Frequently Asked Questions

General

✓ Is the GDF122M compatible with non-Leica total stations? ▾

Yes, the GDF122M features a standard 5/8x11 thread connection that ensures compatibility with most surveying instruments beyond Leica TPS systems, including total stations from major manufacturers like Topcon, Trimble, and Sokkia.

✓ What is the accuracy specification of the 8' circular vial? ▾

The 8' circular vial provides precise leveling with an accuracy of 8 arc minutes per 2mm division, ensuring reliable horizontal positioning for your surveying setup. This sensitivity level is ideal for professional surveying applications requiring accurate instrument leveling.

✓ How does the optical plummet system work for vertical alignment? ▾

The optical plummet uses a precision optical system with crosshairs to provide direct vertical sighting to survey points below. Simply look through the eyepiece, focus on the ground point, and adjust the tribrach position until the crosshairs align perfectly with your survey mark for accurate centering.

✓ What type of tripod connection does this tribrach require? ▾

The GDF122M is designed for standard surveying tripods with 5/8x11 thread connections. This universal threading ensures compatibility with professional survey tripods from all major manufacturers, providing a secure and stable mounting platform for your surveying operations.

✓ Can this tribrach be used for both centering and leveling simultaneously? ▾

Absolutely. The GDF122M is specifically designed for simultaneous centering and leveling operations. Use the optical plummet for precise point centering while monitoring the 8' circular vial for level adjustment. The three adjustable leveling screws allow fine-tuning of both functions independently for optimal setup efficiency.
