This is my first high $$ purchase as Im wanting to do some FT-HFT. I have targets set up on my land at 10, 25, and 35 yds. SO the 10 yd mark was right on and accurate. as I focused on my 25 yd target, the AO read at 35 yes and my 35 yd target was in focus with the AO at 50 yds. This doesn't help with any accuracy in range acquisition. The Athlon rep stated these "are only guidelines and aren't always 100% accurate." What? My $89 UTG Bug Buster is spot on at 10, 25 and 35 yds.
Any insight guys? I also inquired about a side wheel and he referred me to Scopeworks but with the caveat that it would be a custom price and probably would accommodate a tape. I'm thinking Ill only up for the Hawke with a side wheel already installed. Im willing to give up FFP for AO accuracy. Thoughts?

The Athlon rep wasn't wrong, and this isn't a unique issue with the Athlon Argos. There are many scopes out there that don't have 100% accurate markings on AO/side focus. The solution (and something most all FT shooters do anyway) is to create their own tape. You can make your own tape and put it on the side focus knob of your Argos and the issue is fixed for the cost of tape, a marker, and some time. If you need more granularity than the small factory side focus knob can provide, then go ahead and get a sidewheel from ScopeWerks, but you're still going to have to go through the process of making up your own tape.
-
there's also the donuts and pointers that some install instead of the tape (and some of those are 3d printed)
but a roll of tape is cheap, and the time spent ranging and marking means being outside
-
I believe there are few scopes where the parallax is accurate. Neither of my Hawkes were.

I've had at least 10 scopes between $200 - $500, and the PA wasn't accurate on any of them. This is the norm.
You may want to reconsider that Argos BTR for FT. Although it is a very nice clear scope, ranging is very mushy. I found it to not be very accurate, even with a 4"sidewheel and custom tape. I've heard similar things from other FT shooters too. Sorry to bear bad news... :-\

News to me, on all of mine not just air rifle but powder as well they are good. From Tasco to Zeiss I don't think I have one like the OP is talking about....seems lazy to me.
How hard can it be to make one correctly, I think I would refuse the product if it was that out of wack.

My Athlon Talos at 25 yards reads as 17 on the wheel.

Powder Burner scopes are easy, set parallax at 100 yards. Air rife scope not so much.
I bet your PB scopes are not that accurate either, just you are shooting at longer distances where it does not matter.

They are likely a bit more accurate than you think. Measure some of the distances exactly and put the side wheel to that range. Then adjust the eyepeice focus.

Just about the same for my Talos 3-12x40. Seems like it should have more accurate readings.

But did you adjust the focus for your eye?

Yes, did the momentary look at the reticle while pointing at the sky.

I was referring to the focus at the eyepeice end of the scope. I have no idea about looking at the sky.

Once you adjust the diopter to focus the reticle to your eye all parallax calibration is out the window. Generally, the parallax cal. is only good at zero diopter; simple physics common to all scopes.

Was about to type a similar response.
ANY adjustment to the ocular focus changes parallax values too.

Every AO scope I have has that adjustment fully screwed in from the factory. I'm betting most people don't know it's there.

well i hope most know its there LOL otherwise they would all have the most out of focus reticle ever LOL

That's why I brought the thread back to life. Apparently people dont. And it won't be out of focus, the range will be off.

I recently purchased (6 months ago) an Athlon Ares 2.5-15x50 and ive been using the AO to range my targets with fairly good success! Its pretty much spot on to a hundred yards but without a custom wheel anything further is a headache lol.
I was under the impression that AO's were 'supposed' to be fairly accurate at ranging??
Maybe what Tom mentioned could be the culprit? I didnt know that btw... Hmmm.. Learn so.ething new everyday on GTA!

without adjusting the ocular/eyepiece yes most certainly the reticle will be out of focus.
i did not mean that the image in the scope will be out of focus.

So if we need correction while shooting, is it better to leave the diopter focus at zero and wear corrective lenses?
Would the parallax/AO setting be more accurate then?

SET the retical focus to your eye ( Ocular ), paint dot where it ends up so you KNOW the baseline setting ... then do your scope tape on parrilax focus values.

Once again chiming in that EVRY ao scope I've had comes with the diopter adjustment screwed all the way in.

Ed,
Do you wear glasses-contacts? Do you leave the diopter adjustment screwed all the way it?

I don't wear any corrective lenses. I unscrew the diopter till it should be at 0. All the way screwed in is as far in the + as it goes.
-
ed,
the ocular/eyepiece is for focusing the reticle for your eye.
adjust it until the reticle is in sharp focus when quickly glancing through the scope.
(when adjusting,dont look through it for a long time and adjust it,
because your eyes will try to compensate for the reticle being out of focus and it wont end up focused properly)

I concur. Many high end scope only have tick marks without numbers.

Agreed! :-*
But by doing so, it seems you mess up the A/o settings. Wouldn't you be better off using corrective lenses and then having your AO accurate? :-\

Precision in focus/parallax is what really matters; diopter setting does not affect precision. Accuracy is increased by adding your field tested numbers to the wheel or giant wheel if you are serious about parallax ranging.
I have poor reading vision which is easily correct by the diopter. I don't require corrective lenses for other than reading distances. I couldn't imagine shooting with my reading glasses LOL!

Tom,
Most ranges that I know, require some sort of eye protection!
I do not doubt that 4 inch parallax wheel or a nautilus wheel and verified tape would be the most accurate, but absent that;
Wouldn't shooting with corrective lenses and leaving the diopter setting on the scope set to zero, be the most accurate way to use the A/O wheel that comes on most airgun scopes?
If you head is in the right position on your cheek piece, wearing glasses will not interfere with your sight picture.
