Gather 'round children, and let uncle Limb It tell you a story.
On Thursday, I was chipping a particularly nasty piece of ash, quite hard, lots of 90 degree corners, plenty of things to get snagged on. Our company only has a 7" chipper, so there is a lot of babysitting that needs to be done to ensure the pieces all make it into the back of the truck. As I was getting this piece into the chipper, a piece of the branch managed to snag onto the back pocket of my overalls and start pulling me towards the machine. Not really a huge problem, as I had my hand right next to the crash bar. I back the piece out a bit which would normally get me untangled. It didn't work, I was stuck good. It had managed to twist its self into the top of the back pocket and I wasn't able to free myself. I was in no danger of getting dragged into the machine, But I really couldn't get myself free in any easy, or graceful way.
My groundie was only 15' away, but he had his back to me, sharpening a saw. There's no way that I would have been able to yell over the sound of the machine, and have him hear me.
All I had to do was hit the button and tell him that I needed him to bring over some loppers. Had this happened last week, I would have had to wait for him to notice I needed him, get him to come over, ask him to get the loppers, and then wait for him to get back with them to make the cut to free me. With the Sena's, this was all over in less time than it has taken for you to read this. Money really well spent.
