Steve called them, "a multitool of the backcountry." They can prevent injury, allow you to hike further with less fatigue, support a shelter, and enable you to shoot a rifle with more stability from various positions.

In this video, Steve & Mark discuss why backcountry hunters should use trekking poles, what to consider when purchasing trekking poles, the mistakes that people make when using trekking poles, and how you can use trekking poles for more than hiking.
