I have two teenage boys who live to hunt with me...we use climbers on our public land EXCLUSIVELY...
We scout year around, and we actually take our stands AND bows and practice from chosen locations several times throughout the year. To do this we must wear hunters orange hats as a minimum, AND possess a valid small game license.
Our Summit climbers DO make some slight scuff marks on trees, but even when we KNOW they are there they are difficult to notice.
We ALWAYS take our stands on scouting forays...this year my fourteen yr old has his very own climber, and he has been practicing with it very frequently. His skill level for climbing is excellent, and confidence is VERY high.
In our area, deer populations are extremely low, without climbers and the ability they give to move around our chances at close encounters would be severely reduced.
