Adjustment Patch for Thermal Scope

Specifically designed for adjusting thermal vision rifle scopes, Januel thermal patches work upon contact with ambient air. Once removed from its packaging, the patch takes 3 to 4 minutes to reach a temperature of 38°C. Placed at the center of a standard target, the heat emitted by the patch allows for easy and optimal adjustment of your thermal imaging optics. Its 5cm diameter is perfect for a 100m adjustment.
