Re: Armasight Spark CORE Night Vision Monocular
My guess it is a commercial gen 1 unit in a nice housing. I would not spend my money on it and think it is over priced by about double what it is work. A commerercial gen 1 unit is a very poor performer and you will not be happy with it. Do not confuse it with a mil-spec gen 1 unit which usually has 3 gen 1 tubes stacked on top of each other, amplifiying the light from the one in front. The commercial gen 1 has a single tube it in that isn't very good to begin with. There is a reason it retails for $450 while a gen 3 PVS-14 is $3500. The commercial gen 1 I had was barely more effective than my bare eyes when acclimated to the darkness. An IR illuminator is not only needed, but it doesn't do alot for it.
If you want to explore a cheap NV, take a look at the GenX digital monocular which is $150 or so. It performs about the same and is worth the money you pay.
You really need to look at a gen 2 unit to get a usable unit. A gen 1 will allow you to see shapes. A gen 2 unit will allow you see what the shape is. A gen 3 unit will allow you to ID not only what the shape is, but the fine details on it. On a full moon night, a gen 2 unit will perform closely to a gen 3 unit. But when there is no moon or you are in the woods, gen 3 really shines.
