Excellent for Underground Applications

Outstanding performance in underground mining environments where vertical sight lines are critical. The only minor drawback is the additional weight when working in confined spaces, but the optical performance and durability more than compensate for this consideration.

Frequently Asked Questions

General

✓ Which Leica Total Station models are compatible with the GFZ3 Diagonal Eyepiece? ▾

The GFZ3 Diagonal Eyepiece is compatible with Leica TS03, TS07, TS10, and all TPS series total stations. Please note that it is not compatible with the TS02+ model. Verify your instrument model before purchasing to ensure proper fit and functionality.

✓ What are the primary applications for this diagonal eyepiece? ▾

The GFZ3 Diagonal Eyepiece is specifically designed for steep sight measurements where standard direct viewing becomes uncomfortable or impractical. It excels in applications such as high-rise building surveys, bridge construction monitoring, cliff face measurements, and any scenario requiring extreme vertical angle observations while maintaining operator comfort and measurement accuracy.

✓ Does the diagonal eyepiece affect measurement accuracy or instrument calibration? ▾

No, the GFZ3 Diagonal Eyepiece does not affect measurement accuracy or require instrument recalibration. It functions as an optical viewing aid that redirects the line of sight without introducing measurement errors. All angular and distance measurements maintain the same precision specifications as your total station when using the standard direct eyepiece.

✓ How do I properly install and remove the GFZ3 Diagonal Eyepiece? ▾

Installation is straightforward: ensure your total station is powered off, carefully remove the standard eyepiece by unscrewing it counterclockwise, then thread the GFZ3 Diagonal Eyepiece clockwise until hand-tight. Avoid over-tightening to prevent thread damage. For removal, reverse the process. Always handle with clean hands and store in the provided protective case when not in use.

✓ What maintenance is required for the diagonal eyepiece? ▾

Regular maintenance includes cleaning optical surfaces with lens cleaning tissue and appropriate cleaning solution, checking thread connections for wear, and storing in a dry environment. Inspect the eyepiece rubber cup for cracks or deterioration that could affect viewing comfort. Professional cleaning and calibration should be performed annually or as recommended in harsh operating conditions to maintain optimal optical performance.
