Despite being large and old, the 1PN34 and 1PN58
have proven to be a great additions to the collection
and perform very well in the field. I've used both to
hog hunt here in Texas on several occasions and
they've been very useful in all but the darkest
conditions. While cumbersome they are both effective
from a fixed position and have been a lot of fun to
use. While there are definitely more modern NV optics
out there I have been happy with both.
1PN34 and 1PN58 have been seen in the recent
2014-2015 Ukrainian-Russian conflict
1PN58 shown here without the lense cover

1PN58 on 1988 AKS-74N
1PN34 (Top) and 1PN58 (Bottom). Lense cap on both is removed for nighttime use by twisting clockwise and pulling out. The cap has a diopter that can be clicked incrementally to increase daylight visibility but the cutoff mechanism will immediately turn the optic off if too much light comes in. Do not take the cap off during the day or you risk burning the optic out.
Not the best picture due to the daylight filter
being on. View through the 1PN34 is much better at
night without the filter cap on.
