As I am suffering from an age induced eyesight malfunction, I've found using a pin scope a little tricky.
I have read some very favourable articles on red dot holographic scopes on bows. This has the advantage of getting rid of the peep sight on the string. If anyone has ever had the bit of rubber tube that aligns the peep snap and smack you between the eyes you'll know what I mean.
I have a red dot sight with a x3 magnification lens built in however, no means to attach it to my bow and allow for enough elevation adjustment as it is primarily a rifle scope. Now I know you lucky people over in the USA are a lot further down the technology path than us Brits. Any suggestions?
