shoot from sitting and kneeling positions. With some practice, this type of position can be built quickly and used effectively for many hunting shot opportunities.
