how much light is available, and the gain of the product. A long,
powerful lens will increase magnification, but as mentioned
above will not transfer light well. In conditions with less light,
more gain is required to view objects farther away so using a
high-speed lens with less magnification will allow more light to
be captured and will increase the product’s range abilities.
Generally most users don’t need long-range capabilities in
their products and are satisfied with 1x to 3x the normal image
size. For example, a Famous Trails product made for viewing
objects at a fairly close range 1x image size. This makes it easy
for the user to view the subject without becoming disoriented.
IMAGE QUALITY— The best image to have is one with little
distortion, high definition and excellent resolution. The Famous
Trails device displays a green monochrome image that is clearest
in the center, with blurring towards the edges. The human eye is
able to perceive contrasts in green more easily than in other colors
so this further enhances image quality. With less distortion you’ll
see a flatter, less rounded view with a higher definition.
Additionally the contrasts will enable you to perceive dark objects
against darker backgrounds and the increased resolution will allow
you to see identifying details clearly instead of mere shapes.
Buying a Famous Trails
®
Product
Before purchasing a Famous Trails product, think about how
you want to use it and select the device that best matches that
use. A scope with moderate gain and a short lens with a 1x
magnification would be appropriate for populated areas such as a
housing complex. If you are using the scope in a forest with little
light, increased gain would enable you to see more clearly and a
longer lens would allow for viewing at a greater distance. Inside
a building or warehouse a user would want to use an infrared
illuminator and would probably not need long-range capabilities.
There are other considerations to be made before choosing
your Famous Trails product:
