Fletching degree and noise

[Artemas]

Anyone ever notice the noise difference of an arrow in flight using a great degree of twist? For instance, I use 4" vanes with a 2 degree offset. My dad uses 2" blazers with a 3 degree helical. I just switched over to shooting the helical blazer and while shooting my dad said to shoot my other arrows. He then had me stand halfway between him and the target (behind the house for protection) as he shot both arrows. We couldn't believe how much louder the blazers with the helical were compared to vanes. Needless to say I switched back the 5 arrows I put blazers on to vanes. Havnt tested a straight blazer yet but we were pretty sure it was due to the increased spin.

It will increase sound because the arrow will spin faster with the setup you had. Sound waves are created by having the same pattern rotating in the same manner every time. Many tire manufacturers have discovered that by altering the tread pattern with every 4th or 5th block, instead of every one being the same, they can create sound waves that cancel each other out, therefore making the tire quieter. We however, cannot do that because it would cause very erratic flight problems.
All of that being said, a three degree helical will have a much tighter and faster spin and will be more accurate than a two degree offset, due to its high rate of spin and self-correcting flight qualities, and certainly more than a straight fletch of any kind. I tend to put the most spin on an arrow I can get�by the time my target hears it...it's too late.

Ditto , I'll take the increased spin over the slight increase in noise . Deer react to the sound of the bow , not the sound of the fletching .

Yep!! SPIN GOOD!! More Spin, Gooder!!!
