You're right with your statements ninepointer. My wrong! Parallex was most likely not the problem. I didn't initially see his "10pt 3x" as a Tenpoint crossbow scope.
My point on parallex was to highlight that scopes suited for rifles(usually parallax free at 100 yards) are designed to be used at longer distances and are lousy at at 10 yard use and could have caused a blury view. Although parallex isn't directly related to bluriness or focusing, parallex could be the end result of using a scope designed for a different distance use. A parallex adjustable scope with a front adjustable lens, does make the view sharper by turning the lens to where the target is sharpest at given ranges/distances. Many better high power scopes have a forward adjustable lens for these varying distances. (My dad has an old Weaver steel variable scope 3 x 9 with this parallex/focus ring on his .300 Win. mag. It's a super sharp scope that can be adjusted down to 50 yards on the dial ring. )
"To use a parallax ring, which many scope manufacturers call an AO (for adjustable objective) ring, turn the ring until the target appears sharp in the scope. The true distance to the target may not always agree with the numbers etched on the parallax ring of the scope, but the scope is adjusted when the image is at its sharpest."
I agree though, probably "too much power or poor light gathering or both".
You would think that Tenpoint would have looked at this when they started selling this scope. Nice looking product anyway.
bstout wrote:Woodsman is correct. Parallax also has to do with the scopes ability to focus both the crosshairs and the target simultaneously at a given distance. Rifle scopes are all 75 yards or more. They work poorly at close range for this reason. My Simmons crossbow scope has adjustable parallax from 8 yards out to infinity. This is a wonderful option.
It also has BIG FAT crosshairs that are a snap to find fast in low light.

bstout & Woodsman,
Since my my knowledge of parallax comes from rifles (at rifle distances) I have never experienced the problem of simultaneous focusing. Thanks for teaching me something me something that I did not know about parallax .

Some scopes are just better in low light than others. I have a bushnell an older Weaver a Redfield and a Leupold. The bushnell and Weaver are about the same with the edge a little toward the weaver, but at the same time in the late afternoon set on the same magnification setting the Redfield is much brighter and clearer. My Leupold is the best of all four. The difference between the Leupold and the Bushnell is stagering.

A man who makes no mistakes usually doesn't make anything at all.
I've used my Exocet since '97 and have never mounted a scope on it, and I won't in the future. At least not until such time that my vision starts to fail. I prefer the open peep sights. I limit my shots to 20-25 yds or under, no exceptions, and have always gotten my share of deer.
On another note, are you sure the AO (adjustable objective) on that 3-9X Weaver adjusts the parallax too? I'm betting it only changes the focus, not the point of impact like a parallax adjustment would. I used to have one years ago on a .222 Rem.

Gary,
I like the peep & fiber optic front sight, but the fiber optic becomes fuzzier each year I went to a 2x red-dot for that reason only. The Excal scopes are good, but they have too many yardage marks to suit me. I have missed a couple deer simply because I used the wrong yardage mark. The 20 yard crosshair held on the vitals of a 30 yard deer puts the arrow just under it's belly
Hi Wabi. I'm 51, and my eyes are starting to slip a bit. No problems yet, but it probably won't be too long.
Which kind of eye deficiency is the worst for open sights with a bow...being near sighted, or far sighted? I'm getting far sighted,
(I think) I can see distance fine, but up close for reading is what I'll be dealing with.
the problem had nothing to do w/ the magnification at close range. i could not even see a big tree thru the scope at 30 yards. there was plenty of shooting light left. anyways, i put a REDFIELD wide angle 2 x 7 scope and promptly shot 2 does yesterday evening(although not at last light). the redfield simply draws more light in at dusk. my point is why have a $60 scope on a $900 xbow? it does nto make sense to me. the xbow came w/ a red dot zero magnification scope. i then purchased a 10 pt 3x X 33mm. i dont know about excaliburs scope--maybee that one will be next.
To answer Gary's question, my dad's weaver does indeed adjust parallex. It is similar to the scope shown at the link below. Parallax, from what I can understand from the following, is related to the focusing of the front objective.

Hi Gary: Long time no print. You lost me on this one. The AO (adjustable objective) would only change the magnification (3X to 9X) and not the focus is my understanding. I believe only the eye piece would adjust focus. The parallax on a rifle scope or most scopes for that matter is fixed for a given distance (75 or more yards) at the factory and stays put.
With my 4X Simmons Crossbow scope the adjustable objective does not change magnification (it is fixed at 4 X) but does adjust the parallax setting allowing you to focus both the crosshairs and the target at the same time for whatever distance you set it at (mine is set for 15 yards).
I have never noticed if this parallax adjustment alters the point of impact or not. I have asked that question on this forum before about the principles of operation for the Excalibur VariZone scope and no one knew the answer. Maybe you can tell us about the scope you use to use on your 222 in greater detail? That would give a better understanding being a long distance weapon to the priciples involved. The same thing would happen up close just not as noticeable or exaggerated.

Howdy Bob! I guess I'm like a migratory bird, I only turn up here in the fall when deer season comes around.
The Weaver scope I had was pretty old, and I kinda doubt it had adjustable parallax. I think the AO (the big end of the scope) was only for focus. It had range markings, and they had to be set correctly or the image was blurry.
I thought that parallax was the difference between the line of sight of the scope, and the line of sight if you were looking through the bore with the bolt removed. These two line converge somewhere out there, but only cross in exactly one place. From the link Woodsman posted, parallax seems to be something different that what I thought.
HaHa! All those knobs and numbers stir my brain cells up too much. Guess that's why I like peep sights!
It is really simple. The crosshair is a constant size in the scope, but by varying the scopes power you change the image size relative to the crosshair. We've marked the adjustment ring on the scope with the velocity that matches the correct spacing on the range markers to comp the arrows trajectory. It works great!
