* The number calculated by the formula [tan ω ' = Γ x tan ω ]: Apparent field of view: 2 ω ', Magnification: Γ , Real field of view: 2 ω
** At lowest magnification.
Water-resistant models (Eyepiece lens with main body.):
In normal use, there will be no water penetration (As tested by water equivalent to more than 1mm per minute,
falling from a height of more than 200mm for a duration of 10 minutes).
Drops of water and other types of moisture will not damage the Fieldscope, but be sure to observe the
following during use:
1. The unit is neither waterproof nor airtight, so it should not be held under running water or used in rainy
conditions.
2. Movable parts (focusing knob, eyepiece, etc.) of the Fieldscope should not be adjusted in wet conditions. If
you notice moisture has accumulated on the product’s surface, gently wipe it off immediately.
