I think I might be able to run level 4. The Phoenix has equipped on his goggles Low-Light, Vision Magnification, Thermographic, and Smartlink. He's got Flare Compensation, too, but I don't know it that counts. He's also got a handheld sensor outfitted with an Atmospheric Sensor, a Laser Rangefinder, and a Motion Sensor. One of his guns (his new primary) has an Improved Rangefinder mod attached to it, as well. Plus, he's carrying an Emotitoy, which counts as a drone for sensor channel purposes, and it has a Sensor rating of 3...even if you discount the Improved Rangefinder mod, and his Astral Perception (Which he gets being a Magician), if everything on his goggles, his sensor package, and the Emotitoy counts, he's got 10 channels.
