For those who may not be aware, I have been running the SVM through its paces for the past several weeks, thanks to Victor's humoring me by sending the device over.
Tonight is one of those special NV nights where the just-passed new moon is absent with its local rise not coming for several hours yet, and the sky being partly-to-mostly cloudy.
This time, in addition to comparing it with a PVS-14, I have been checking it out side-by-side with an ACOG TA-11F. The environment is suburbia.
In the back behind our house, where artificial light sources are relatively minimal, the SVM actually performed quite well image quality wise. This is a low contrast environment where the gain of the SVM does not flare the display excessively, but there is just enough ambient light to see; I have finally found a situation where this rare balance is met for the device. The downside is that the refresh rate is herky-jerky, even at the minimum 2x mag, with this otherwise ideal lighting combination; not its slowest, but not at all continuous realtime.
The ACOG is a bit too dark to be considered particularly effective.
The PVS is loving life; lower the gain way down for great contrast.
Next I take them out in front of the house where there are plenty of artificial visible point light sources, but it is towards the dark side overall ambient wise.
The SVM doesn’t do quite so well; what it really hates is high contrast environments, and that is precisely what is being presented. Forget about seeing in shadows within 20-30’ of any light source.
The PVS excels; there is obvious point blooming of bright sources, but one can still see in the shadows. Keeping the gain towards the lower end improves contrast.
The ACOG is optically clearer than either of the other two devices, and presents in color. It can’t see as well in the shadows as the PVS, but can easily do so better than the SVM due to the lack of excessive flaring.
