I was just wondering,when traversing,do you let the robotic instrument automatically sight,and turn your angles,or do you still sight the instrument with your eye?
I run my robotic instrument throught it's adjustments,so it works well.
I am letting the gun do the work,but my days doing triangulation sighting with
T2's,I am having a hard time doing it.
I would like do know what other people are doing?
Thanks,
John
our robot is set to the 0mm offset, so the glass needs to be dead on for the angle to be correct. if you use a 360 prism, it should work out.
just let the gun adjust and look, is the target splitting the crosshair?
It was hard to admit, but my robot can achieve better closure than I. Let it track and zero BS along with turning to FS for best results.
Our Robby does it faster and better then we do!

Depending on the instrument, that won't tell you much. Leica instruments don't waste time centering on the prism; they know the offsets from the prism center to the crosshairs and adjust the output angles accordingly. The Trimble 5600 series uses a separate tracker mounted below the scope. Unless the tracker is in perfect alignment with the crosshairs -- an unusual condition -- the crosshairs will be off slightly even when the tracker is centered on the active prism diode. (I don't know if the S6/S8 use the same approach.)
It defeats the purpose of a robot to sight it when that is it's job.
I let ours do all the pointing and turning.
I do both, will turn two sets sometimes with the 'bot, then turn everything off and crank two sets old school. We are 3 or 4 seconds of one another, have more difference (usually 11 seconds) between upright and inverted scope. My previous Leica was always about 8 seconds, but the difference between my eye and ATR was more along the lines of about 10 seconds in a 200m shot, always figured it was because I don't always center behind the gun and was getting a skewed if consistent view through the eyepiece.
Leica is very cool like that, Jim. My old Topcon allows for adjustment so that the instrument centers coincident with the crosshair. The only time it really matters is if you perform an auto center backsight and then a manual foresight. As long as everything is auto, the offsets cancel out.
4 pointings by eye, with most careful focus and parallax adjustments, slowly on a good day = 1.8"
4 pointings by the swiss miss, faster than you can take off your sunglasses = 1.4"
might as well look thru the GPS ... except for all those usual field conditions where you are trying an iffy shot, like foliage on line, or shooting to something far away thru a tight "window" in the foreground, and you want to run the focus barrel through the whole far-to-near field of view, to find that twig that's bending your light waves.

Get one of these and you won't have to worry about twigs on line. I got one last week; I wish I had one 5 years ago.
As far as I know all the robots are still adjusted and collimated by the user telling the robot what direct and indirect sighting IS while you are collimating and adjusting the instrument. So the instrument can be no better than the instrument man that collimated it. That is the way I always thought about it. My two cents, Jp
It sounds like it would be advantageous to take some time and crank some angles by eye, and let the robo do the exact same angles with the exact same setup. That would be the only way I would develop some confidence in the output of the machine.
The only time I look into the scope is shooting something with reflectorless.
My Leica 1105 turns a nice angle, believe me I tested it until I finally had its trust.
