I recently purchased Tobi ET5 and it seems as good as or better than trackir, for me. I love not having to wear the clip, I usually turn off eye tracking and the head tracking seems to work great.
But I do have one issue that I can't resolve. Just wondering if you're having any issues with Toby tracker using any of the HMCS in any of the supported airframes. I've been flying the A10 C2 and when using the HMCS and the head tracking doesn't seem to line up with my HMCS cursor. I'm having the strain my head to get the targeting cursor on what I'm wanting to mark.
Thoughts?
