Fixed-Blade Broadhead Tuning
How To
Do It
If the broadheads
are not flying the same as field points the arrow rest needs to be tuned.
For example broadheads
fly high and left of zero for field points. This tells that the broadhead tipped arrows are coming off the bow a little
high and left.
To correct first move rest to the right until
broadheads are hitting straight high. Secondly move
the rest down. Continue adjusting until broadheads
and field points hit the same spot.
Sights may need to be adjusted. That is
fine because broadheads and field points are now
hitting the same spot.
Why it works
Arrows tipped with broadheads
are much more susceptible to wind planning because 3 or more blades act as “wings”.
As the arrow reaches the peak of its trajectory and begins its downward arch
the wind can catch the “wings” (blades) and push it downward causing erratic
flight. (Arrows drift right, left, down or even up.)
Adjusting the arrow rest usually corrects the problem.
Other notes
As the strings/cables age and creep
(stretch) this tuning may need to be repeated.
Broadhead
flight may vary from bow to bow.
Older slower bow models do not produce
as much energy thus field points and broadheads may
have flown consistently. In addition variation in manufacturing tolerances of broadheads affects flight. For this reason a broadhead company like G5 is a good choice for conventional
broadhead because of their high standard – accepting tolerances
of no greater than .001. (We recommend the Montec or
Striker models.)
Another alternative is to shoot a
mechanical broadhead that flies more like a field
point. (We recommend Grim Reaper Razortip.)
