Components: PG-A1 GPS receiver, GRS-1 data collector, 5 batteries (BT-66Q), Seco pole and bipod, pole mount arm, charging cables, USB-mini data transfer cable, protective travel
Details: Purchased used from a local Topcon distributor in fall of 2016 for around $6000 (which was a good market price back then). Could use some new batteries, but otherwise the unit and software function great. We've been using the unit's magnet field software in various states and on various networks for the past 2 years for great results.
