Paper makes the PVS24 look an under achiever lots of things look better on paper,One example is when we took Guns off fighters in Nam,That old paper lost alot of Hi tech Fighter to Low tech migs when the Fight was belt Bucle close..I think some paper is better left on the desk and use what gets the Job done for the task. </div></div>
Sorry ASM1, can't agree. Paper is just a way to demonstrate and illustrate an argument. it's a shame that sometimes when people who don't know how to interpret paper correctly get involved that that usually ends up badly, but no amount of blind faith is going to address a shortfall on paper.
Under 50 yards, I would not want a PVS-24. Most dayscopes have a FOV of somewhere around 3 degrees. Not much. Your average monocular has a FOV of 40 degress. Now tell me honestly, at under 50m, blind except for your NOD, whether you'd prefer a monocular and a laser or a PVS-24 with an effective FOV of 3 to 5 degrees?
Or if you prefer mounted, a PVS-14 behind a reflex sight still giving you 40 degrees of sight instead of 3 degrees?
On paper, I really got to say that your argument doesn't make much sense. Of course, I'm not a soldier anymore and for all I know, maybe looking down a narrow pipe where you can't see anything really is better now than a wider field-of-vision but it certainly wasn't back when I tried it.
And there's your problem. Mismatching components really screws things up and it's easier to sort out on paper, though as you've probably encountered, you are expected to commit most of that paper to memory, but it's still paper or at least was. Once you sort the basic stuff out, then figure out the field side. No sense doing something mismatched like putting an 8x scope behind a PVS-24 is there?
Most ACOG's have a wider FOV than typical riflescopes. A 3x, 3.5x and 4x have 11, 16 and 20 degrees FOV, respectively based on published data.( assuming you're close enough to it ).
A PVS-24 has a lens FOV of 18.6 degrees, so assuming everything is optimal, it's pretty well suited to the 3.5x and 4x ACOG.
Now go and stick your typical 6x dayscope into the same ACOG? You're now at 3 degrees, so you've limited your FOV which is tactically undesirable,
worse, you've just lost 83% of your tube resolution which means the fight had better be under 50m and with a full moon or you're likely to be in serious trouble - assuming you can even find the enemy since you now have to scan the entire horizon like a turret to spot anything.
The PVS-24 is a good scope and you're absolutely right - pick the right tool for the job. But unless you're using an ACOG, then the PVS-24 is not the right tool for the job and we can see that pretty quickly on paper.
So if you're using a dayscope, a PVS-22 will give you 20% more FOV and resolution not to mention better system gain. The PVS-27 will nearly double everything.
If you're using a clip-on with a normal telescopic sight of high zoom, choose wisely. Or go dedicated...
And there's nothing wrong with using paper or tables to help you get a little closer to optimal before you let your experience and determination do the fine tuning.
Because on paper, it never made sense to get rid of guns from planes... Except from a commercial perspective.
