I use Tru-Glow Sights. I have an older model Eye.Site4000 on one bow and a newer model Eye.Site5000 on another. Both are all metal and both have the Tritium night sights for my 20yrd pin. Theseare great sights for hunting. They will run you around $40.00 to $60.00 with the tritium pin. The 4000 series are more basic than the 5000 series sights in that they have less micro adjustment. I actually prefere the 4000 series over the 5000 because it is lighter and very solid.

The tritium pins need no light source to glow, they glow constantly. If you are shooting over an open field with plenty of natural light source, I don't think you will need them as when you run out of light it's probablyprior to,or past legal hunting hours anyway. But if you hunt in heavy cover youwill find the light will not be as bright in the early hours or late in the evening. This is where theTritium pins really shine(pun intended).

In myopinion there is no need for a 30yardTritium pin because (in my neck of the woods) you will not be able to clearly see your target at that distance when the light is fading.There is nouse in seeing your pins if you can't see your target.....But, up close (20yd and in) they will allow you to hunt just at the start or right up to theend of legal hunting hours while in heavy cover. I havehad situations where I still had approx.10mi +/- of hunting time leftand my 30 and 40 yard pins (regular fiber optic) were dark but my Tritium pin allowed me to make a clean kill.

So if the situation is right, a Tritiumpinned sight can really help you out. And don't worry about Tru-Glo sights if you decide to go that route.Just stick with their higher end sights they will perform very well.As you know, you can also purchase just the pins, theyshould fit most sights on the market that share the same style sight pin set up(Fiber optic posts)

For$20.00 they are not a bad investment, because they will work just like the other pins in the day light yet may just give you that slightly brighterpin when you need it. Do they shine like flashlights, no butthey are bright enough to see through your peep even in pitch black and that's all you can ask for.
