FAQs

Topcon OS-105
Can I hire the Topcon OS-105 from PQS Survey Ltd?
Yes, the OS-105 remains a popular choice in our hire fleet for contractors moving from standard theodolites to total stations. Hiring from PQS Survey Ltd ensures you receive an instrument pre-loaded with MAGNET Field software, a fresh calibration certificate, and full technical support without the capital outlay of a robotic system.

What are the key benefits of the “On-board” design of the OS-105?
The “OS” stands for On-board Station, featuring a full-colour Windows CE touchscreen interface. This allows you to run MAGNET Field software directly on the instrument, providing a graphical view of points and lines and eliminating the need for an external data collector.

How accurate is the OS-105 for engineering and construction?
The OS-105 offers 5-arc-second angular accuracy, making it the “workhorse” for general site layout, earthwork volumes, and housing projects. While 1-second or 2-second models exist for extreme precision tasks like bridge work, the 105 is ideal for most civil engineering applications.
Topcon OS-105
What is “LongLink” and how does it change the workflow?
LongLink is Topcon’s Bluetooth Class 1 technology, providing a wireless link between the total station and a field controller up to 300 metres away. This allows the person at the prism pole to trigger measurements and enter codes, reducing communication errors and improving efficiency for two-man crews.

Is it still worth using a manual station like the OS-105 when robotic stations exist?
Yes, as the OS-105 is significantly more affordable to hire and purchase while being more robust for daily site tasks. it provides a high-tech graphical interface and is simpler to learn for staff familiar with traditional surveying without the complexity or cost of a motorized robotic system.

What is the “TSshield” security system?
TSshield is a telematics-based module that allows you to remotely lock the instrument if it is lost or stolen. It also provides the instrument’s location to the office and notifies you on-screen when firmware updates are available, protecting your investment from both theft and obsolescence.
