To say that adjustable giths have no place in the hunting field is bordering on outright arrogance or lack of personal experience. I'd have to ask if you have ever spent any real amount of time (months) using one of them or better yet hunted with one to know what they are all about.
I've bowhunted for almost 40 years and used both type of sights. Add a few of the early pendulums to that as well. They all have their place in bowhunting or so many wouldn't be using them.
For most hardwoods hunting with most of today's bows there is very little need of multiple pin sights. Nationwide the average deer is shot at 18 to 22 yards, a statistic that hasn't changed much since I began bowhunting. To that end the vast majority of shots can be done with a single pin sight. Whether it be a multipin sight with all but one removed or an adjustable sight set for a specific yardage is irrelevant.
I've done a lot of testing and practiced what I learned and the fact is any bow shooting about 260 fps or above can be used with a single pin set for 25 yards to cover distances almost 0 to 30 yards with little or no holdover on deer sized game. The high point of the arc will be just about 2" at 18 yards and there will be 3" of drop at 30 yards. Hold the middle of the vitals and shoot. The only thing to be determined is whether the deer is within 30 yards. It's so simple even a cave man could do it No range finder needed..
As with anything in this shooting sport if done over and over for a long period of time things become automatic, just like establishing good shooting form and/or anchor points.
What about older gents like me? I used to shoot multipin sights, but with older eyes and the need of reading glasses those pins are blurry. So blurry that they look like one long multicolored line instead of individual pins. Single pin works OK, even though I have to use a smaller peep and the last few years a Specialty peep with Verifier.
The moveable sight allows me to practice at whatever distances I desire and then set it for that 25 yards for hunting. You know, there are those of us who shoot at times other than hunting season. Fact is I shoot almost daily. But I guess guys like me shouldn't be allowed to hunt because our bow sight has no place in the hunting woods.
