The two point sight- how and why it works
The idea of using two solid sights on a bow is not new. The patent office has many examples. What is new is their fairly wide spread use as archers begin to realize their many advantages over sights that float in the bow string and require the archer to assume a correct form or posture with each shot.
If we consider the bow drawn to full draw, minus the archer, that is in a mechanical drawing device with proper support at the riser handle the arrow will travel down range in a fairly uniform manner assuming proper bow tune, arrow spine, etc. If we then introduce a two point sight on the riser we can then adjust the sighting reference front and rear to make the sighting reference match the impact point.
It can also be shown that this can be accomplished with one person drawing the bow, being careful not to torque or twist the riser and then with bow held out enough to allow another person to do the sighting and direct the person who has drawn the bow where to move to achive the desired point of impact, the shot can be made with no sighting input from drawer of the bow.
The simple truth is that if the bow is drawn straight back the sight will act as the only reference necessary and no particular form is needed. Most experienced archers have a difficult time with this principle. They have had anchor point , anchor point, anchor point preached as the gospel to them.
If we look at a firearm we can be assured that if the firearm is sighted properly the bullet goes where the sights look. We would not remove the rear sight from a firearm, or let it float, and expect it to perform properly. A bow is no different. By using a front & rear sight we can get excellent performance without perfect form .
This is great news for the hunter. If he has to shoot from odd positions, he need only be careful not to twist the bow, line up the sights and shoot. The bow is the same as the firearm. THE ARROW GOES WHERE THE SIGHTS ARE ALIGNED
The gun type sight is gaining popularity as archers discover all of it’s advantages.
