Topcon Total Station GM-100 Series: The Ultimate Guide to Features and Total Station Price in Bangladesh
In the rapidly growing construction and infrastructure sector of Bangladesh, precision is the cornerstone of success. Whether it’s the development of the Dhaka Metro Rail, massive flyovers, or high-rise residential complexes, the need for accurate measurement has never been higher. Among professional surveyors, the Topcon GM-100 Series is widely regarded as the “Gold Standard.”
In this guide, we will explore why this Japanese-engineered device is a market leader and provide a detailed analysis of the Total Station Price in Bangladesh for 2026.
1. Why Choose the Topcon GM-100 Series?
The Topcon GM-100 (Geodetic Measurement Station) series—including the GM-101, GM-102, and GM-105—is designed for surveyors who demand high performance in a compact, sleek body. It succeeds the legendary ES series, offering faster EDM (Electronic Distance Measurement) and significantly enhanced security.
Key Technical Specifications:
-
Measuring Range: 6,000m with a prism and an incredible 1,000m in reflectorless mode.
-
Angle Accuracy: Available in 1”, 2”, 3”, and 5” models.
-
EDM Speed: Fine measurement in just 0.9 seconds.
-
Storage: Internal memory stores 50,000 points; supports up to 32GB USB flash drives.
-
Environmental Rating: IP66 (Highest rating against heavy dust and rain).
2. Total Station Price in Bangladesh (2026 Update)
Understanding the Total Station Price is crucial for budgeting your surveying project. In Bangladesh, the price is influenced by model accuracy, import duties, and bundled accessories (like tripods, poles, and prisms).
Below is the estimated market price list for the Topcon GM-100 Series in Bangladesh:
| Model Model | Accuracy | Estimated Price (BDT) | Best Use Case |
| Topcon GM-101 | 1″ (One Second) | ৳5,85,000 – ৳6,50,000 | High-precision bridges & monitoring |
| Topcon GM-102 | 2″ (Two Second) | ৳5,30,000 – ৳5,80,000 | General construction & topography |
| Topcon GM-105 | 5″ (Five Second) | ৳4,30,000 – ৳4,85,000 | Land partitioning & road works |
Pro Tip: Always look for “Authorized Dealer” certifications in Bangladesh. While unauthorized imports might offer a lower Total Station Price, they often lack the crucial TSshield™ activation and valid service warranties.
3. Revolutionary Technology: What Sets It Apart?
TSshield™ Security System
A common concern for surveyors in Bangladesh is the security of their equipment. The GM-100 features TSshield™, a telematics-based communications module. If your device is stolen, you can send a signal to remotely lock the instrument, rendering it useless to thieves. It also notifies you of any available firmware updates.
Ultra-Powerful EDM
The newly designed EDM unit allows for ultra-precise measurements. The narrow beam width of 13mm (at 30m) ensures you are hitting the exact point you intended, even through fences or tree branches.
Exceptional Battery Life
Surveying in remote areas of Bangladesh can be challenging due to lack of power. The GM-100 series solves this with a battery life of up to 28 hours in Eco mode. This effectively allows for 3 to 4 days of field work on a single charge.
4. Purchasing Advice for the Bangladeshi Market
When searching for the best Total Station Price, keep the following factors in mind:
-
Calibration Certification: Ensure the supplier provides a valid calibration certificate. Precision instruments drift over time, and a pre-calibrated unit is essential for immediate work.
-
After-Sales Support: In Bangladesh, finding a supplier with a dedicated service center is vital. Look for companies like Survey Instrument BD or TS Geosystems that offer long-term technical support.
-
Warranty: Most authorized Topcon units come with a 1-year service warranty. Always clarify if the price includes the “Full Kit” (Tripod, Prism, Pole, and Battery).
5. Conclusion
The Topcon GM-100 Series is more than just a measurement tool; it is a long-term investment in your engineering accuracy. While the Total Station Price in Bangladesh may vary based on model specifications, the ROI (Return on Investment) is undeniable through reduced errors and faster project completion.
Whether you are a freelancer or represent a large construction firm, the GM-101 or GM-105 will serve as a reliable partner in the toughest field conditions.
