Having tried numerous methods from the internet to create a thermal target to zero my Pulsar Thermion XP. I opted to try the Thermbright patches, and I wish I had done it sooner! 1x patch at 100m is clearly visible, even during full daylight, allowing me to zero my rifle with pin point accuracy. Time and money well spent, I wont be using anything else from now on.
Been looking for something to set my thermal sights in during the day these work perfectly
