To my knowledge in the past, the R 10 tilt compensator simply recorded how far out of plumb the range pole was at the time of measurement. You could observe the number in TBC but couldn't apply any correction. Now it appears an actual correction can be applied. I'm wondering how it determines what direction to apply the correction and how much uncertainty is introduced into the adjusted position? The announcement also states it is a good safety feature because now the surveyor can keep a closer eye on traffic, etc.
Anybody have any experience with this? Could be a good thing if it works.

Not that I own one or have any interaction with it, the link you posted gives you the answer to the question you posed.
100% traceable data: readings from both the tilt and compass sensors are stored with every point and flow through to the office for complete visibility and confidence in the measurement results
When I read your post, it peaked my interest and I thought that the only way it could apply the correction is to have a tilt and compass sensor, which it does. How it works is beyond my pay grade, but it makes sense on the sales brochure.:-)
Great - another error to throw that into the least squares adjustment routine.
I thought Dr.J introduced this in 2011?
Introducing "Lift & Tilt" Survey - Javad
I don't trust nothing I can't see. But I am sure it is a great idea and I am just being a luddite.

Thanks Steve
Somehow I missed the part about the compass.

Seems like a pretty similar concept but I wouldn't want the receiver to start logging a point until I told it to do it. What happens when you are in the lift and tilt mode and happen to bring the rod near vertical while walking to the next real point? Seems like you could end up with a lot of useless clutter to wade through.
Yeah, I thought the same thing, but Javad's doesn't start until it is stationary (no velocity) and plumb, and it waits for a user specified amount of time after that to start (like 3 seconds).
I played around with a Javad Triumph VS with lift and tilt. Before I handled it, I thought L&T was kind of a gimmick, but when I actually used it I was surprised how much I liked it and how much attention I had to pay to my "conventional" RTK setup. Trimble is right, I think it will allow for better "situational awareness" in the field. Results seemed pretty good too. I haven't played with it enough to have more than a general feel for accuracy.
