Thanks Steven!
Yes exactly, I'm looking to reassure a potential customer that the tree behind the bag they're punching wont be harmed by the impact of their punch, so asking an arborist/organisation to officially legitimise the safety of the product with a 'stamp of approval' would help illuminate any concern a customer might have.
The pad itself can only be mounted to trees of 85cm circumference or larger which from extensive testing don't even sway in the slightest when the bag is in use.
Hope to hear back.
Kind regards,
Max
