As a precaution when using a snatch strap (not around a tow ball) you can always use a tree trunck protector (3m) shackled to one rated recovery hook on the vehicle to be snatched and the other end of the tree trunk protector schackled to the snatch strap that is attached to the vehicle being recovered (that is on a second rated recovery point). That way if the recovery point or shackle give way on the end of the snatch strap, then the snatch strap will be limited by the tree trunck protector (to 3m travel). This will help minimise potention danger/damage of the flying snatch strap with a shackle tied to it. It will however travel at least 3m and take anything out in that area, so good idea to keep everyone as far away as possible.
