What techniques can help when glassing in rain or fog?

Choosing the Right Equipment

When glassing in adverse weather conditions, the right equipment can make a significant difference. A spotting scope with a strong anti-fog coating can help maintain clear visibility, while a wide-angle lens allows you to scan a larger area in a single glance. Look for a scope with a 20-60x magnification range and a lens diameter of at least 80mm. For instance, the Zeiss 20-60x80 or the Leica Geovid 30-70x85 are excellent options. Additionally, consider using a rain shield or a lens cleaning cloth to prevent rain droplets from forming on the lens.

Scanning Techniques

Maintaining a steady and deliberate pace while scanning the terrain is crucial in rain or fog. Take your time to sweep the area, focusing on the edges and ridges where game animals tend to congregate. Use a smooth, slow motion to scan the terrain, pausing briefly on any promising areas. When scanning, use a “sweep and pause” technique: sweep your scope across the terrain, then pause briefly before moving on to the next area. This technique helps you cover more ground while maintaining awareness of your surroundings. A good rule of thumb is to scan in 50-100 yard increments, pausing for at least 10-15 seconds before moving on.

Lighting Conditions

When glassing in rain or fog, it’s essential to use the right lighting conditions to improve visibility. Early morning and late afternoon are ideal times for glassing, as the soft, diffused light helps reduce glare and improve contrast. Avoid glassing during the middle of the day when the sun is high, as this can create harsh shadows and glare. Use the sun’s position to your advantage by facing into the wind or rain, which will help reduce glare and improve visibility.
