Trimble R12i, R750, TSC5, AND TDL450Hx Base & Rover UHF Surveying RTK kit.
Trimble R12i + R750 Base & Rover RTK Kit — TSC5 + TDL-450H, Restored & Tested
Complete UHF base & rover RTK surveying kit featuring the Trimble R12i rover with IMU tilt compensation, R750 base receiver, TSC5 rugged tablet controller, and TDL-450H external UHF radio. Both receivers fully restored and tested in-house. Turnkey RTK system — pull it out of the case and start collecting points. Ships from Houston, TX.
A complete clean R12i + R750 base/rover kit with TSC5 and TDL-450H from a Trimble dealer typically runs $32,000–$40,000+. Both receivers in this kit are RMA-flagged / in-house repaired, which means they cannot carry Trimble factory warranty — but the hardware is fully restored, tested, and ready to deliver the same RTK performance in the field.
If you don't need Trimble factory warranty support, this kit delivers the same field results for a fraction of dealer pricing. Same Maxwell 6 chipset, same 672 channels, same ProPoint engine, same RTK accuracy. Backed by our 3-month in-house warranty on the complete system.
Both the Trimble R12i Rover and the Trimble R750 Base in this kit are RMA / In-House Repaired units. Please read carefully before purchase:
• Both receivers were previously flagged in Trimble's RMA system as replaced items
• Not eligible for Trimble manufacturer warranty — cannot be registered with Trimble for factory warranty
• Not eligible for Trimble factory service or support
• Not eligible for Trimble firmware option upgrades (additional bands, RTX subscriptions, feature unlocks must be sourced separately)
• Both receivers have been fully restored, tested, and verified in working order by our in-house technical team
• All hardware functions normally — track all GNSS constellations, achieve RTK fix, and operate as standard Trimble receivers in the field
• Backed by our 3-Month In-House Limited Warranty on the complete kit (receivers, controller, radio)
• The TSC5 controller and TDL-450H radio are NOT RMA-flagged — they are standard pre-owned items
If a Trimble factory warranty or factory service eligibility is essential to your purchase decision, this kit is not the right fit. By purchasing, buyer acknowledges the receivers' RMA-flagged status. Contact us with any questions before placing your order.
