Was helping a colleague lay out a large facility with the construction crews right behind. Our part was to layout building pads and piers, the piers are a GPS project but the building corners are strictly for the robot.
I'm not expert with the T6 like some of my guys are, but I can use it, one routine is to have it turn to a point when it gets lost. The T6 was sitting on control for the larger project and on a baseline set up grid north by my colleague for the main site facilities area.
The control is typical; on a modified surface, in this case based on UTM and they sent him coordinates in feet and inches for the new buildings and he put them back on the project control. New buildings are based on 100' elevation at the SW corner of the one existing building.
So as we are setting out pad corners and offsets the robot would lose lock, a truck parking on line or such. I would have it turn to a point I had just shot and find me again. Working well, then when moving to a new pad it lost lock so I said no big deal, I kinda know where the pad I tell it turn to the next building corner to will find me......nothing,,,,,,nothing,,,,,,nothing,,,,,,got radio, says it's searching.......
We walk back to the robot and it's pointed down, I'm looking at it like it's a crazy machine and my colleague is chuckling, he says; "you know what's doing don't you?" throw up my arms,,,,,,"it's looking for the point, but the building corner is on the site elevation of 73' and it's set on control of 7000' feet so it's looking straight down"
DUH of course!!!
I don't know what a T6 is but in the Trimble Access Software you can tell it to only turn the horizontal angle so it doesn't look to the center of the earth. The thing is that has to be done on every setup; it can't be set in the style that I have found.

Doh!! Remembering the old days with the T1 and T2's. And typing on the phone. It is the S6 I was using, really love that machine.
We were staking with a short rod to make it more accurate.
A couple of long days pounding and tacking hubs, but even so the days fly by in the field and it always seems better working with a sledge hammer than with the computer.
As far as the FR clothing, the hard hats, the safety glasses and steel toes,,,,,,,,,those I could do without......
looking at the results screen can save you a trip back to the gun if the search isn't getting it done and you're far enough away from it to not see exactly what it's looking at....... zenith is +/- 180 - bad elevation on a point (maybe it's just hanging it's head about the quality of the operator 😉 )

That makes more sense...
Considering the increasing SIZE of each Wild Instrument (T2 to T3 to T4), a T6 would need to be mounted on a Battle Tank chassis.;)
