Android controller supplied with SurvPC or SurvCE, popular with mixed-brand fleets. Ovento Systems carries the Carlson RT4 as used and refurbished stock within our survey accessories & data collectors range, sourced through equipment liquidations, service company fleet upgrades and OEM trade-ins across North America and Asia.

Controllers are checked for screen, keypad, battery and radio function, prisms are inspected for chips and constant accuracy, and software licence transferability is confirmed in writing. Stock is held in Plano, TX and normally despatches within one business day of order confirmation. Most enquiries on this model come from survey crews replacing damaged targets and dealers completing incomplete instrument kits. If you need several, or need them matched, say so on the request and we will quote as a set.

What is included with the RT4

The instrument itself, its standard supplied leads or probes where noted, and a written condition report. Cases, modules and calibration certificates are quoted separately so you only pay for what you actually need. If you are completing an existing kit, tell us the part numbers you are missing and we will check accessory stock against them.
