Best Day Vision and Night Vision in one monocular? (1 Viewer)

Hello, I am new to the forum and don’t know too much about monoculars - sorry about that. I’m looking for recommendations for a VERY GOOD monocular that can be used for both day vision and night vision. The monocular will not be used just for bird watching - so looking for one that is versatile. My budget is TBD so all recommendations are welcome. Thank you!

Hi there and a warm welcome to you from those of us on staff here at BirdForum (y)
We're glad you found us and please join in wherever you like. ;)
 
Night vision viewers use various electronics to either amplify the available light or make light not visible to the human eye visible. Thermal imagers will work fine in day light but the image is massively compromised over what you will see with an actually optical (as opposed to electronic) device. Image intensifier type night vision will not work during the day.

Short wave IR will work in both night and day situations. This is the best way to go if you want a single device. The trouble is that it is still very much only in the military sphere. They aren't actually secret technology but will be multi thousand dollars.
 
What birds are you wanting to view by night - birds in general aren't that active after dusk?

Most night-vision devices are pretty poor optically - they don't need to refine the level of detail birders need and they tend to be relatively low magnification. If you're wanting to observe larger mammals of a night some NV's are okay, but you'd want a decent separate pair of bins for daytime use with birds.
 
I've moved your thread to the Bin section as it will get more exposure there :)

You'll be notified when someone responds :)
 
A night vision monocular with VGA resolution will cost you around $4000. That kind of low res would not be considered acceptable in a toy for daylight use.

I bought one of these and have been very impressed. Cost less than £300 ( $367 ) incl freight.
Optical mag is 8x with 4x digital zoom, Colour vision in daylight, black & white at night.
 
Technology for night vision is radically different than for day vision, so what you described appears impossible. A night vision (thermal) monocular works also at daytime, but image quality is much worse than even cheap binoculars.
 
Hi,

While you are probably correct regarding thermal vision (far infrared), night vision includes low-light and near infrared sensors, which are comparatively cheap.

Of course, just as you pointed out for thermals, even those cheaper night vision devices don't compare well to conventional binoculars for daylight use.

Regards,

Henning
