Model 512. XBOW was designed with the crossbow hunter in mind. The XBOW utilizes the unique properties of holography to create optimal range scaling data in a heads-up display. A pre-calculated ranging scale is projected on the target and measures the back to the belly of a standard whitetail deer (18"). Simply position the base of the scale on the belly and read the yardage line that crosses the back. This integral ranging pattern eliminates unnecessary body movement or added noise while in the stand since the ranging and aiming information are both displayed in the same sight picture.

RETICLE The 512.XBOW model offers four (4) Ballistically compensated 1 MOA aiming dots (see figure on left). These dots will provide precise points of aim throughout the range of your crossbow. In addition to the aiming reticle, an Integral Range Finder is included to assist in determining the distance between you and the deer. This range finder can provide distances from 20-60 yards in increments of 10 yards.
HOW TO USE THE INTEGRAL RANGE FINDER The unique properties of holography have made it possible to create optional range scaling data integral within the heads-up display. The image of a pre-calculated ranging scale is projected out at the target plane and measures the back to the belly of a mature whitetail deer (18"). Simply position the base of the scale on the belly (see Fig. 2) and read from where the back intersects the scale – it’s that easy. With the integral ranging pattern, there is no unnecessary body movement or added noise while on stand. Range information is displayed within the sight picture for when you are ready to shoot.
ZEROING THE SIGHT The top dot must be zeroed at 20 yards for the ballistic calculations to work. To do this, place a target out at 20 yards and safely fire. Adjustments in Windage and Elevation can be made on the right side of the sight. Keep in mind, each click represents 1/2 " adjustment at 100 yards. Once the top dot is zeroed, locate the Ballistic Wheel included in the packaging and align your crossbow speed (fps) with the opening of the window. This will indicate what each of the remaining dots will be zeroed to. To confirm, move to those distances and safely fire.
NOTE: Ballistics calculated using 349gr bolt and 100gr field tip. Different variations may affect POI (point of impact).
