In case you climb on and something breaks. Maybe you didn't get a ratchet quite tight enough or another piece gives out. If you are attached with your tether and lineman belt, there's less chance you'll get hurt. I should have been more clear about that. My apologies. Great catch!Great video, thanks for sharing.
I didn't get why you say tethering to the tree before mounting the platform is "the most important thing you can do for safety"?
