Good work, but in the long run, that rod will break suddenly. So, set a safety belt also. Then it will be perfect.Wow, looks just like the climbing tree stands we hunters have used for the past 30+ years. Next, you should "invent" the full body harness and prusik hitch climbing ropes we use in case of equipment failure. Oh, and then "invent" a Strain Relief Safety strap to use in case the bottom half slips or is dropped. Make sure you "invent" some foot straps and/or stirrups so people can wear boots instead of built-in flip-flops. Maybe also "invent" a tie line between the top and bottom halves in case of mishap so that the bottom falls no more than a few feet and gives the operator a chance of recovery. Then, maybe "invent" a Manufacturer Safety consortium like the Treestand Manufacturers Association to ensure safety improvements are shared. Finally, you should reinvent the wheel.
