When mounting 2blade broad heads, do you mount them vertically or horizontal.
If you mount them vertical, they do not interfere with your secondary vision.
If you mount them horizontal, You would think that it would be more stable because of wind resistance and when the arrow flexes away from the riser.
There should be a study done somewhere?
Lately, I have just put them on a dixon broadhead aligner and left them where they are tuned.

From an arrow flight perspective, if your arrows are properly tuned, vertical versus horizontal is a non-issue. They will fly the same. Where it comes into play is how they look in your peripheral vision, and for that reason, I mount all of mine the same way.

Always trust the spin test for final position especially since switching to woods. When I shoot, I never see the arrow.

I mount mine however they spin best.

It's all about what you like I prefer vertical do to looks.IMO it doesn't matter in flight at all.3R has a good video an mounting glue on heads and you should check it out.

I like them horizontal, so if I overdraw the bow it doesn't hit my finger. If the back corner is sharp, it can cut.

They go on any which way as far as I am concerned-does not make any difference.

I mount mine just off vertical aligned with one of my hen feathers...  When at full draw and with the bow canted the broadhead seems to disappear.  At least I don't notice it.. I do not want to see it....

I like them horizontal.  It seems to interfere with my sight picture less that way.

I mount them vertical. Being mostly a gap shooter I use the broadheads tip as a "sight" by aligning it with the animals front leg. The tip of the blade is point on at 15yds. and the ferule is point on at 25yds.

I prefer mine horizontal.

I take O.L.'s advice and mount mine horizontal.
Reasons:
1. A bad release will be plucking the string which would move the arrow on a horizontal plain thereby letting it plain off target if vertical.
2. Arrow paradox is side to side ... again letting it plain off target if vertical.

Saying that ... I'm not a good enough shooter to tell a big difference so it's mostly theory that I choose to use from someone a WHOLE LOT more experienced than me.

I do half vertical and half horizontal.. That way I am in agreement with everyone half of the time.
For myself I trust the spin test.

I ALSO THINK THE MAIN THING IS TO HAVE THEM SPIN TEST ON YOUR ARROW WITH OUT ANY WOBBLE AND WELL TUNED ARROW. AS FAR AS THE WAY THEY ARE MOUNTED, I LIKE TO MOUNT THEM KINDA DIAGNALLY. I SHOOT MY BOW SLIGHTLY CANTED AND WHEN I DO THIS I CAN SEE THE BROADHEAD WITH MY SECONDARY VISION AND IT'S JUST AN EXTENSION OF MY ARROW THEN. JUST M.O.

I wondered about that years ago, tried them both ways, couldn't see a difference in flight or accuracy and ended up choosing vertical.

Why?...because it seems in all the old pictures and drawings of archers at full draw they were set up that way, and it does look good.

How's that for a scientific approach!

What PowDuck said.  A bad release will show up less mounted that way.  But - it still has to spin true.  H

Ground and PowDuck, that is what I was thinking recently. I have not give it much thought in the last 10 years or so. I will be experimenting in the next couple of weeks.

Horizontal for me.

Interesting this thread came up today, as I just got a broadhead target for a gift and had to try it out. My broadheads lined up every which way and really I could not tell the difference at all when shot. I don't gap shoot, so looking at the arrow tip is a non issue with me, but I can say that none of my arrows shot any differently and I was hitting what I was looking at with all of them. If I had a preference, I would mount them horizontal as they totally disappear from my peripheral vision.

I just spin um true and don't worry about it from there.
