Topcon iM-52 Intelligent Measurement Total Station – 2" Accuracy, Dual Display, Laser Plummet
 |
Model Number: 1023563-04 | U.S. Version | NO Bluetooth
Precision-built for working professionals, the Topcon iM-52 (branded under Sokkia) brings rock-solid reliability and cutting-edge performance to layout and survey crews who need sharp results without overspending. This is not some budget starter kit — it is a full-power, ruggedized total station engineered for jobsite abuse and pinpoint accuracy, all in one streamlined package.
With 2-inch angle accuracy, long-range EDM, and an onboard software suite that makes field data collection smooth and intuitive, the iM-52 delivers real-world efficiency with zero fluff. Reflectorless shots up to 500 meters and prism shots up to 4,000 meters give you serious reach, while USB and RS-232C ports keep your data flowing smoothly between the instrument and your field controller or office software using reliable cable-based connections.
Built to last in the dirt, heat, and rain, the iM-52 is IP66 rated, backed by Topcon’s global service network, and designed to get the job done right — whether you are staking corners, laying pipe, or building infrastructure from the ground up.
Sokkia IM-52 1023563-04 Key Features:
- 30x Magnification & Red Coaxial Laser
Spot distant targets with ease, even in bright sunlight or tricky terrain. The red laser EDM beam delivers fast, precise results at the push of a button. - ±6° Dual-Axis Tilt Compensation
Automatically adjusts for minor leveling errors to maintain angular accuracy — especially helpful on uneven or sloped job sites. - SDRbasic Onboard Software
Out-of-the-box functionality for layout, topo, and basic coordinate geometry is built right in, so you can get to work without extra software or steep learning curves. - Dual-Face Graphic LCD with Backlit Alphanumeric Keyboard
Clear, easy-to-read display from either side of the instrument, with backlighting for early starts and late finishes. - Massive Data Storage for Fast, Reliable Data Collection
Save up to 50,000 points internally with additional support for USB flash drives — perfect for long days or multi-phase projects. - 14-Hour Battery Life
The rechargeable lithium-ion battery powers full-day shifts without a problem, cutting down on field interruptions. - 2-inch Angle Accuracy – Trusted precision for high-stakes layout and control work.
- EDM Power – Reflectorless range up to 500 m, prism range up to 4,000 m.
- Wired Data Workflow (NO Bluetooth) – USB and RS-232C ports provide secure, reliable, cable-based data transfer between the instrument and your compatible field controller or office PC. No Bluetooth radio is included in this 1023563-04 configuration.
- Built-in Laser Plummet – Speeds setup and ensures accurate alignment.
- Dual Display – Allows a single operator to read measurements from either face of the instrument.
- Extremely helpful when the operator is sighting in different directions (especially 180° backsights) and does not want to move around the instrument to read values.
- Built Tough – Weather-sealed IP66 housing resists dust, rain, and jobsite abuse.
Reflectorless Range (up to 500 meters):
-
This means the iM-52 can measure distances without using a prism — just by pointing the laser directly at a solid surface (like a wall, pole, or structure).
-
Extremely useful for shooting hard-to-reach targets, like: building corners, utility poles, elevation marks, inside foundations or pipe inverts.
-
Limitations: You must aim at a surface with decent reflectivity. It will not shoot 500 m to a tree, brush, or water. Bright sunlight and dark surfaces reduce the effective range.
Prism Range Capability (up to 4,000 meters):
-
When paired with a standard survey prism, the laser can measure much longer distances — up to 4,000 meters (2.5 miles).
-
This is useful on long utility runs, pipeline layout, open land surveys, and construction control points across large sites.
Why? Prisms are highly reflective and bounce the signal cleanly back to the EDM, which boosts accuracy and distance.
