Seals have access to thermal imaging. (The device used in the movie was actually loaned from the US military forces) And if the SEALS somehow cant get the thermal devices, they still have their IR-(nightvision)googgles. Which work rather similiar ly with Thermal.
IRT Braz. Yes, all light spectrums work similiarly. Using different light specturms added to the live view. If we couldnt see a cloaked Predator with a thermal device, how could a Predator see outside from his own cloak with a thermal devicè?
The modern ones are even clearlier.
Dark Martin,
1. The Thermal vision mode (Seen, in every movie, and in every comic with humans and Predators)
2. The electromagnetic vision mode (AvP- movie and in some comics. Used to see tech and Aliens. Aliens are techno-organic)
3. No, it has never been shown in ANY Predator media, except in the games, which hold no ground in here.
The Predator saw himself with his own thermal vision mode. That's it. We can too.
Still, if we somehow couldnt see the heat leaving Predator's body, we'd still see where the Predator is because the Cloak would hide all heat, leaving a darkest possible spot. (in a thermal imaging)
