Yep the Smart Tracer nocks that Mauser mentioned are tops........I wouldn't honestly spend a nickle on Lumenoks after seeing how they perfromed for my buddy Frank. [:'(]

The Tracers were AWESOME. They work 100% won't get knocked off on impact and they blink every few seconds after the first 10. To shut em' off you simply pass them back over the magnet on your bow.
If I decide to use lighted nocks again this season I will look no further than these.
