Sokkia DT950G Digital Theodolite Kit with 9 Second Accuracy - Model

The Sokkia DT950G Digital Theodolite Kit (1037809-08) delivers professional-grade angular measurement accuracy for contractors, surveyors, and construction crews who need reliable layout precision without the overhead of a full total station. With 9-second horizontal and vertical accuracy and a clear digital display, the DT950G eliminates the misreads and interpolation errors that plague traditional optical instruments — keeping your layout tight and your crew moving.

Overview & Jobsite Applications

Designed for demanding commercial, industrial, and infrastructure jobsites, the Sokkia DT950G handles the angular control tasks that define structural accuracy: column line layout, beam alignment, pipe and duct plumbing, and control traverse work. Its rugged housing stands up to dust, humidity, and the everyday punishment of active construction sites. The digital readout provides instant angle display in degrees-minutes-seconds or decimal degrees, reducing setup time and operator fatigue on high-volume layout days.

Job Applications

Structural Steel and Column Layout: Set precise column grid lines and verify structural steel plumb during erection. The DT950G's 9-second accuracy keeps multi-story work on tolerance from foundation to roof deck.

Pipeline and Utility Alignment: Maintain horizontal and vertical angle control for gravity-flow sewer, storm drain, and pressurized pipeline installation where elevation and direction tolerances are critical.

Industrial Equipment Setting: Align conveyor systems, turbine bases, press foundations, and large mechanical equipment where angular deviation directly affects performance and longevity.

Control Traverse and Angle Closure: Run angle-only traverses for site control networks, boundary retracement, and construction baseline establishment when distance measurement is handled separately.

Frequently Asked Questions

What is the difference between the DT950G and a total station?

The DT950G measures horizontal and vertical angles only — it does not include an EDM (electronic distance measurement) module. Total stations combine angle measurement with laser distance measurement in one instrument. The DT950G is the right choice when you need precise angle control at a lower cost, or when distance measurement is handled by tape, chain, or a separate EDM unit.

Is the Sokkia DT950G suitable for outdoor use in wet conditions?

Yes. The DT950G carries an IPX6 waterproof rating, meaning it is protected against powerful water jets from any direction. It is designed for active construction environments and can handle rain and jobsite wash-down conditions. However, it should not be submerged.

What batteries does the DT950G use, and how long do they last?

The DT950G runs on standard AA alkaline batteries, making field replacement simple and cost-effective. Under normal operating conditions, battery life is approximately 60 hours of continuous use. Keeping a spare set on site is always recommended for extended layout operations.

Does this kit include a tripod?

The 1037809-08 kit includes the DT950G instrument, a tribrach with optical plummet, and a hard-shell carrying case, but does not include a field tripod. We recommend pairing this kit with a Sokkia aluminum surveying tripod, available separately on our site, to complete your setup.
