I went from a horizontal multipin to this vertical multipin. It worked amazing and helped improve my accuracy. Pins are small yet clear in low light. Seeing the whole target is also nice.
My problem in the field has been watching the pin and the deer, I released when the deer was starting to walk last year and made a bad shot at 15 yards. The horizontal pins covered its head and the other side its tail. The horizontal pin, on my deer target, I can see more of the body. This is very important for any range, bust especially close I believe.
