10-20 minutes depending on early or late season?
I always found climbers the fastest method for me.
In North GA we have a ton of straight limbless trees and since I use the LWHC as my climbing method and platform my setup time is fairly short at around 10 - 15 min depending on hunting height. I am hunting exclusively public ground right now, and many spots for the first time. Honestly, I spend way more time trying to figure out which tree to climb than I do actually climbing. I really need to speed up that decision process.
