What do you do if the tree has branches in your way? What do you do if the tree is crooked?
Find one that doesn't or cut the limbs if you can legally do so and/or have permission(private only) .
It seems like the only way a climber makes sense is for "telephone pole" type trees. That's fine, but what do you use for cover?
If the trunk is wide enough it can provide silhouette break up , as can the background clutter . BTW , ever wonder why 15' is considered the minimum height by most hunters ? It's because a deer's vision extends in a truncated cone whose maximum diameter is only about
12' tall unless they look up , if you don't move or otherwise draw attention to yourself they won't see you anyway .
I don't know about your area, but around here those telephone pole trees are very few and far between. And if you do find such a tree, odds are it's not where the deer are going to be.
If you can't alter those trees to suit a climber then a climber is not for that situation and a lock on and climbing gear is what you need . If there are no deer there anyway then you're wasting your time hunting that spot .
