SitePro Thumb-Release Pole Tripod

The ProShot Alpha-C Cone Grade Laser (model 020-0020C) is a professional-grade, cone-style laser built for contractors who need accurate, repeatable slope on demanding jobsites. Whether you're laying pipe, establishing drainage fall, or finish-grading a site, the Alpha-C delivers a full 360-degree cone beam that lets your entire crew — excavator operator, pipe hands in the trench, and grade checker at the far end — all work off a single instrument simultaneously. The included R9 receiver rounds out a complete, job-ready system from the moment you open the case.

Overview & Jobsite Applications

Cone grade lasers are the preferred tool on open-trench pipe and drainage jobs because the cone beam eliminates the dead zones that plague rotating lasers used at steep angles. The Alpha-C projects a continuous conical plane at your programmed grade, so there's no waiting for a sweep — the beam is always on. With a 4% (approximately 2.3°) slope range, it handles everything from shallow storm drain falls to steeper sanitary sewer grades, all while maintaining the submillimeter repeatability that production pipe crews demand. The R9 digital receiver extends usable range and provides clear in-grade, above, and below indication even in bright outdoor conditions.

Key Features & What's in the Kit

• 360° Cone Beam: Continuous grade plane with no sweep — every crew member reads the same plane at the same time
• 4% Slope Capability: Covers the majority of gravity-flow pipe and drainage grade requirements
• R9 Digital Receiver: Clear in-grade / above / below readout; works in full sunlight at extended distances
• Automatic Self-Leveling: Instrument compensates for minor setup variations; out-of-level alarm shuts beam if tolerance is exceeded
• Rugged, Jobsite-Ready Housing: IP54 rated, shock-resistant chassis built for trench and grade work environments
• Simple Grade Entry: Intuitive controls for fast setup — dial in your fall and get to work
• Complete Kit: Laser, R9 receiver with clamp, carrying case, battery charger, and target card all included

Job Applications

Sanitary & Storm Sewer Installation: Dial in the design fall percentage and give your pipe crew a reliable grade reference from manhole to manhole. The cone beam means the excavator operator and the pipe layer can both read grade without moving the instrument.

Drainage Swales & Culverts: Establish consistent fall across long drainage runs. The R9 receiver clips to a grade rod for fast check shots at any point along the swale without repositioning the laser.

Sub-Base & Finish Grading: Set a reference plane for machine operators cutting sub-base or motor grader operators pulling finish grade on sloped parking lots and access roads.

Irrigation & Agricultural Tile Drainage: Maintain precise, shallow fall on irrigation laterals and subsurface tile systems where consistent low-percentage grade is critical to system performance.

Frequently Asked Questions

What is the maximum slope the ProShot Alpha-C can project?

The Alpha-C has a grade range of 0–4%, which covers the overwhelming majority of gravity-flow pipe, storm drain, and drainage applications. If your design calls for slopes steeper than 4%, a pipe laser with higher grade range would be the appropriate tool.

Does the Alpha-C come with a receiver, or is it sold separately?

The 020-0020C kit includes the R9 digital receiver, mounting clamp, carrying case, and charger — everything you need to start shooting grade on day one. No separate receiver purchase is required.

Can multiple crew members read the cone beam at the same time?

Yes. The continuous 360-degree cone beam is always on and visible from any direction around the instrument. Your excavator operator, pipe crew in the trench, and a grade checker 300 feet away can all read the same plane simultaneously — a key advantage over rotating lasers on busy pipe jobs.

Is the Alpha-C suitable for use inside a pipe?

The Alpha-C is a cone-style grade laser optimized for open-trench and surface-grade work. For shooting grade inside a pipe (e.g., directing a pipe laser target from inside the barrel), a dedicated pipe laser is the correct instrument. The Alpha-C is best used above grade to provide a reference plane for the pipe crew working at the trench.
