I have been thinking about trying them out. If the cost of them aint to high they would save me money by finding all my arrows and xbow bolts. with the cost of the shafts and broadheads can be pricey.
Initial cost is kind of high IMO but the savings in finding otherwise lost arrows is well worth the cost. I use crossbow shooting 340 fps and have had no problems watching the arrow flight and pass through.
I started using Luminocks because I read nockturnals do not hold up well. It was said that they came apart when shot leading to a dry fire - can not afford that - too dangerous.
Still using Luminocks as they work as described.
