Pictured is a Cosmo 600, perfect working condition. As can be seen in the photos, it's got a few scratches. Works well at 600' line of sight, but with bodies it does get shorter. We are missing the articulating arm with crab clamp and the extra d-tap to lemo cable, but including an AC lemo power cable. Comes in handy when at a location with power. True zero delay wireless video for focus pulling, this is the cheapest option before getting into Teradeks. Only reason I'm moving on is to upgrade to a Teradek with longer range. It's been insanely good for me and my team.
