$ Why Thousands Less Than Dealer Pricing?

Trimble dealers price clean, warranty-eligible R12 receiver kits at $18,000–$19,500. This unit is RMA-flagged, which means it cannot carry a Trimble factory warranty — but the hardware is identical, fully restored, and field-tested. If you don't need Trimble factory warranty support, you save thousands for the same in-field performance.
