I could never wear a headset - too freaking hot.
Some of the year, sure, hotter. The muffs lift right up. If you have earplugs, with no background noise you could still talk with the crew while the muffs are up. When its not so hot, you can wear plugs or not, under the headsets.
Talked to a friend. He almost had his leg cut off recently by a pull-rope, after the fell, that was being dragged out of the tree. It wrapped his leg. Neither the mega strong rope or truck was going to give. He would have definitely been the loser. Easily prevented by this affordable bit of PPE.
Chainsaw chaps/ paints, $60-400 for something that you will hopefully wear and never use . Buy two headsets and increase safety significantly, and use them a lot of the day, everyday, whether during rigging/ pulling trees, organizing gear, backing into a tight driveway, listening to tunes while raking in the backyard, splitting wood, answering calls, etc. (not discrediting leg protection, but I'm pretty sure I'm at a much, much, much higher risk of injury from something other than a cut to the legs, as bad as it would be)
Paul, I know you're swamped with work and family, so I'm not suggesting YOU make a 'commercial', maybe somebody video-ly skilled. The challenge for people, IMO, is whether or not they will like and get enough use out of the money spent on radios. Until you really experience it, there is no way to understand. I might get a helmet camera soon, and will gladly try to capture the experience, but I have ZERO editing knowledge.
For anybody that does technical work, which is everyone here, they are sooooo nice, and helpful, oh, and did I mention they improve safety.
