Creep Tuning?Contributors to this thread:
Lately I’ve been shooting a lot and on certain nights my POI at 50-80yds is about 3-4 inches low, obviously theirs times the pin dips and I know I broke a low shot but when I’m shooting good and holding we’ll my arrow groups are tight but I still get a low impact, I’ve heard Ulmer speak of creep tuning so if a guy is hard on the stops shooting a strong shot POI is same as if your weak in the valley, I don’t know the cause and effect of either but it seems like when I’m shooting a strong shot I hit low and if I’m lazy on the back wall I’m in the middle, can anyone elaborate on this.
What type of cam system are you shooting?
Hoyt Ventum pro with the new binary
You can give it a try by speeding up the bottom cam a bit. By definition the cams are slaved together but you can affect nock travel by "creep tuning."
Your anchor could also be floating around group to group which would explain the high and low.
How much you heel the grip or not affects vertical POI. Also whether you are rigid in the bow elbow or slightly bent has quite an effect for me.
I was at a local pub last week when a creep wanted to follow the cute bartender out to her car.
He had a different tune after I was done with him.
One thing I've really been "feeling" lately is hand pressure/ high grip vs low grip. I graph more or less the same spot on the bow but at times I notice I am getting more pressure on th top of my grip vs bottom and vice versa. I'll still hit solid groups doing only one of those but my poi changes an inch or two lower/ higher. And that's at 20-40 yards. Give it a feel with your palm, purposely shoot some shots with the heel vs more of your thumb web
Thanks for the info guys I shot again this evening tried a few things and mostly still printed low 1 turn on the gang adjust of my black gold and I’m back in the middle at 60 and basically little effect at 20 , I’m always hesitant to make sight adjustments at first cuz I have bad days of course the inconsistencies just worry a guy more then anything for that 1 arrow you may get to release on something with a heartbeat I’m not done tinkering and always looking to improve my game, thanks : Jim
It could also be you are dropping out of your peep. If you are setting your peep at 20 yards it makes it more difficult to stay in the center of your peep at longer distances. If you aren’t seeing a perfect eclipse at all times you will drop low.
