No, as you suggested, it is better to sight in at 20 yards, then at 30 by turning the speed ring only, 40 with speed ring only and the 50 by speed ring only. The go back and reconfirm 10, 30, and 40. Don't worry about 10 too much. For me, 10 is about minute of deer accurate!

Thanks a lot guys. I've been using a Leupold Gilmore red dot and guessestimating hold over from sight in for longer distances Real pain in the butt. I'v heard about the Lumizone but not seen one Where I live there is no place availabe that sells the stuff a guy needs. I have to order from catalogs or off the internet.Based on what you peole have said I am going to buy a Lumizone scope. I shoot a Hortom CB and use it for deer huntintg as I can't hold a regular bow. Sounds like this scope will be just the thing

Thanks again!

Well, I forget the name of the retailer, but you can get the lumizone for about $30 cheaper than Cabelas. I found this cheaper source by going to Google and searching for it under shopping.
