so I am new to night vision. It's always been limited and restricted. Until recently haven't much to shoot at. Past couple of years we've had a population explosion in coyotes. Things are still quite restricted. We can use calls and lights however rimfire are the only rifles allowed 22cal and under. I know absolutely nothing about IR or thermal other than it can be extremely expensive. I'm thinking IR to start out with mostly because it is cheaper and budget is a major factor for me. I would say that I could go up about 750 on price. Any suggestions keep in mind I know little to nothing on this subject.

The link below gives a pretty good explanation of the differences of SWIR, MWIR, LWIR.
You will NOT find any decent thermal sights in the $800.00 range unless you find someone who has one they are just trying to get rid of... not common. There are some quite satisfactory active IR (generally SWIR) sights out there in your price range. I have two ATN sights... the X-Sight II, active IR, and the ThOR LT, passive IR. Detection, recognition, and identification ranges are not bad for the prices. For the X-Sight II, I use the ATN 850mW long range illuminator which is very good out to about 300-350 meters. The ThOR LT has about the same detection range(ID range is about half that in good conditions). I've got over 500 hours on the LT now and for short range varmint/pest extermination it is quite good... price under $1200.00, I think. I've found it to be a very good deal for the price. The thing to remember using NV and thermal devices is... Identification is the KEY factor. There are 3 primary factors: Detection (D) (know there is something (objects of interest) out there), Recognition (R) (classify differences between targets and non-targets), Identification (I) (clearly determine that the object of interest is an intended target) . Differing atmospheric conditions, based upon the sensor in use, will have different effects on D, R, I. DRI is not a constant. Higher cost/quality sensors can produce dramatic improvements in DRI, but dramatic improvements create geometric increases in cost. Research as much as you can, try to get some "hands on" experience with a few, pick one that fits your performance requirements vs price. Low light/no light vision rifle optics are very personal. Don't let someone else's thoughts on the matter determine your choice. Could well not be the right one.

Opinion,untempered by fact,is ignorance.
There are some who do not fear death... for they are more afraid of not really living |
