I have at Topcon GTS-303D & GTS-304 I would like to get rid of. Both can come with either a TDS Ranger or Pentax SC-5 data collector/controller. Both have recently been calibrated and come with all the necessary cables/chords/chargers. I also have a set of Sokkia Locus static GPS units. They are in perfect condition. Let me know if you're interested. Thanks.
