Be attentive to your equipment, I had a climber come apart during a youth day safety course. We covered daily and seasonal inspections then went right out and put 10 or more years worth of use to the stand and it came apart with a 12 year old boy descending the tree.
The safety system did its job, but it should never have gotten to that point.
The sling style seat slipped out of 3 buckles at once just as the lad was sitting back. He would have gone out backwards had the saefty system not caught him.
Use safety systems from ground up and down. Many only tie in after sitting in the hunting position. AND use a haul line for all equipment.
