Re: Night vision rated for high power??
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: drwoodyash</div><div class="ubbcode-body">New to forum. Trying to find a night vision device that would hold up in front of a high powered scope on a 300 ultra mag or at least a 260. I have read all the posts and seems the common units around $4,000 AREN'T RATED FOR anything more than a 223. I'm new to long range shooting, but plan to learn on hogs at night and deer in daytime as well as paper . Power line shooting up to 600-700 yds. I have an AR, but want to learn on a more powerful cartridge. Scope is a NF 5x22. Anything out there under $10,000? Thanks for your help.

The Raptor 4x, Raptor 6x, D760, PVS-22, and PVS-27 can all handle recoil from long distance rifle cartridges such as .300 WIN MAG, .338 LAPUA MAG, and above. If considering a Raptor, be certain to acquire a more recently manufactured unit. I've experienced problems with earlier Raptor models not holding zero on .338 LM, but more recently mfg. units seem to have the problem fixed. All of the dedicated and clip-on scopes listed in the first sentence are less than $10K, except for the PVS-27 which can be had for a grand or two more.
The PVS-22 and -27 are "clip-on" scopes that can be used in front of your fixed or variable power day scope (objective lens). The Raptor 4x and 6x are dedicated, fixed-power NV scopes with built-in, illuminated, aiming reticles.
No matter what you're shooting, it is important to be able to positively identify your targets and their discriminating details. Under low light conditions, the ability to resolve details on distant targets becomes more challenging for various reasons pertaining to the physics of scope lens systems. Specifically, as the magnification goes up, the amount of light transmitted through the lens system decreases, giving a darker and lower resolution image. The PVS-22 gives optimum resolution up to 6x - 8x if used with a day scope with high light transmission. The PVS-27 gives optimum resolution up to 10x - 12x if used with a day scope with high light transmission.
In my personal opinion, 6x magnification is optimum for *daytime* shooting out to 300 yards. In my experience, with 6x -- with the "best glass" and GEN 3 light intensification under "no moon or heavy cloud cover," night time viewing conditions, and without additional illumination -- the equivalent subjective resolution is cut to about 1/2 that distance (150 yards).
