I went looking for a "poorman's" NV solution last year and found that most Gen1 monoculars were very poor, almost unusable without a 1/2-full moon.
I was trying out a Gen1 Yukon against a PVS14 to see the separation between the two and if some NV was better then none. Most will tell you that it's Gen2+ - Gen3 or nothing.
I disagree.
There is no doubt that the PVS14 is very nice and auto-gating is the way to go, but $3000+ is a steep price tag unless you have tons of money and all your preps are set already.
The Gen1 monoculars I tried were barely better than adjusted eyes and without an IR source, worthless unless there is 3/4-full moon out.
I ended up going with a NV scope that had gotten good reviews online (the
Yukon NVRS Tactical 2.5 x 50 Generation 1 Night Vision Riflescope) and am pleased with it. The ability to focus is HUGE on a scope and most Gen1 models do not allow this, or do not do so as easily as this model. It gathers light well and the IR is a good beam.
Wanting something I could wear on a helmet, I saw the
Armasight SPARK monocular come out and the initial video from it looked like Gen2 (which it has specs for even though it's Gen1) and so I purchased it and a helmet setup, only to learn that without an IR laser using it to shoot while mounted to a helmet is NOT going to happen.
The SPARK is a great unit for the price though and at 1/2 the cost of a low end Gen2 monocular, it fits the prepper's niche well. You can't go wrong buying top shelf in NV, but do you really need it?
In my case I've settled on the SPARK and will be using it passively ONLY while taking listening breaks or while in an OP.
The use of an IR source is the equivalent of using white light and with NV so cheap these days, I expect more than myself to have it. I think one is better served using natural adjusted eyes for movement at night 90% of the time and just as I would not allow WL ad's while patrolling, it is a big risk to think that an IR ad is somehow acceptable.
The odds are on your side until they are not!
I've made a few videos (
http://www.youtube.com/user/dvcprepper1) that don't really do the two devices justice, but give a good comparison between the two. The 1x SPARK is sharper and brighter by 30% if I had to guess. The scope on a suppressed 300 Whisper is one bad ass OP rifle though.
