I never thought about the hunter safety system until now …never replaced that ever,yikes !! I’m leaning toward just replacing them it’ll give me the peace of mind and allow me to feel more confident. I know it’s probably not needed but oh wellRopes can last. Learn how to inspect your rope by watching videos like listed above. Untie knots each season and you can also flip your ropes. But if replacing your ropes each year gives you peace of mind then that's good but in most cases its not necessary. I use HTP which is inexpensive rope but it won't get replaced until I see signs of needing replaced. Think about how many years you used your Hunter Safety System tether if you were a treestand guy. Not saying it should not have been replaced but I bet some of those tethers were 10+ years old.
Thanks for the info !!Here’s a good read from weighmyrack which is a climbing website:
They echo a lot of what I was taught in the Navy when we inspected line and cordage, especially hawsers(the super thick white line used to tow and tie up ships). I have no problem using my rope for quite awhile and I rappel so my one line does it all. I’m also meticulous with it and inspect it every climb so it gets replaced as necessaryWhen To Retire A Climbing Rope
