Specifications
Waterproof models (Main body):
PROSTAFF 5 Fieldscopes are waterproof, and will suffer no damage to the optical system if submerged or
dropped in water to a maximum depth of 1 meters for up to 10 minutes.
These products offer the following advantages:
• Can be used in conditions of high humidity, dust and rain without risk of damage.
• Nitrogen-filled design makes them resistant to condensation and mold.
Observe the following when using these products:
• As the unit does not have a perfectly sealed structure, it should not be operated nor held in running water.
• Any moisture should be wiped off before adjusting movable parts (focusing knob, eyepiece, etc.) of these
products to prevent damage and for safety reasons.

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.
