The sight pins on my Copper John Hunter Pro are too small for my old eyes. I emailed Copper John about the difficulty and their response was nothing less than OUTSTANDING!
They are sending me the fiber optic material to custom make my own pins (the option that I chose) and larger sighting dots. They have also givem me the option to send my pins in and they would do it for me. Now that is support that we get only from the companies with the highest intergrity. They are more than worth your consideration.
That said I am trying to find someone on the forum that has experience working with fiber optic material that would be willing to share their tips and information.
Thanks heaps.
