Two total stations, two working styles, not a high-end and a budget option.
PRECISE Total Stations are mechanical instruments built on the same measurement core (2″ angle precision, dual-axis compensation, long-range EDM) but delivered through two different software architectures. T3 puts a full Android computing platform inside the instrument. T3 Lite keeps a traditional keypad-and-screen operating style and connects to third-party field software when a project needs more. Neither is a stripped-down version of the other.

Which One Do I Need
On-Site CAD & Open Android Apps
Your team regularly needs to view CAD layers and select stakeout points graphically on-site, works with large project files in the field, or has standardized on specific Android field apps.
T3
A full Android platform built into the instrument (8-core CPU, 4 GB RAM, 64 GB storage) for on-instrument CAD/DXF viewing, graphical stakeout, and open third-party app installation with no vendor lock-in.
Dusty or Humid Conditions
Your priority is dependable, familiar operation, especially in dusty or humid conditions like tunnels and road corridors.
T3 Lite
Traditional keypad-and-screen operation with high-tolerance absolute encoding designed to keep reading angles accurately even when the encoding disc is partially obstructed; connects to compatible third-party software (DiMap Pro, Surveyor) over Bluetooth 5.0.
Range & Battery Life Compared
Comparing range and battery life across the two instruments.
Not a Clean Split
T3 Lite reaches further on a reflective sheet (2,000 m vs. 200 m) and runs longer on a charge (up to 25 h vs. 20 h single-screen), while T3 reaches further on a single prism (5,000 m vs. 4,000 m). T3's real advantage is on-screen CAD graphics and an open app platform, not a blanket edge in measurement range.
Automatic Target Search / Auto-Aim
Looking for automatic target search, automatic prism tracking, or motorized auto-aim.
Not Offered
Neither T3 nor T3 Lite offers this. Both are mechanical, operator-driven instruments with every sight and turn done by hand. Talk to a PRECISE engineer if your workflow needs a robotic total station.
FAQ
Common Questions
No. They're two different instrument architectures built for different working styles, not a high/low price tier of the same platform. T3 runs a full Android measurement and CAD platform on the instrument. T3 Lite keeps measurement on the instrument in a traditional keypad-and-screen format and adds software over Bluetooth only when a project needs it. Choose based on whether your workflow depends on on-instrument graphics and open apps (T3) or a direct, traditional operating style (T3 Lite).
T3 Lite's angle system, a static absolute encoder combined with high-tolerance photoelectric decoding, is specifically documented to keep producing reliable readings even when part of the encoding disc is affected by dust or condensation, which is a common issue in tunnel and road corridor work.
Not necessarily. Both instruments run onboard measurement programs out of the box. T3's onboard platform additionally supports installing third-party Android apps directly on the instrument. T3 Lite connects to compatible third-party apps like DiMap Pro or Surveyor over Bluetooth 5.0 only if your project needs capability beyond the onboard programs.
No. Both are mechanical total stations: every sight is operator-driven. Neither has automatic target search, automatic prism tracking, or motorized auto-aim.
Both share the same rated prism-free range: up to 1,000 m, with accuracy of ±(3 mm + 2 ppm × D). They differ slightly on reflective-sheet and single-prism range: T3 reaches up to 5,000 m on a single prism and 200 m on a reflective sheet, while T3 Lite reaches up to 4,000 m on a single prism and 2,000 m on a reflective sheet. Actual usable range on either instrument depends on target reflectivity, atmospheric conditions, and line-of-sight quality.
