You know I don't do tree work for a living but I do cut wood every year to heat my house and even if I'm not felling a tree, when I'm cutting wood in the woods, I wear a safety helmet which has hearing and eye protection built in. I wear it because I have had close calls and a friend who had a branch fall on him and he is still disabled from it. Take a look up in the trees around you some time and look at all the dead branches and what not hanging just above you ready to bump your noggin. You ever walk in the woods and see a branch just sticking in the ground straight up? That sucker fell and what's the rate that gravity pulls on any object?? That branch is in the ground 4-6 inches just from falling, can you imagine that sucker pile driving you right in the center of your skull? I actually started thinking about it just this season as a matter of fact for saddle hunting and my pride and ego get in the way but I think a light operator helmet like the military uses may just be the right mix of protection and lightness to wear saddle hunting but also to add NV to it and use in the predator calling realm as well to justify the expense. The truly good helmets are hundreds of dollars but may be worth the initial investment in the long term and lifetimes of hunts from above. I'm not completely closed to the idea and think it is a potential market as well, especially for the self-filmers. I'm a NYS Certified Hunter Ed, Bowhunter Ed instructor and the greatest problem right now related to hunter safety is tree stand falls. In a majority of the cases, people simply do not wear any kind of fall restraint while hunting at height but there are incidents every year where a stand just came apart or a ratchet strap ripped etc. In 2017, the first year NY started tracking tree stand safety incidents, we had more deaths from hunters falling than from getting shot! Again, most of it was related to people just being lazy and not wearing a harness or restraint of some kind but people are falling and dying every year. The reports do not mention how they died just that they died as a result of their falls. Just some information to ponder and consider. Have I worn a helmet while hunting? No. Will I in the future? I might!!!
