I got a question from Carole, who asked: “What are your thoughts on using a sight with a pin in the center (recurve sight) compared to one without a pin, just a tunnel? I have read that the human brain is excellent at centering a circle and wondered if it would be more ‘natural’ to allow the brain to center the sight on the gold and therefore more relaxed on the eye? I have used both and (think) I prefer without the pin, but am interested in your opinion.”

Okay, here’s my opinion. I think the jury is still out on this one, so I would call it a matter of personal preference at this point. By all means, do try both types, noting how each affects your sighting (mentally as well as physically).
The same question comes up on the compound side in the form of having a central pin (usually fiber optic) or just an applied ring on one’s scope lens. (There are commercial sets of decals for application to the scope surface with various thickness and colors of loops.)
My thinking at this point (remember this is premature as we have almost no real information on this topic, just opinions) is it depends on the kind of person you are. Using me as an example: I am a bit easily distracted, a bit shaky, and a bit nervous. I find the loops preferable for the following reasons: a small pin looks more jittery than a larger loop, which leads me to press to try to be more steady, which makes my steadiness worse, not better. One must relax into a clam state of steadiness, not “try.”
I use a bright green, thick, fairly large loop decal on my compound scopes. Green is not a color that shows up on target faces much so a good deal of contrast is there. The thicker loop makes it easier to see, the larger loop avoids a problem with small loops, namely that as target sizes change with distance, if you have a small loop, you can be floating around in the middle not knowing where you are. Take a Metric of American 900 Round. At 30 yards/meters, a small loop may only show you gold on the 122 cm multi-color target. So, where in the gold are you? Do you look for the dividing line between the 10-and 9-rings? Do you move around, looking for the edge? Similarly, if the entire gold, or center spot whatever the color, barely fits inside the loop, there is a tendency to try to fit it exactly which leads to over focusing on aiming too precise to sustain.
A large loop allows several rings or a smaller central spot to float in the middle of the loop using the brain’s automatic centering function to your benefit. (This function is hardwired into our brains. It is used for distance estimation and other functions and it is normal for most all people.)
On the recurve size, I prefer a larger loop than the commercially available ones that seem a bit small to me. (They are easy enough to make and I also paint the front edge bright green.)
So, when you try these options, in the back of your mind (that’s a metaphor, not literal suggestion) keep track of whether your aperture helps you to feel calm. In my case, the thick green ring helps me locate the loop in my visual field easily, in all lighting conditions, shows little perceived motion when aiming which provides a perception of steadiness, which then leads to relaxing a somewhat jumpy archer. If you, on the other hand, are rock steady, mentally calm person, you may find a pin easiest to line up with your point of aim.
It doesn’t hurt to try a number of variations to see what works best for you. Pin, no pin. Small loop, big loop. Different colors of loops. This doesn’t all have to happen at once (unless you are hyper-competitive), but over time, these are things to “give a try” at.
PS This is also wrapped up in another discussion: should you be looking at the bow sights aperture or the target. Both will not be in focus at the same time. That question is for another time.
