The Spectra Precision GL622N-BCC is a professional-grade dual-slope rotating laser transmitter designed for contractors who demand precision across complex grading, drainage, and site preparation work. This bare unit configuration ships with the transmitter, rechargeable battery pack, charger, and protective carrying case — without a machine control receiver or remote control. It is the ideal choice for crews who already own compatible receivers, manage multiple laser systems across a fleet, or need a direct transmitter replacement without duplicating accessories they already have on the job.
Product Overview
The GL622N-BCC delivers the same dual-grade capability as the full GL622N kit in a cost-efficient package. Dual-axis grade control allows operators to set independent slopes on both the X and Y axes simultaneously, making it well suited for parking lot drainage, road crown work, agricultural land forming, and complex slab pours. The self-leveling system compensates for minor setup variations and the high-visibility laser beam maintains accuracy across long working ranges — up to 2,000 feet in diameter with a compatible receiver. Whether you're working on a municipal drainage project or a large commercial concrete pour, the GL622N-BCC delivers the performance professionals rely on.

Job Applications
The GL622N-BCC is built for demanding site conditions across a range of contractor applications:
- Parking Lot and Road Drainage: Set independent X and Y slopes to achieve precise two-plane drainage gradients without manual string lines or repeated grade checks.
- Agricultural Land Forming: Cover large field areas with consistent grade accuracy, reducing irrigation runoff issues and improving crop field efficiency.
- Commercial Slab and Foundation Work: Maintain tight grade tolerances across large concrete pours, ensuring floors meet spec and drain correctly from day one.
- Pipeline and Utility Trenching: Establish consistent fall-per-foot grades for gravity-fed drainage and sewer lines across long trench runs.

Frequently Asked Questions
- Does the GL622N-BCC include a laser receiver?
- No. The BCC configuration is a bare unit that includes only the transmitter, rechargeable battery pack, charger, and carrying case. A machine control or hand-held receiver must be purchased separately. This makes it an economical option for contractors who already own compatible Spectra Precision receivers.
- Which receivers are compatible with the GL622N-BCC?
- The GL622N-BCC is compatible with a range of Spectra Precision receivers including the HL760 machine control receiver and the HR320 hand-held receiver, among others. If you're unsure which receiver works with your existing equipment, contact the Express Tools team for guidance before purchasing.
- Can the GL622N-BCC be operated remotely?
- The RC402N remote control (sold separately) is compatible with the GL622N and allows full remote operation of grade settings and rotation speed from up to 330 feet away. Remote control is not included in the BCC bare unit package.
- What is the battery life and charging time for the included battery pack?
- The included NiMH rechargeable battery pack provides up to 100 hours of runtime under normal operating conditions. A full recharge typically takes approximately 8 hours using the included charger. The long battery life makes the GL622N-BCC well suited for multi-day continuous operation on large job sites.
