You can see better with the naked eye in pitch black than with this device.
I am not sure what type of quality control ATN have, but it must be fairly low standards if this is the type of devices they are manufacturing.
A dog in a dark night is visible from say 10 -20 yards with the naked eye, but use this ATN Viper and all you see is a blur. It couldn't even really define a huge tree from less than 30 yards, all you see is a big blury something in front of you.
The only way to see in the dark with this is to pack it away and use your eyes.
I tested this in various conditions, full moon, no moon, stars, infra red on/off, different batteries and overall result in this is an expensive piece of nothing.
