INSTRUCTIONS FOR USE
WARNING: NEVER LOOK AT THE SUN WITH THIS SCOPE - IT MAY
PERMANENTLY DAMAGE YOUR EYES.
CAUTION: BE SURE THAT THE CROSSBOW IS NOT LOADED WHEN
MOUNTING THE SCOPE . ALWAYS PRACTICE SAFE CROSSBOW
HANDLING
CAUTION: ALL SHOOTING SHOULD BE CARRIED OUT AT AN APPROVED
RANGE OR OTHER SAFE AREA.
CAUTION: BE SURE THAT THE SCOPE IS MOUNTED FAR ENOUGH
FORWARD - ITS REARWARD MOTION MAY INJURE THE SHOOTER
WHEN THE CROSSBOW RECOILS.
Fitting the scope and mount to your crossbow
Support your un-cocked crossbow on a sturdy surface and position a good
quality set of ring mounts on the crossbows scope rail. Tighten up the side
bolts.
Determine the best eye relief. This is achieved when the crossbow is held
in your normal shooting position and a full sight picture is viewed without
straining or stretching your head or neck. This optimum adjustment may
also require the mount to be moved along the scope rail.
With the top ring screws still loosened slightly, rotate the scope so that the
horizontal crosswire is parallel with the crossbow string and limbs, when
viewed through the scope. Next, tighten the top ring screws and double
check that the scope hasn’t moved from its optimum position.
Adjusting the ocular lens
The ocular lens housing has a fast focus thread that quickly adjusts to
make the reticle as sharp as possible when viewed through the scope.
Set the focus of the reticle in similar light conditions and at the
approximate range at which you expect to use your scope.
Try not to stare at the reticle to get it in focus; it should be sharp the
moment you glance through the scope.
Initially zeroing the scope
Choose a place to shoot your crossbow with a safe backstop and ensure
that no one can step unseen into or in front of the firing line.
Initially, place a paper target on the backstop at about 10 yards and take a
shot at its center.
Remove the dust covers from the windage and elevation turrets of the
scope and make a suitable adjustment to the turret to bring the point of
impact (POI) closer to the point of aim (POA).
For example - if the arrow has landed lower than required; rotate the
elevation turret counter clockwise to raise the point of impact. A high
impact point requires a clockwise adjustment.
Both turrets move the POA a 1/2 minute of angle per click – this is equal
to a 1/2 inch at 100 yards or a 1/20th of an inch at 10 yards.
After achieving an approximate zero at 10 yards, move back to a
measured 20 yards and continue adjusting the turrets until the top cross of
the reticle and the point of impact are the same. At this range each click
equals 1/10th of an inch.
When you are happy with the 20 yard zero, replace the turret covers.
