I just took a 4 1/2" grinder and ground a mark in each bar at 16" from the tip. It's easy to see and quick. Sure you need to turn the saw sideways but it beats having to carry something. I thought about mounting something to one of the dogs. I looked at the cut-rite attachment but it doesn't look like there's a spring on it. If all you're cutting is perfect logs then it wouldn't be an issue but if you're cutting around branches and had to keep taking it off I think it would be tiresome.
I tried that turn-saw hand dance about 3 cuts, that was enough, I just want to cut when it's time to cut, full throttle wide open, getterrrrrr done. Spring not needed, that nylon rod will bend around in a circle, in the brush, top of tree, on the edge of Grand Canyon, no problemo if you can unplug an air hose you can unplug the Cut Rite, and that's the most important part, on quick, off quick, now I'll collect my commission$$$$$$$
