The Leica Rugby 680 is a dual-grade self-leveling rotary laser capable of setting grade in both X and Y axes simultaneously. It delivers ±10 arc-second accuracy over an 800-meter working diameter.
Leica Rugby 680 — Complete Specs, Manual & Guide
Category: Rotary Laser | Brand: Leica | Model: Rugby 680
The Leica Rugby 680 is a top-of-range dual-grade rotary laser for earthmoving, finish grading, and drainage slope work. It sets independent grade in both X and Y directions simultaneously and communicates grade information to compatible rod-eye receivers with a digital display, eliminating the need for manual grade calculations on the grade rod.

Frequently Asked Questions — Leica Rugby 680
What is the Leica Rugby 680 accuracy?
The Rugby 680 delivers ±10 arc-second accuracy, equivalent to ±1/16 inch per 100 feet or ±5mm per 100 meters. This accuracy is consistent across both X and Y grade axes.
How much grade can the Leica Rugby 680 set?
The Rugby 680 sets grade up to 25% (14.04 degrees) on the X axis and up to 10% (5.71 degrees) on the Y axis. This covers the full range of drainage, road crown, and agricultural slope requirements.
What receiver works with the Leica Rugby 680?
The factory-matched receivers are the Leica Rod Eye 160 Digital and Rod Eye 120 Digital. These receivers show the digital grade reading directly on the rod-eye display, which eliminates calculations on the grade rod. Third-party 635nm receivers work for on/off detection but do not display digital grade.
What is the difference between the Leica Rugby 640 and Rugby 680?
The Rugby 680 adds Y-axis (second-axis) grade capability to the Rugby 640's single X-axis grade. The 680 is necessary when setting a two-way slope such as a parking lot crown or highway superelevation. For single-slope drainage work, the Rugby 640 is sufficient.
Can the Leica Rugby 680 be used indoors?
Yes — the Rugby 680 works equally well for interior applications such as suspended ceiling installation and floor leveling. Use the horizontal (auto-level) mode for interior work.
