Spectra Precision LL300N Self-Leveling Rotary Laser with HL450 Receiver
The Spectra Precision LL300N is the explicit preferred rotary laser for the original truncated Spectra LL30 entry. Its 500 m operating diameter and ±2.2 mm accuracy at 30 m support construction leveling. Four D cells provide approximately 90 hours with alkaline batteries or 45 hours with rechargeable NiMH batteries. The preferred LL300N configuration includes the HL450 receiver and C45 clamp in a small case; tripod and grade rod are separate.
Estimated equipment rental only. Delivery, taxes and applicable fees quoted separately. Final pricing confirmed with dispatch.
