Why teams choose STONG

Honest specs. Real calibration. Engineers who answer the phone.

Buying a survey instrument is a multi-year commitment. We treat it that way.

01

Certified calibration

Our laboratory in Bucaramanga performs angular, distance and compensator calibration to manufacturer standards, with a signed certificate for each delivered instrument.

02

Bilingual field training

Every purchase includes on-site or remote training in English or Spanish — from first set-up to advanced workflows like resection, free-station and machine control.

03

Genuine spare parts

We stock OEM batteries, tribrachs, prisms, antennas, controllers and firmware updates so a broken accessory never stops a project.

04

Nationwide service

Authorized technicians cover all 32 departments of Colombia. Average response time on critical service calls is under 48 hours.

STONG calibration workshop
Calibration laboratory

A controlled room. A baseline that has not moved in 12 years.

Every instrument that leaves our facility is checked against a granite reference bench, a 60-metre interior baseline and a precision angular collimator. We do not ship anything that is not provably within manufacturer tolerance.

Calibration is documented with serial number, technician signature, environmental conditions and a digital certificate that you can share with your client or auditor.
