The new HX line are Optisan new entry level scopes redesigned to have 25% larger field of view than most existing 3-9X40 in the market. They are built as a family of simple sturdy scope that holds most magnum centerfire calibers such as .270 Win .308, .30-06. Windage elevation adjustment comes with no-tool-required finger resettable zero feature. Choice of reticle for non-AO HX scopes include: (a) standard duplex reticle and (b) BCR reticle (ballistic compensated reticle) both are good for most centerfire magnum caliber. Duplex for shooters looking for classic simple crosshair and BCR for precise holdover marks up to 500 yards. For rimfire / airrifle target shooters we have HX 4-12X40AO ready with parallax free at 35 yards. Reticle comes in enhanced mildot reticle.
The EMD12 is based on the popular mil dot reticle and adds hash lines in between mil dots enabling more precise range estimation hence more precise aiming and holdover. Subtension detail for the HX 4-12X40 with EMD12 reticle as below. Reticle subtensions correct at 12X.
