Here is how to use the Leica TS16 for athletics

Well this was obviously not written by Leica or a surveyor, I've never heard a TS16 referred to as an EDM.
I'm going to have to incorporate the use of a 6" carpenter's level in my field operations. It must be way more accurate than the vile level or dual-axis compensator on my MS60.
> way more accurate than the vile level
Come on John, the level isn't that awful!
Or do you mean 'vial' ?
"These operating instructions were produced by Lyle Dahms, Athletics ACT, who arranged the grant
and purchase of the EDM."
Enough said.
Why go through all of that leveling thing with a 6 footer? Just stretch a string line and hang a one inch level vial in the middle of the sag.
It was the first article I found, but the point is that I had no idea that Leica had an "athletics" module for their software, like they do for roads, cogo, etc...
And, the measurements are a resection from the center of the circle to the mark in the field, and the distance is reduced by the radius of the circle.

He didn't make that up, it was taken from a Leica manual...

My only thought is that the instructions are an attempt to be fool proof for a complete novice.

Fascinating Surveyors. I missed seeing any type of measuring tool on the Shot put event (the only one that aired here between my field trips). I would think the biggest error is measuring to the center of the divot made by the shot. You wouldn't want me on the rod thats for sure. Great stuff. I love this forum.
As soon as I saw the photo of the instrument and legs I realized this was an application of the law of cosines Side-Angle-Side solution. At the start of competition the instrument man would zero on the launch edge of the putter’s circle and shoot the distance to the rodman’s prism. When the shot landed the rodman would center the rod in the landing spot and the I-man would shoot angle and distance. The instrument would have the computation pre-programmed and display the SAS solution for him to report to the judges.
Close, they measure from the center of the circle, and subtract the radius of the circle.
