FIXED BLADES VS. MECHANICAL
INSIGHT TO SELECTING THE RIGHT BROADHEAD FOR YOU.
In the past there has only been one choice when selecting a broadhead and that is the fixed blade type, until recently. In the last few years technology has advanced allowing the bow hunter to attain a large selection of mechanical broadheads to choose from. What type of broadhead each person chooses has more to do with the individuals skill level and bow specs than most hunters realize.
Fixed Blade Broadheads
Fixed blade broadheads have always been the broadhead of choice. A fixed blade broadhead is a broadhead with blades that are fixed in the open position. This type of broadhead cuts on impact which is a more efficient way of starting the wound channel, the blades cut into the animal and prevent the wound from closing, allowing the hunter a more detectable blood trail. Fixed blade broadheads also tend to be more durable than their mechanical counterparts. Since the blades are fixed within the head itself and are unable to move they are lasting and reliable.
Fixed blade broadheads also have higher penetration than mechanical broadheads, due to the fact that they cut on impact and do not waste energy opening their blades. Neither choice is perfect yet the only negatives with fixed blade broadheads is they have a tendency to plane when shot out of high speed bows and can be thrown by the wind. Arrows with fixed blades are also difficult to tune. These negatives can be reduced drastically by aligning the blades with the fletching of the arrows.
Mechanical broadheads are relatively new, and are fast becoming popular in today‘s hunting world. The up side to this hip new design is that mechanical broadheads have a greater tendency to fly straight and shoot similar to field points, this is because the blades of a mechanical broadhead are unexposed in flight and therefore are not affected by wind in the way fixed blades are. Mechanical broadheads also offer larger cutting diameters which aid in faster more humane kills.
Mechanical broadheads do have some negatives, they tend to require a faster arrow speed to ensure penetration, this is due to the fact that they loose energy when they open. This type of broadhead can malfunction when opening and has been known to be deflected off bone.
An Individual Choice
From our reading above we now have more of a realization that choosing the right broadhead depends more on you and your bow than on the broadheads look or packaging. An individual shooting a slower bow, generally 250 fps or less the fixed blade variety is the best choice for your bow. An individual shooting a very fast bow who limits their range, may want to try using these new mechanicals for they can offer many advantages.
No matter what broadhead an individual chooses, equipment does not improve a faulty shot, practice often to ensure a happy hunt.
