Thermal Doesn’t Work in Summer? We Tested It.
This video tests the effectiveness of thermal optics during summer conditions, particularly in Finland and Estonia where temperatures reach around 30°C. It demonstrates that while effectiveness is reduced compared to colder months, thermals remain highly useful for detecting heat signatures, especially in dense vegetation or low-light scenarios. The video highlights that movement is the primary giveaway, even with camouflage, and discusses the impact of ambient temperature, sun angle, and surface heat on thermal performance, recommending a combination of thermal and day optics for daytime use.
