So I am shopping for new tribrachs. The ones I inherited have the plummets epoxied in place, so there is no hope of adjustment.
Are the only difference between the regular style and the European style the rounded base? I am particularly concerned about the hole in the side that Leica uses for their measure down tape.?ÿ
Any other differences I should be aware of?
do you have pictures to show? I am unsure what is regular vs european styled tribach and am curious to know.
The top of the line Leica tribrachs will stay in adjustment practically forever. You can tinker with the cheaper ones every day and never get them to stay quite right.
Epoxied in place? Oh....my....
Engineer Supply has a video on Tribrach?ÿ Adjustment.

The hole in the side on the Leica equipment is located on the adapter (also known as a carrier) and not usually on the tribrach itself.
I might be taking a giant leap here, but you sound like you are comparing round base tribrachs and triangular base tribrachs side-by-side (with the adapter included) on the same website. That is usually only possible on a Chinese website. If I am wrong then please ignore me. But if I am right, then please stop what you are doing.
There are a lot of things that you can buy out of China to save a few dollars (non-rotating adapters, cables, etc). Tribrachs are NOT one of those things.
The Chinese ones move. A lot. The build quality in the moving parts and the tensile strength in the materials are just not there.
It might not matter too much for a GPS, but if you are putting a prism (or even worse- a Total Station) on top of a Chinese tribrach then you are asking for trouble.

Looking at the SECO website, particularly the Hungarian made standard precision ones.
These are for GPS and backlight prisms. For robots, I always have them mounted by the dealer, on their preferred tribrach.
