Nikon PROSTAFF P3 CROSSBOW Instruction Manual

Crossbow scope/Lunette de visée pour arbalète

3×32

Instruction manual/Mode d'emploi

Congratulations on your choice of a Nikon crossbow scope. Your new scope is the nest example of Nikon’s rugged and durable construction and precision bright optics; important qualities for a serious crossbow shooter’s

scope.

Whether you use your scope for target shooting or for hunting, the procedure for mounting is identical. A set of high-quality steel mounting rings which have a standard diameter of 1 in. (25.4 mm) are required to mount the scope. Follow the ring manufacturer’s instructions for mounting procedures. After mounting the scope on your crossbow, follow the procedures for reticle alignment.

WARNING:

IMPROPER MOUNTING OF YOUR NIKON SCOPE CAN CAUSE SERIOUS INJURY. THUS IT IS IMPORTANT THAT YOUR NIKON SCOPE IS MOUNTED PROPERLY BEFORE USING. TO ENSURE PROPER MOUNTING OF YOUR NIKON SCOPE, PLEASE HAVE IT MOUNTED AND/OR CHECKED BY AN EXPERIENCED GUNSMITH BEFORE USING. THE USER ASSUMES ALL RESPONSIBILITY AND LIABILITY FOR HAVING THE SCOPE PROPERLY MOUNTED TO A CROSSBOW AND FOR USING THE SCOPE PROPERLY. ALWAYS CHECK THE CONDITION OF YOUR SCOPE AND YOUR MOUNTING SYSTEM BEFORE USING YOUR CROSSBOW.

Caution

(1) Do NOT look at the sun through the crossbow scope. It will permanently damage your eye. This precaution applies to all optical devices, such as cameras and binoculars. (2) Do NOT mount this scope on any rearms because this is a crossbow scope. (3) The crossbow scope is eectively sealed against moisture and dust. You may use your scope safely either in the rain or in dusty climates. To preserve the appearance of the scope, we recommend that it be dried

and cleaned prior to storage. Use a soft cloth for cleaning metal surfaces and use photographic lens tissue to clean the scope’s lenses.

When setting the reticle for shooting or hunting, you should determine your standard range and then adjust the reticle based upon that target distance. For targets which vary from that standard distance, according to personal preference, you may simply adjust the position of the reticle in relation to your target, or you may wish to use the procedure for trajectory compensation. We hope that you will enjoy your new Nikon crossbow scope for many years to come. Enjoy using it, and above all, always follow safe shooting procedures.

3. Instructions

(1) Focusing

1 Look through the eyepiece with your eye positioned about 3-4 in. (7.5-10 cm) away from the eyepiece to see the BDC 60 reticle

(Fig. 3). Be sure your eye is positioned with proper alignment and with proper eye relief, otherwise the view will “black out.”

2 Point the objective end of the scope at the sky (do NOT point it at the sun) or at a plain unpatterned wall.

BDC 60 reticle

3 Turn the eyepiece adjustment counter-clockwise and then turn it clockwise until the reticle appears sharp.

Notice: Reticle images shown in this manual are representation only. Actual images may vary.

(2) Adjustment of the crossbow scope

Sighting through the crossbow scope, align the crossbow with your aiming point on the target and shoot a trial bolt. If the bolt does not hit the aiming point, adjust the elevation and windage adjustment turrets as follows:

• If the bolt hits under the aiming point, turn the elevation adjustment turret (counter-clockwise) in the direction of the arrow marked “U” for up. If the bolt hits high, turn the elevation adjustment turret (clockwise)

in the direction of the arrow marked “D” for down.

• If the bolt hits to the right of the aiming point, turn the windage adjustment turret (clockwise) in the direction of the arrow marked “L” for left. If the bolt hits to the left of the aiming point, turn the windage

adjustment turret (counter-clockwise) in the direction of the arrow marked “R” for right.

• After the reticle has been adjusted to the point of impact, replace the turret cap for both the elevation and windage adjustment turrets.

Note:

• The windage and elevation scales of PROSTAFF P3 CROSSBOW scopes are calibrated in divisions of 1 minute of angle (MOA) with a click at intervals of 1 minute of angle (1 division).

• When adjusting the reticle to the point of aim, remember that 1 minute of angle equals approximately 1 in. (2.54 cm) at 100 yd. (91.44 m).

Therefore, if the impact point is 2 in. (5.08 cm) low and 1 in. (2.54 cm) right at 100 yd. (91.44 m) parallax setting, you should adjust 2 minutes of angle up and 1 minute of angle left. In the case of 60 yd. (54.86 m) parallax setting, the adjusting value is 3×.

(3) Zero resetting of adjustment turret

The elevation adjustment and windage adjustment turrets have a retracting system. After the reticle has been adjusted to match the point of impact, pull up the elevation adjustment or windage adjustment turret to disengage. The turret can now be turned freely. Align the zero number to the index line to set the zero setting, and then release the turret. The turret automatically retracts to the original position.

Utilizing the BDC 60 reticle

The BDC 60 reticle was specically designed to match the trajectory of today’s modern crossbows and provide bolt drop compensation out to 60 yards, which we feel is the maximum ethical range for crossbow hunting. It is important that you determine the actual velocity of your crossbow using a chronograph as manufacturers’ specications can vary. Most local archery pro shops have chronographs readily available for you to obtain accurate velocities from your set up.

The reticle is designed to be zeroed at 20 yards with a 400 grain bolt (including a 100 grain eld point, bullet point or broadhead) with the crossbow having an average velocity of approximately 305 fps. The ballistic circles would then provide bolt drop for 30, 40, 50 and 60 yards as seen on the next page.
