Tribrach Introduction:

A tribrach can come in handy when you need to use an optical or laser plummet. Plumb bobs can take up valuable time, and they can hard to use in the wind. Using a tribrach with a laser plummet can keep it level, but you can also use it with other survey instruments for the same purpose. Feel free to look at what we have in stock, so you can find a laser tribrach that’s right for you!

How do you make a tribrach on a tripod?

Mark a point on the floor, precisely level the tribrach, and center the image in the optical plummet. Draw a pencil line on the tripod head precisely outlining the tribrach. Rotate the tribrach 120 degrees and fit it to the pencil outline.

Can a tribrach be used with a total station?

You can use a laser tribrach with any type of laser measuring tool, but you can also use it with a total station or any other surveying instrument. This device will allow you to attach your instrument to a tripod, so it can be more stable while you’re using it.

Why does a tribrach need to be adjusted?

The precise alignment of the support area to the base plate of the instrument assures extremely accurate forced centring. The optical plummet is so robust that the need for adjustment during the entire lifetime of the tribrach is practically unnecessary.

How big are the foot Screw on a tribrach?

The hysteresis of Leosurvey tribrachs amounts to a maximum of 3" (1.0 mgon). The foot screws are maintenance-free and have a larger diameter.
