BUYER QUESTIONS
Before you choose a configuration.
These answers help start the right technical discussion without overstating information that needs project-level confirmation.
Start a T50 enquiryWhen is the T50 green laser useful?
The laser function is intended for points that are difficult to reach directly with a pole. Assess line of sight, surface condition and the documented measurement range before using it for the field task.
Can T50 be supplied for a UHF radio workflow?
The latest brochure lists an integrated 410–470 MHz UHF radio. Share the destination country and local radio requirement so the final configuration can be checked before supply.
What should a T50 enquiry include?
Provide the country, correction source, survey or layout task, requested software and whether laser or AR stakeout is required.
PROJECT ENQUIRY
Need a T50 configuration for a live project?
