Reasonably priced, AdirPro has created the standard tribrach that is affordable. It has all the standard features including the lithium 3 V battery, the easy on/off switch and is only 2 lbs.

The AdirPro tribrach with laser fits all standard equipment requiring a tribrach (total station, prism, laser level). It's really simple to level using the 3 pronged forced centering. It has a bright, clear laser that allows you to mark a spot with ease. It also has a circular vial with 8-minute sensitivity. And, the 3-volt lithium battery allows for an average of 10 hours of continuous use. And, in order to avoid turning on the laser accidentally, the on/off switch is placed close to the body of the tribrach. This allows the switch to be easy to turn on but avoid accidental battery drainage at the same time.
