Part2
Here is one where the temps outside are closer to 62 and I was in a large field probably over 200 yards away with a hunting buddy of mine. With some tweaking on the focus this is what I'd see.
Fairly usable but I can tell you from experience on that same evening that even at sub 30yd range the same unit could not see turkey or other large birds in the trees at the same temps no matter how I focused it. It also seemed to be picky on whether the subject was broadside or bladed to you quite more than I thought. This was probably one of the best distant heat sigs I got the whole time I used it, many times like when in the woods behind my buddy it had trouble seeing him in front of me only 20 yards. It also was nearly unable to see my parked car heat from 50yds away when looking through the trees because of the ambient mix the sensor experienced.
In the end I think the Seek is a nice item for certain uses like around the house but the sensor is still a bit small for really good outdoor use ie hunting or scouting and to really get the most/best out of this it seems you need to have a large temp differences like 30-40 outside and looking for person/animal heat signatures. Other devices seem to do this better as I saw on a separate site and write up someone did using these for birding. The ThermApp handily beat the Seek XR for detecting smaller animals especially at distance even in the cold winter.
