Check out the Trophy Ridge React sights. I use the React 5.
The setup is super quick. Get the 20 yard pin nailed. Then dial in the 30y pin.
The sight is designed so that the 20y pin is independently adjusted. The 30, 40, 50 & 60y pins are mechanically connected ingeniously so they all adjust simultaneously with 1 dial, but the longer range pins move comparatively further with the turn of the dial.
It's ingenious. As long as the bow shoots within a certain speed range, the difference in drop between the 20 and 30y pins will determine how much the arrow drops at the longer ranges, hence, the design ensuring you never pick up your bow, to find all the pins at the bottom because they weren't tightened enough.
Just dial in the 20y and 30y pin, then check any of the others (40, 50 or 60 yard pins). The closer you dial in the farthest pins, the more accurately it dials in the nearer pins.
Since I personally won't take a bow shot past 60y, the React 5 works great for me.
For 3D competitions or folks taking shots out further, they have the single pin, dial for range, React One.
For a peep, check this one out
NiteHawkArchery peep sight
Watch the video explaining diffraction and how this peep works. I can honestly say, after using it, it works exactly the way the designer claims it does.
In fact, after using the NiteHawkArchery peep on my Obsession Evolution, I've wondered why no one's ever made a rear BUIS with a "+" shaped aperture. I've even considered figuring out how to mod my irons to have a "+" shaped aperture.
The "+" would make consistently centering the tip of the front sight post instinctive, and the low light benefits would be a definite plus.
