RE: G5 meta peep and optix se sight
It looks like an upgraded ME. The knob for adjusting the floating pin is much larger and looks to have the yardage tape on it. On the ME the knob is much smaller and you placed the tape along the site housing; which I found to be not that reliable. Especially since your bow would have to be at a specific velocity that they supply for the tape to work as well as the fact that the weight of the arrow effects velocity at greater distances. You can have a heavy and light arrow with the same velocity when chrono'd that will definitely not have the same velocity at 40 yds. I know that a few people say they use the tape that comes with the sight but for my bow it did not work well.
I'm sure that G5 supplies the tape for the same velocities they do for the ME. However, I'm wondering if you couldn't use the tape from a program to be more accurate.
