Our Warranty Policy:

1. We provide a one and a half year warranty for GNSS products. For optical instruments (total station, theodolite, level) we offer a 1 year warranty. For accessories, we offer a 6-month warranty.
2. Products under warranty please send us photos to show the problem. We will then decide to send you the parts or you send the instrument back to us for repair. We are responsible for round-trip shipping and other charges. Be sure to contact us first instead of sending us the damaged part directly.
3. For problems beyond the warranty period or warranty liability, we will judge the problem and quote you. You will need to pay for round-trip shipping and maintenance.
4. We provide lifetime technical support for all instruments.

Remarks: Improper use of the instrument and man-made damage to the instrument are not covered by the warranty. Warranty is only for product quality issues.
Our technical support:
Before any shipment, we have a quality inspector doing a careful quality check of the instrument (software installation and testing for GNSS products).
For all GNSS and optical instruments, you will get user manuals and how-to videos.
For novice users, we offer free online training (especially for GNSS products) on receiver configuration, survey software on the controller, and post-processing software operation. We also provide on-site training for a fee if required by the client.
For all products, we offer lifetime and 24-hour technical support.
special service:
If you have a survey project and you are looking for the most cost-effective and efficient way to handle it. Just tell us your project specifications, we will feedback professional advice as a reference.
We provide GNSS raw data processing and CAD drawings to survey field end users.
If you have some damaged instruments and want to pick them up for normal use, please send them in for use. We provide professional maintenance services for various measuring equipment.
