Rifle Scopes Does anyone make parallax knobs with yardage markings for NF scopes?

[TimK]

It's my only gripe with my NF scopes. I understand the numbers might not be dead on, but having them would be a whole lot better than the series of unmarked lines they have now. Those are so useless they might as well not be there.

If no one makes such a thing, I guess I'm going to have to do it myself either by marking directly on the knob or by making some sort of label.

They change in size so you know which is which...

Smaller lines are close, big are far.

So they are marked, if you need a reference, a nice silver sharpie does wonders

I understand what their markings indicate and how to use them, they just aren't very useful when shooting at widely varying ranges while on the clock in a comp. I've been using tape and writing on that, but it's far from permanent. I'll try the sharpie trick, I didn't even know they came in silver.

Tim,

If parallax could be eliminated with a constant, we would mark them. But atmospherics alter parallax correction greatly. A 20 degree swing in temperature could alter parallax correction by as much as 400 yards. We set parallax in our temp controlled factory at 70 degrees and 40% humidity. That means on a cold day, you could be grossly off as is the same on a hot summer day.

Also consider that not everyone operates in yards, some utilize the metric system and operate in Meters rather than yards.

A piece of tape that you could temporarily mark is your best bet for any consistent accuracy. I use colored sharpie markers on mine for quick reference. That way they are not married to a specific number and I can create a small cheat sheet to wear in my arm board for a specific shooting event to reference once I establish where I am parallax free for specific ranges.

I'm sorry you find the markings useless, but hopefully my explanation will shed some light as to why we do it that way.

Thanks for the response. I didn't know it could vary that much. I understand why you don't do it, but I'd personally still rather you did. I understand it would be off, but it would be some sort of indication which, in my head, would be better than the lines which I find difficult to see and interpret without breaking position.

On the other hand (now I'm arguing with myself), maybe the fact that they are not there will force me to do what you describe, which is actually what I've been doing but with tape and a pen every event. I've always begrudged you guys for not marking the knob with numbers, maybe I should be thanking you. In light of what you've said, I understand it will be the most accurate method, and that is my goal. I just need to find a clean way to mark the knob that I can see readily when in position with the damn clock ticking.

Thanks again for the response. Just what I was looking for.

Edited to add: This is just one more thing to love about NF, having someone here answering questions directly.

maybe your is different, but on my NSX 8-32 X 56 the marks go from large to small with a little infinity sign (sideways 8) at the end of the small marks .

not saying it's needed and you've gotten good feedback above but I know one wants what one wants. I believe that Kenton industries will make one for you, it's not listed on their site but i'm almost positive they will do it if you call.

I think you're correct... Lowlight probably just misstated. Anyhow, doesn't really matter as we're supposed to focus looking through the scope, not by using the knob anyhow.

To the OP, I say it's more important to learn how to focus properly and get rid of parallax while looking through the scope... than to get a sticker that will be wrong most of the time.
