my question. Someone on the split finger versus 3 under thread mentioned that they shoot accurately using the 3 under method out to 20 yards then start degrading due to unconscious gapping etc. Can someone please clarify for me how that works....and also clarify for me the affect the two styles have in general on instinctive vs gap shooting?
Just to answer your question without getting side tracked.... Shooting 3 under typically raises your arrow closer to your eye making the gap between the point of your arrow and the location of impact smaller.
Example: with split finger anchored in the same spot as 3 under your "Point on" would be 40-45 or more yards,and the point on gap would be 18" lower than the point of impact. where with 3 under your point on would be 20-25 yards. raising the arrow closer to your eye gives you a smaller gap. on 3 under your point on would only be 4 inches lower for 15-20 yards and still on the body of the target.
the second part of your question is instinctive vs gap. With gap shooting you consciously measure the gap between your arrow point and the impact point. If you hold your point on target and hit dead center at 25 yards and move up to 15 yards, you need to set the gap about 4" lower than what your point on is.... You also need to estimate yardage and set your gap for each distance.
Most Instinctive shooters typically shoot split finger, but not always. some have a 3 under release but a lower anchor point..... The gap method i explained above still exists, only its done on a subconscious level. Instinctive shooter do not consciously measure the gap. they concentrate totally on the spot they want to hit & let their subconscious mind do the calculations for elevation at different yardage. There are instinctive shooters that are incredibly accurate at a wide range of yardages too.
The guys that say they can shoot 3 under using a gap very accurately until long yardage comes into pay. just need to spend more time shooting longer distances and learn to use their gaps and focus on a spot higher that the impact point. The reason this is tough is because once their point on raises above the target completely they can no longer focus on the spot they want to hit and the arrow gap too because there is no gap.
To successfully using a gap system at longer distances, you hold your point on the very top of your target at 30 yards and see how far the arrow drops from the point on. Then you take that gap lets say it's 12". look at your target and pick a spot above the bulls eye 12" and hold your point on it. the arrow drops right into the bulls eye.
when you move back to 40,50, and further yardage you need to adjust the point on further above the target at each distance as you calculate the yardage.....
A lot of guys that shoot "Split vision" with split finger, pretty much focus on their spot from 15 - 30 yards and don't consciously use a gap. then become more conscious of the arrow point as it comes into view and tightens their gap. As they get closer to their point on the arrow tip is more visible as they get out there around 40-50 yards..... hope that helps...
