Question to Paralinx Arrow ownersParalinx Arrow

Anyone using Paralinx Arrow with wireless focus? Is it good for a critical focus pulling? Any delay issues? Do you advice to get one for focus pulling?

The Arrow is uncompressed HD with zero latency (literally below 1millisecond). Most of the focus pullers I try to use prefer to be near the camera on set, but if they need to be near the monitor for critical focus or other reasons, I'm generally not concerned about using the wireless in this manner.
The HD quality is sufficient to determine focus well enough through just the image on monitor, and the latency is negligible so the delay is no greater than a wired video feed (considering the LCD monitors all have an inherent delay of a frame or two).

With nearly all HD transmitters I've seen a small but quantifiable loss of sharpness due to the raised noise floor. You can see it on the waveform (where what should be a sharp line becomes a fuzzy line) and it manifests into the image as a slightly softer image. There are times that I have called for focus check on the camera only to follow up with "never mind, it's the transmission". It's usually quite subtle...but then again, so is critical focus.
Yup between that and transmission delay it puts the focus puller at a disadvantage
