Congratulations BRB!!! The XQ38 is the bomb! The quality of your thermal imager is outstanding. It will open up your world as there no longer are limitations to doing work in the dark and night time is now your friend.
On bigfoot TV shows, they seem to always use red hot or a color theme. In my opinion, it is more colorful for TV purposes but not for visual detail. I toggle between white hot and black hot and prefer the black hot for definition.
Did you get a spare battery? They're not cheap...$80, or so, if memory serves me.
I would highly recommend accessing "nightvisionforumuk.com" for information. It is the most informative about thermal imagers, especially Pulsar, on the internet. You have to register an account first before you can view posts. Bruce, aka "phoenix", on that forum is the Einstein of Pulsars.
