Every contractor knows drops happen. The Topcon LS-100D comes wrapped in a heavy-duty rubber armor housing that’s built to take a beating. Whether it’s knocked off a rod, dropped from scaffolding, or banged around in the truck, this receiver is protected from the daily abuse of the jobsite. That means fewer replacements, less downtime, and more time getting the job done.
With 5 selectable accuracy settings — ±0.02″, ±0.05″, ±0.10″, ±0.20″, and ±0.50″ (±0.5 mm to ±10 mm) — you’re in full control of how tight you need to dial it in. From rough grading to ultra-precise elevation checks, the Topcon LS-100D adapts to the job at hand with unmatched flexibility.
