GlC maybe one day you can send me a pm on using this thing, I watched a video and read the manual and it just left me really confused with the whole 10x being the only true magnification. Can I just zero at 100 normally and shoot it like a regular scope and it still hold that same zero at different magnifications.
What they probably meant by that is the reticle in your scope, assuming it is something like a mildot, is only true value at 10x. Meaning that the measurement between the center of the crosshair to the center of the first circle is only truly one mil-radian apart at 10x. The actual difference is more or less depending on the magnification. Read up on something known as "first vs second focal planes" or "FFP vs SFP". Yours is probably a second focal plane.
But getting back to the point, while the actual read angle between the crosshair and the next reference point varies with magnification, the position of the crosshair center does NOT move.
Ex: if u r zeroed at 100yards AND your 200yard zero is at the first circle below at 10x, then at 16x the zero at 100 yards at the crosshair will be the same but your 200 yard zero at the first dot will change.
I hope this was clear and helpful.
