It also says something buy antibiotics online like field 9.3degree - what does that mean?
Reply:
its 7x18mm
7 is the magnification power
18 mm is the lens diameter (the larger the lens, the more light)
the 9.3 degrees is the viewing angle -- basically the higher the angle, the larger field of view.


US $9.95
