Staking out about 600 feet of line in the deeep Indiana woods today. Was setup on the corner and staking out to a point number that was say 1200 feet away (and maybe 700 feet vertical difference because I was setup on a point with 0.00 elevation). My work today was just to set points on line horizontally toward the 1200 feet away point.
About 200 feet from the gun it would of course say to backup about 1000 feet and go left/right say 0.7 feet. So i would move left/right about 0.7 feet and shoot again, BUT then it would say go 3 FEET left/right.???!!!???
So I cheated and calculated a point at about 600 feet on line and at the same 0.00 elevation as my instrument setup. Then it seemed to behave better when staking toward that 600 feet point.
Then I decided to do the stake to line routine and it behaved even better yet.
Did I have some setting somewhere switch to stake 3D polyline or what?
Maybe it meant for you to go 1000' away then go right .7' as opposed to saying that your current position is .7' offline.

Aha, duh. That explains why it worked better when I did the stake to line.
My arms are like rubber and so is my tired old brain too. That was like work cutting 1000 feet of line.
Thanks man
That's just a guess, but that's the only thing I could think of that would cause the issue you were seeing.

Actually I don't think that does explain it yet. If I moved about 0.7 L/R then the next shot should have been 0.1 or 0.2 L/R not several feet.
Actually the math works. I drew it in CAD just to check my thinking. The DC was telling you to go away 1000' then shift right .7'. If you shift .7' right then go 1000' you'll be 3.5' left of the targeted point. Based on that, at 200' from the instrument, when it said go right 0.7' you were really only 0.12 off line.

Thanks brother. Don't survey sleepy.
It would be alot better to know how far left or right it was to line... than how far right or left, IF you were out at the correct dist.
Hmmm cause then you would clear the correct line.
I am just thinking... or maybe not!

It would certainly be better if it gave the true offset from the line at your current position, but based on his numbers, that's not how it's programed. Just one of those situations where what we think the equip is/should be doing doesn't match what is really happening.
In my mind, this is an example of a situation of out of touch programmers.
IF a human is at the inst, and he looks through the inst at the rodman, and says go left 1 ft, he means one foot. NOT 1 ft out at 3000' away!
This is an example of how our software has yet to be beat into submission!

Stephen's explanation is exactly right.
I have been using TDS SurveyPro for 7 years. That is the way it is set up. If you want to know how far off line you are, you must use the stake a line function.
I was thinking "deep Indiana woods" could have something to do with it.
