The Topcon LS-110D is Topcon’s advanced digital laser receiver built for grade control on grading, excavation, and foundation work. This listing is for the receiver unit only — ideal if you already own a Sensor Holder 110 or prefer to use your own rod mount. If you need the complete setup out of the box, see the LS-110D Kit (part# 1091205-01) which includes the Sensor Holder 110 bracket.
ⓘ Rod Bracket Not Included: This receiver ships without the Sensor Holder 110 screw-mount rod bracket. The Sensor Holder 110 is available separately — part# 1019505-01. See the LS-110D Kit (1091205-01) if you need bracket + receiver together.
