ADJUSTING WEIGHT
Helix, Nexus and Eclipse: These bows are adjustable over
a range of approximately 10%. Factors which affect this
include limb length, limb construction, and limb design and
brace height.
1. Using one of the two supplied Allen wrenches; loosen
the tiller bolt locking screw (see Standard Hoyt Dovetail (B)
imageonpg.5).Ifyouplantoincreaseweightyouwillneed
to loosen this screw by more turns than you plan to add to
the tiller screw.
2. Unstring the bow.
3. Turn the weight/tiller adjustment bolt clockwise to increase
bow weight. Turn it counter-clockwise to decrease bow weight.
4. Using both Allen wrenches, and holding the tiller bolt in
place, re-lock the tiller bolt locking screw.
5. Restring the bow.
TILLER ADJUSTMENT
Tiller is a measurement which indicates the weight relationship
of the top and bottom limb. This static measurement has some
effectonbowreactionandaiming.Itiseasilymeasuredbynot-
ing the difference between the top limb butt to the string, and
the bottom limb butt
and the string. The
difference (if any) is
the tiller.
The degree of
desirable tiller will
vary from archer to
archer, depending
upon factors such as
grip pressure, finger
pressure, desired
Warning: Do not adjust weight on any
adjustable bow beyond the limit shown
in the drawing above. The weight/tiller
bolt should never go above flush with
the riser. There must be at least six
threads of engagement between the
riser and weight tiller bolt.

tuning patterns, desired aiming arc, desired bow reaction
and more. As a starting point, it is usually easy to tune a bow
with 0 to 3/8” of tiller (distance from bottom limb to string is
equal to that of the top limb, or less, by up to 3/8”).
Normally, for most shooters with normal
finger and hand pressure, anywhere from
0 to 3/8” of tiller is going to yield a bow
which aims easily without “pulling” high
or low, and which shoots more quietly.
SETTING TILLER
Measure the tiller as shown in the dia-
gramtotheright.Ifyouwishtoincrease
tiller without affecting bow weight,
unstring the bow and add turns to the
bottom limb tiller bolt, then subtract the
exact same number of turns from the
top limb tiller bolt. Re-lock the bolts and
restring the bow.
Do the opposite to decrease tiller. You can increase both tiller
and bow weight by adjusting the bottom limb only.
HELIX & NEXUS ALIGNMENT ADJUSTMENTS
The Helix and Nexus limb pocket design is the most precise,
reliable pocket system available today. This system will main-
tain correct settings in the most severe conditions. Out of the
package, the Helix bow is factory pre-aligned and adjustment
isoptionalwhenusedwithHoytlimbs.Ingeneral,thevast
majority of setups do not require alignment adjustments.
To make an adjustment, follow these directions:
1. Refer to the diagram on page 8 and note the condition.
