There are other ways to get a rope in a tree beside climbing the tree. Using a ball and a throwline is difficult to perfect but can save time and potentially, the life of a tree climber.
Sometimes it is too windy to climb trees. Sometimes limbing a tree while climbing will damage structures or plants below the tree. Otherwise, using a ball and throwline can be quicker, safer, and easier. This all assumes, you have a good arm.
Climbing, limbing, and attaching a rope to the top of a tree may take around a half an hour. A tree cutter who is good with a ball and throwline may get a rope in a tree in less than 10 minutes. If they catch a good limb on the first try, the whole process only takes 2 or 3 minutes.
As always, this is a lot harder than it looks. Just ask Bob…
