6 Moon nocks with matched weight (Three Green and Three Red) and two Hunting circuits. I used these with Gold Tip Laser III's but with the O-RINGS they will fit several bolts. Go to firenock.com and make sure they fit your bolts.The batteries are BL type. They work great but I'm using these from a SZ380 and don't want to use the battery shock cap. $30 shipped Paypal or Money Order. I tested both circuits and they work great.
