I have 2 tru glo bow sites. one stinks the other is great. the stinky one is their el-cheapo one with no wrapped fiber optics, think its called a brite site. the other one is a single pin adjustable, you'd swear that thing had batteries. you can see the site pin even when its too dark to see what you're shooting at. think its called the glo-brite. its a few years old tho...
