Big power, small package
Easy-to-use, highly accurate, rugged, and reliable the iM-100
manual total station is perfect for entry-level site layout and
surveying. The iM-100 is built to be your hardest worker, made
to withstand even the toughest conditions and providing up to
28 hours of battery life*1.
Like all of our products, you can customize it to meet your
needs and create your own workflows.
• Fast, accurate, and powerful EDM
• Reflectorless up to 800 meters
• Dual-axis compensation
• Waterproof IP66 rating
• Up to 28 hours in battery life*1
High-end performance
Featuring a new top line EDM, the iM-100 is fast, accurate,
and powerful. It has 1.5 mm / 2 ppm accuracy and is able
to measure up to 5,000 meters to standard prisms, and in
reflectorless mode measures up to 800 meters at an
incredible 2.0 mm + 2 ppm accuracy.
Precise positioning
Dual-axis compensation ensures stable measurements
even on rough terrain. The compensator automatically
corrects both horizontal and vertical angles and allows
for more accurate instrument setups and measurements.
Ready for the field
In addition to an IP66 certification, the
iM-100 is guaranteed to protect against
dust and be waterproof up to one meter.
It comes in a regular model which can
operate in temperatures ranging from
-20ºC to 60ºC, and a low-temperature
model that can handle -35ºC to 50ºC*2.
Stay charged
The iM-100 lets you get more done on the
job without the need to recharge during
the workday. Typical battery life is tested
to 28 hours in Eco mode and 21 hours in
regular mode.
Get connected
With Bluetooth® wireless communication
you can deliver data instantly to your
Bluetooth-equipped controller, with no
external antenna needed.
*1 Eco Mode. *2 Region Dependent.

Superior storage
Don’t worry about how or where to
store all your data, the iM-100 has
you covered. With 50,000 pts internal
memory and up to 32GB USB flash drive
support, you can easily store all data in
the field that you need.
