With the Night Detective Piezo Night Vision Monocular, your covert nighttime excursion to the cookie-jar
...
can be executed without signaling attention from those who might frown upon your nocturnal snack. Perhaps you've been meaning to find out who (or what) has been wreaking havoc in your garden after midnight? With the Piezo night vision monocular, you can take away the cloak of darkness from those lurking in the shadows. You will see, without being seen! This clever NVD opens up new possibilities with the ability to observe and navigate through your surroundings under twilight, or starlight conditions. When total darkness prevails, the built in IR lamp provides ample auxiliary illumination so you can clearly visualize all that goes bump in the night. The light intensifying abilities of the Piezo Night 2x are provided by a respectable first generation intensifying tube. First generation NVDs are a cost effective night vision option for the enthusiast, or casual user. They provide well defined imaging with excellent levels of center-weighted resolution. With supplementary IR illumination, they deliver fabulous no-light imaging performance. Additionally, the Piezo monocular needs no batteries; its light intensifying circuits are powered by a hand-operated piezoelectric mechanism. Simply squeezing the lever on the top of the monocular turns night into day, giving you the power of sight at night. There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies. Many different formulas are used to determine the statistic of maximum viewing range and the method of calculation varies by manufacturer. The important factors to consider when evaluating any night vision device are the intensifier tube's generation, s/n ratio, level of magnification, specified resolution, along with the clarity & light transmission efficiency of the optical system. All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
