Quick Answer
Low power variable optics (LPVOs) are generally designed to withstand extreme weather conditions, but their performance may degrade in extremely low temperatures or high humidity environments.
Weather Resistance
When it comes to LPVOs, weather resistance is crucial for hunting applications. Most modern LPVOs are made with high-quality materials and are designed to operate in a wide range of temperatures. For example, the popular Vortex Optics 1-4x LPVO is rated for operation between -22°F and 122°F (-30°C and 50°C). However, it’s essential to note that extreme temperatures can still affect the optic’s performance, such as decreased brightness or accuracy in extremely cold conditions.
Fogging and Moisture Resistance
LPVOs are also designed to prevent fogging and moisture accumulation, which can be a significant issue in humid environments. Many LPVOs feature nitrogen purging or argon filling to prevent moisture from entering the optic. This process involves removing air from the optic and replacing it with inert gases, which helps to prevent fogging and moisture buildup. For example, the Leupold DeltaPoint Pro 2 MOA LPVO is designed with a nitrogen-filled housing to prevent moisture from entering the optic.
Real-World Testing
In real-world testing, LPVOs have shown to perform well in extreme weather conditions. For example, one study tested the Vortex Optics 1-4x LPVO in a -20°F (-29°C) environment and found that it still performed accurately and consistently. Another study tested the Leupold DeltaPoint Pro 2 MOA LPVO in a 90% humidity environment and found that it remained clear and free of fogging. These results demonstrate that LPVOs can withstand extreme weather conditions and continue to perform accurately.
