A few years ago, I had to tattoo, in both ears about 50 head of yearling bulls. I had them being fed at a neighbor's place. I told the fellow helping me that this will be a lesson in frustration, because they sling their heads, or move right when you are getting ready to tattoo. I told him this would probably take over half a day. As it turned out, my neighbor had a Hi-Qual hydraulic chute with a neck extender. It held their head perfectly still, and we branded and tattooed 50 of these bulls in two hours. It was the easiest thing I'd ever done, compared to tattooing in a regular chute. I guess it just depends on how many cattle you own, and what your purpose for a head holder would be. If you are having to work on their heads quite a bit, such as tattooing in a registered operation, or if you have a large herd, or possibly a feedlot, it may be a good way to go. The Hi-Qual seemed to be a good on.
