thanks for the input guys. I used a Lumenock for my compound arrows last year and loved, found it to be very advantageous in a couple instances. My dad decided last year that he wanted some too, after he missed two different does out of the same stand at 30yrds and it absolutely baffled him as if he shot high or low. Plus he his handicapped and Im normally the one searching for his bolts...so that lil light on his bolts will help the both of us.
