Frequently Asked Questions — Sokkia CX-105
What is the Sokkia CX-105 angular accuracy?
The CX-105 delivers 5-arc-second angular accuracy using an absolute encoder. This matches industry standard accuracy for general construction layout, boundary surveys, and topographic fieldwork.
What is the EDM range on the Sokkia CX-105?
Using a single 360-degree prism, the CX-105 measures distances to 4,000 meters. Reflectorless (prismless) measurements reach 500 meters on a white card surface at ±(5mm + 3ppm) accuracy.
How does the Sokkia CX-105 compare to the CX-50?
The CX-105 offers extended EDM range (4,000m vs 3,000m on the CX-50) and IP66 weather resistance vs IP54 on the CX-50. The CX-105 also has longer battery life at 14 hours vs 10 hours. For demanding outdoor use or longer-range measurements, the CX-105 is the better choice.
What field software works with the Sokkia CX-105?
The CX-105 runs Sokkia SDR software onboard. It communicates with external data collectors (Sokkia SHC336, Juniper Archer) via Bluetooth or RS-232. Third-party software using standard survey protocols is also compatible.
Is the Sokkia CX-105 IP66 rated?
Yes — the CX-105 carries an IP66 rating, meaning it is fully protected against dust and powerful water jets. This makes it suitable for use in rain and dusty construction environments.
