Hawke Optics XB30 Crossbow Scope - Manual

Congratulations on the purchase of your
new Hawke XB30 SR crossbow scope.
Your new scope is a high performance
optical product designed to provide
years of service. Please read these in-
structions carefully before use.
WARNING: NEVER LOOK AT THE SUN WITH
THIS SCOPE AS IT MAY PERMANENTLY DAM-
AGE YOUR EYES.
CAUTION: BE SURE THAT THE CROSSBOW
IS NOT LOADED WHEN MOUNTING THE
SCOPE. ALWAYS PRACTICE SAFE CROSS-
BOW 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.
MOUNTING THe SCOPe
Support your un-cocked crossbow on a
sturdy surface and position a good quality
set of rings on the crossbows scope mount-
ing rail. Tighten the ring clamping bolts to
the scope mounting rail to 30 inch pounds.
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 rings to be
moved along the scope rail.
With the top ring screws still loosened
slightly, rotate the scope so that the hori-
zontal crosswire is parallel with the cross-
bow string and limbs, when viewed
through the scope. Next, tighten the top
ring screws to 16 inch pounds 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.
While looking through the ocular end of
the scope, view the reticle on a neutral
background such as a white surface or
the sky. Turn the adjustment ring until the
reticle is in focus; it should be sharp the mo-
ment you glance through the scope.
INITIAllY zeROING YOUR 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 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 im-
pact are the same. At this range, each click
equals 1/10th of an inch. (10 clicks to move
the impact 1”) When you are happy with
the 20 yard zero, replace the turret covers.
CAlIBRATING YOUR SCOPe TO THe
CROSSBOW
Adjusting the speed selector also adjusts
the magnification. Start by setting it to the
manufacturers advertised speed of your
crossbow.
Move to a measured 30 yards from the tar-
get. Using the 30 yard marker in the scope,
(the second crosswire down) shoot the
crossbow at the target.
If the arrow impacts the target high, turn
the speed selector higher and the next
arrow fired will impact the target lower. If
the arrow impacts the target lower, turn the
speed selector lower and the next arrow
fired will impact the target higher.
Once the 30 yard crosswire is sighted in the
scope is now calibrated to your crossbow
and all of the other aiming points will be
correct. At this time, the speed/magnifi-
cation selector will need to remain in this
position to keep the scope and the cross-
bow calibrated to each other.
Crossbows with speeds over 450 fps and
using a lighter arrow combination may
require a main crosswire sight-in point of
30 yards instead of the normal 20 yards.
This will require calibrating the scope at 40
yards to compensate for the flat trajectory
of this combination of components.
IllUMINATed ReTICle
The control rheostat for operating the
illumination is positioned on the left side of
the saddle.
The central aim points can be illuminated
in red or will be visible in black when set in
the off position.
The controls have a positive Off position,
an ON position and an infinite rheostat ad-
justment from very low for use in low light
conditions to very high for use in bright
conditions.
The battery is a CR2032 3V coin style. This
is positioned underneath the rheostat cap.
When replacing the battery always ensure
the positive (+) is facing up.
RANGe fINdING WITH THe ReTICle
The XB30 reticle can be used to bracket the
target and calculate the range. Brackets
of 4”, 8”, 12” and 16” can be achieved at 20
yards. Brackets of 4” and 8” can be achieved
at 30, 40, 50 and 60 yards - only with the
speed set at 450 fps (5x mag).
