Thanks. I still don't really know what to get in terms of a red light but I did grab some nockturnal night shooting nocks from the archery store and that has made night practice a lot less frustrating, since I can always find my stick-in-the-dirt arrows right away. Another neat thing about the lightup nocks is since the nock lights up after you release the string, I can see generally where I hit the target from far away, and confirm the straightness of the arrow when I approach the target.. That being said, I'm still amazed at how the 10 yards and 13 yards are still fine, but my skill at 15, 17.5 and 20 just disappear when the sun sets (which In turn leads to the embarrassing walk to pick up arrows out of the dirt). I'm guessing that my nocturnal longshot accuracy will get better with more night practice.
