Choosing the right thermal view when conditions change.
Early in the night, the ground can still be warm. Trees and rocks can hold heat from the day’s sun. Add some humidity, a blanket of fog, or unexpected snow squall, and suddenly the view through a thermal device can start looking a little muddy. Animals don’t pop. Details get softer. Brush and background cover start to blend.
The Veil™ 400 Thermal Monocular gives you three thermal viewing modes — Balanced, Contrast, and Brush — for moments like that. Each is designed to handle common hunting conditions that affect thermal visibility and target detection. Here’s how they work:
BALANCED MODE
Use Balanced for fair weather, balanced backgrounds, and open ground.
Balanced is your baseline thermal viewing mode. It’s the one you’ll run most often, designed for nights when temperatures separate cleanly and humidity’s normal. It’s good in early evening when the ground has cooled evenly and heat signatures from everything in your view stand apart.
In open ground or when scanning mixed cover, Balanced Mode preserves natural thermal gradients and softer edge transitions. That means animals look like animals — not glowing cutouts. You can see shape, movement, and surroundings without the background features cluttering the scene.
CONTRAST MODE
Use Contrast for backlit conditions, targets in shadows, or behind foliage.
Some conditions flatten everything. Warm ground. Warm trees. Warm brush. Add an animal standing in front of a warm hillside and suddenly there’s not much separation to work with. Edges soften. Targets details can appear to bleed a little more into the scene.
Contrast Mode is made for those moments. It amps up heat separation between warm and cool areas. That means targets tucked behind foliage or backlit by warm terrain become easier to spot.
BRUSH MODE
Use Brush for dense cover, humid nights, subtle heat signatures hidden in brush.
Brush Mode is for the toughest thermal conditions. Heavy vegetation. Fog or snow in the air. Nights when humidity hangs low and heat signatures barely seem to separate from their surroundings.
This mode emphasizes fine thermal differences and sharper edges. It calms that extra visual “noise,” helping you seen through the clutter that otherwise make traces of heat harder to identify.
