Has any of you other Geomax users run into a problem with your traverses not ever closing?

Also no, though in reference to a GeoMax Zoom80R.  Have you eliminated the obvious problems, like shaky setups, loose tripods or sloppy sights?  That instrument should be accurate enough that traverse closures aren't a problem.

Yes. Two 3 setup traverses all wide open, solid ground, tripod tight, rod plumb and used with bipod. Closing in between .12 to .15 over 1600 feet

Are you using OP tribrachs or the laser plummet?   An OP out of adjustment can add up quickly.

Data collector or manual notes?  Prism offsets verified for each shot?  Do the angles close?  Lots of things to check...
