Had some friends show up for a hunt and got to try out their thermals.
We had my Flir T-70's, Flir RS-64-35mm, and Flir T-50 320 core with 60mm lens.
My friends brought their Armasight 640-42mm Apollo and IR Defense MKII 640-35mm.
Did not have any video cables for the Armasight or IR Defense thermals, but did for my Flirs.
All of the thermal scopes worked great, temps were about 75-80 and humidity was moderate, not a problem.
On the night hunt, the Flir T-50 and Flir RS64-35 scored pork:

Everyone had a great time, all the thermals worked excellent.
We were in very dense Florida scrub uplands with limited sighting range where FOV ruled the night.
Both the IR Defense and the Armasight Apollo were a bit longer range instruments due to the microbolometer pixel/lens configurations and tight to work in our heavily forested wilderness areas, however they both gave excellent image presentation and were manually adjustable for a variety of changing conditions if so desired.
The Apollo was easy to use, lightweight with good build.
The IR Defense was also easy to use, more robust and heavier but seems built like a tank.
It was fun to use all of the gear. My friends were not too educated on their Apollo or MKII so I helped them out to understand the operational aspects of their two thermals as to how to use them properly and the various thermal emissivity issues encountered in the field while hunting.
Neither of them had video output cables for their thermals, but I tried to take a digital night photo though the ocular of the MK II at 175 yards from my backyard log stand out to my game cam tree as a representation to compare to my T-70's (note, photos were not taken side by side under identical conditions as these T-70 pics are older and different ambient temp/humidity).

Enjoyed being able to check out my two friends kits and they are more excited now to use them here on future hunts!
