My brand new total station gave bad readings on a site in Austin last Tuesday

I was setting control points on a 12-acre residential development just north of downtown. The unit said everything was fine but I kept getting closure errors over 0.05 feet. After 45 minutes of re-shooting the same backsight, I pulled the battery and found a hairline crack in the tribrach adapter plate. Swapped it with my backup unit from the truck and the errors dropped to 0.01 feet. The dealer said it was probably a casting flaw from the factory. Cost me half a day of layout work and I had to push the concrete pour to Wednesday. Has anyone else seen these tribrach plates fail like that on a newer instrument?

...wait, a crack in the tribrach adapter plate? That's wild. I've seen those things take a lot of abuse on job sites, but a hairline crack from the factory on a brand new unit sounds like a real pain. Glad you caught it before the pour, that could've been a total disaster.

Yeah for REAL, that saved a whole lot of headache and money.
