Purpose-Built Depth Control for Excavation Operations
The Leica MC200 Depthmaster (742701) is a professional-grade machine receiver engineered specifically for vertical excavation applications. Whether you're cutting trenches for utility installation, digging foundations to tight tolerances, or grading with a dozer, the MC200 delivers the precise, reliable depth feedback contractors depend on. Its 200-degree laser coverage pattern is purpose-matched to excavator boom geometry, eliminating the dead zones and signal gaps that plague general-purpose receivers on dig-cycle equipment. When depth accuracy directly affects project compliance and rework costs, the MC200 is the receiver serious machine operators reach for.
Overview & Jobsite Applications
The MC200 Depthmaster integrates seamlessly with Leica rotating laser systems to provide real-time grade and depth information directly to the machine operator. The receiver mounts to the excavator stick or dozer blade and communicates cut/fill deviation through clear audio and visual indicators, keeping the operator on grade without repeated manual checks. NiMH rechargeable batteries support full shift operation, reducing downtime and consumable costs on active jobsites. The rugged housing is built to withstand the vibration, dust, and moisture common in earthmoving environments.

Job Applications
Utility Trench Excavation: Maintain consistent invert elevations across long trench runs for sewer, water, and conduit installations — reducing over-excavation and bedding material waste.
Foundation Digging: Hit bottom-of-footing elevations on the first pass, eliminating hand-digging corrections and keeping concrete pours on schedule.
Dozer Rough Grade: Use the MC200 on crawler dozers to establish consistent subgrade elevations before fine grading equipment moves in.
Pond & Basin Excavation: Control depth uniformity across wide excavation areas for retention basins, detention ponds, and agricultural earthworks.

Frequently Asked Questions
- What makes the 200-degree coverage angle important for excavators?
- Excavator booms and sticks move through a limited arc during the dig cycle — unlike dozers or graders that operate in a full rotational environment. The MC200's 200-degree window is matched to this geometry, ensuring the receiver stays in contact with the laser plane throughout the entire working arc without requiring the operator to reposition the unit.
- Is the Leica MC200 compatible with all Leica rotating laser models?
- The MC200 is designed for use within the Leica machine control ecosystem and is compatible with the Leica Rugby series and other Leica rotating lasers that operate at standard red-beam wavelengths. Always confirm compatibility with your specific laser transmitter model before purchase — our team can assist with pairing questions.
- How long do the NiMH batteries last on a full charge?
- NiMH battery runtime depends on operating conditions, display brightness settings, and ambient temperature. Under typical field use, the MC200 is designed to support a full working shift. Keeping a charged spare pack available is standard practice on high-utilization jobsites.
- Can the MC200 be used on a dozer as well as an excavator?
- Yes. While the MC200 is optimized for excavation geometry, its 200-degree coverage and rugged construction make it suitable for dozer blade applications as well. Use the appropriate Leica mounting hardware for your specific machine type to ensure secure attachment and correct receiver orientation.
