The  Navigator  II  detects  differences  in  heat  and  displays  them  as  black  and 
white	TV	video.	 It	may	 look	 like	a	black	 and	white	 version	 of	what	 your	eyes	
see,  but  it’s  not.  The  Navigator  II  sees  heat,  not  light.  The  sooner  you  can 
understand and get comfortable with that difference, the more you will enjoy 
this incredible technology.

Weather
Environmental conditions, including time of day, humidity, and precipitation, 
will  affect  image  quality  and  contrast.  Fog,  smog  and  rain  will  decrease  the 
range at which you can detect a given target. After sunset, objects warmed by 
the sun during the day will radiate their stored heat for several hours. Early in 
the morning, many of these objects will appear cooler than their surroundings, 
so be sure to look for subtle temperature differences in the scene, not just hot...

knowing  anything  in  this  section.  But, if  you would  like  to  learn  more about 
thermal imaging – how it was discovered and developed – read on.
