Nock-to-peep Distance

[Panserborn]

Hi all

Just wondering what nock-to-peep distance other compound shooters use? I know mine is wayyyy to short (about 3.5"). Is there a rule of thumb for this distance? I know ya have to shoot using whatever position feels right but I've been told that my nock/peep distance is so bad that its whacking the timing out. Using an UltraElite (pretty new), and sure enough, the timing is out!

Not a Compound expert but I know a bit. I cant see how peep position could put out the timeing. Its just put in the string. Personally it is just feel. If your anchor is solid on your cheek and comfortable the peep should be some where that allows easy alignment through all the distances. Personally its a trial and error thing for me. I would draw the bow. Get a point marked on the string where the peep needed to be and instal it. Then move it as required.

I don't know if there is a definitive answer, I 'm not aware of timing being affected by moving the peep, I had mine adjusted whilst in the shop and they didn't appear to adust the timing after adjusting the peep height. (having said that i was mostly looking at the shinyness of the new bow rather than paying attention to the tech stuff....)
I can't think of a reason whislt it would effect the timing, I just has it put where if felt comfortable, given that everyones faces are different sizes and shapes.

I agree. The height should be purely to do with confort of aiming. If you draw the bow, have someone mark the string where your eyeline is and that would be a sensible starting point. There is no reason for peep position to affect timing, it is merely a rear sight.

For myself, I draw almost as using my re-curve. Draw, find a comfortable anchor point. Then move the peep up and down till It is central with the sight when I am in a good anchor position.

Thanks all.

If the peep is okay, I'm thinking now that the nock maybe too high. On closer inspection of the bow, the arrow is pointing slightly down and the launcher is positioning it slightly above the "equator" of the button hole. Maybe its that that is putting out the timing. I was told by evenyone that "UltraElites never lose timing". This sounds too good to be true, but I didn't think it would lose the timing this quick, its only about 4 months old!

If you cable an UltraElite with Dacron, I guarantee you it'll lose it's timing.

Equally, if you use brand new stock strings you should expect them to stretch a bit to start and if you're not aware of that you'll be surprised by it...

Saying that "the peep has caused the timing to change" is much like saying which wrist I wear my watch on determines whether the tides go in or out. Two distinct things that are related in only the vaguest way.

no parameter such as peep hight or nocking point can alter timing! listen to what Tom just wrote
If you have a 3.5 inch peep to nock hight at rest then either you have the smallest face on the planet/ your hand get in the way of your eye at full draw or you cant use a tape measure.
A resting peep to nock hieght of 4 inches is the smallest i have ever come across and that is a girl with a very small head
If you are quoting the measurement at full draw then this is a low peep to nock but not outrageous and you may well be struggling for 90m sightmark. My full draw peep hight is 3.5 inches which equates to a little over 5.75 inches at rest on a 33inch ata bow

1. Remove peep from string.
2. Set arrow rest so arrow is in line with middle of berger hole.
3. Move nocking point on string so arrow is 1mm above 90 deg --this is a starting point.
4. Find a good and repeatable anchor point.
5. Shoot through paper to get the nock height correct (move nock point on string to correct if needed).
6. Draw bow (with arrow fitted) and get someone to mark the string at the point that it looks level with centre of eye.
7. Fit peep (you will need a press ) and have fun getting it to rotate correctly.
8.Check you can see scope correctly at all distances.
9.Adjust peep height as needed.
Remember that after all this is done ANY CHANGE YOU MAKE TO YOUR NOCKING POINT WILL MEAN YOU HAVE TO CHANGE YOUR PEEP HEIGHT!!
Bows will not go out of time by fitting a peep.
Hoyts do go out of time !!

Hope this helps

Pretty sound anvice from Nightimer.

My peep height at rest is 6.25 inches. Don't know what it is at full draw, but I'd bet it's way over 3.5 inches.

Ultraelite's can and do slip out if time, but not by much and by very little indeed if you've got a good (452x or Ultracam) string and cables on the bow. I check my timing about once a month and I reckon I need to give it half a twist or so once a year. New strings and cables at the start of the idoor season (so they have plenty of time to bed-in), and the job's done.
