I have not been able to adjust myself/equipment to comfortably shoot with peep sights, I've tried various bows with different sizes of peep sights but all to no avail. For starters I need a shorter draw length of 27" and most bows are 28" which is part of the problem, but I can't seem to focus on the target. Do any of you BowHunters simply use the fiber optic sights WITHOUT using a peep sight? I'm about to have mine removed just to see what it's like but I'd sure appreciate anyone elses opinion before going to the shop and forking out another $25 bow press fee.[:'(]

It could be that your peep is not in the right place. With your eyes closed draw your bow and make sure your touching all your anchor points. Open your eyes and you should be looking right out your peep. Your peep should not be twisted, it should be open and facing your sights. Also it could be the hole in your peep is just too small.. They make 1/4 inch peeps and that is plenty to see through.. I use a 1/8.
If you can get by a bow shop, you should go in and let them see how you are drawing your bow, that would be the best thing to do. I bet it's just a minor adjustment.
No you don't have to use a peep, however this is also another anchor point. it's best to have three anchor points to keep you shooting consistent.

Could not have beensaid better.....

I also think it's an adjustment problem, that is unless you have major issues with your eyesight. Then it might just be your eyes that are the problem.

Who in the world is charging $25 for installing/removing a peep and getting away with it? My archery shop charges be a buck a pop unless they have to re-tie and that's only 2 additional bucks.

I sometimes use a peep shooting 3D shoots(started back last year), but I prefer to not use a peep in hunting season. I have problems on dark cloudy days or during the last part of legal hunting hours seeing through the peep. Most of my problem is my eyes though. I am left eye dominant shooting right handed and thats not good to begin with.

With a draw length of 27 inches I think it may also be the angle of the peep sight itself. Check out Speciality Archery Hooded Ball peeps. It comes in three different angles. They have a chart to match your draw length and brace height so that the peep hole is perpendicular to your eye at full draw. I would recommend the 1/4aperturefor low light and the 3/16aperturefor day hunting.

Check out Specialty Archery's Super Peep. This is an outstanding peep of machined aluminum. You can purchase screw-in inserts with holes of assorted sizes to adjust to conditions and lighting. I will shoot a small aperture for target and under bright condidions and a larger peep for indoor shoots under poor lighting and hunting. There are also clarifiers available to fit this peep to help define the target, especially when shooting with magnified scopes. Here is a little tip to install the peep without a press. Pick up a pair of large toe nail clippers with smooth,rounded handle. Insert the clipper handle carefully into the strands to separate. Then twist the clipper sideways and insert your peep. Draw your bow to be sure the peep is at the right height and it turns so the peep is square to your pins. If not, take one stand at a time from one side of the peep to the other side taking one strand at a time from each side in the direction you need to square the peep. When at the right height and square to the sight, tie it in with waxed dental floss around the ring of the peep. It will stay in place until you need to remove it for a new string.
