Had one of those days yesterday. Repeater battery died and couldn't get radio for more than 3 seconds at a time. Opted to break out the S6 to resect onto some control I already had in the area but just not in optimal locations to occupy. Put up a back sight and got locked onto it and noticed a car parked between me and the back sight but not blocking it and I thought I had plenty of space to shoot over the top of it. While visually I could confirm the S6 was locked onto the prism at all times, the returns appeared to be from a side mirror on the vehicle, even though the cross hairs were nowhere near it, little close maybe, but not close enough I thought it would make any difference. Can anyone give me an idea how wide is the cone of the EDM at roughly 1000' in order to get a bad return??ÿ
Good question. How much error are you seeing just for curiosity sake?
The heat shimmer could also provide a little also, which is why I'm curious.

Stupid random car.?ÿ ?ÿ?ÿ
Looks like about 0.4' horizontally and 0.8' vertically at 1000' if I'm reading that spec sheet correctly.?ÿ?ÿ

About 105' or roughly the distance between the back sight and the car. Ended up just doing a couple short static sessions on my gun points and post processing them this morning so I can go back today and stake the job. I'm just scratching my head how it happened in the first place. Given the parameters jflamm was kind enough to share, it shouldn't have happened and yet, something happened. I'm just not sure what.
Which prism was your S6 locking onto that day? Ordinary prism? Multi-track? ATS-360?
It was a passive prism over a back sight. Never had a problem with the multi-track doing anything like this. I have had plenty of reflective street signs and even snow flakes throw the gun off, but never a car mirror. What threw me was it wasn't locked onto it when I looked through the gun.?ÿ?ÿ
