Does the HV302GC-17 come fully assembled, or do I need to configure the laser and receiver before first use?

The HV302GC-17 laser unit and HL760 receiver ship ready for operation—you assemble the tripod following standard setup, mount the laser unit to the tripod head, power on, activate the receiver, and verify beam visibility. No alignment or receiver pairing is required; the system is matched at the factory and tested before shipment.

What's the working range on the HL760 receiver, and will it keep signal on larger jobsites?

The HL760 is engineered for extended-range detection beyond standard receivers, making it suitable for large concrete pours and grading areas where crew members need to work at distance from the laser unit. Actual range depends on ambient light conditions and receiver positioning, but the HL760 is built specifically to handle this package's jobsite demands without frequent signal dropout.

Can I use the HV302GC-17 for both horizontal grade work and vertical plumb tasks without switching equipment?

Yes—the HV302GC-17 delivers simultaneous horizontal and vertical red laser capability in a single unit, meaning you can establish level lines and then activate vertical mode for plumb verification without breaking down and repositioning equipment. This dual-axis design is built for contractors juggling multiple layout tasks on the same project.

How does red laser visibility compare to green laser in outdoor sunlight?

Red laser cuts through outdoor glare and direct sunlight more effectively than green laser alternatives in many contractors' experience, particularly on concrete and light-colored surfaces where the reference line remains visible without washout. Indoor fluorescent environments also see consistent red laser performance without the false readings some green systems experience under certain lighting conditions.

Is the remote control included, and what's its effective range on the jobsite?

Yes, the remote control is included in the GC package and allows you to power and position the laser from distance without returning to the unit after each measurement. Keep the remote within optimal operational range (detailed in the manual for your site conditions) to maintain consistent signal strength; batteries in both the remote and HL760 receiver should be verified before daily startup.

What batteries does the HV302GC-17 system require, and do I need to stock spares for all-day operation?

The remote control and HL760 receiver require separate battery sets for daily operation; specific battery types are detailed in your package documentation. We recommend verifying battery charge before starting each work day and keeping spares on-site to avoid mid-project power loss, particularly on larger pours or grading projects where the laser runs extended hours.

Quick Answer

What is the ProShot Alpha-C Cone Grade Laser Level with R9 Receiver – Model 020-0020CH - 1.7 percent?

The ProShot Alpha-C Cone Grade Laser Level with R9 Receiver (Model 020-0020CH) is a 360° cone beam laser level with a grade range of 0% to ±1.7% in manual mode, offering ±1/16" accuracy at 100 ft and a working range up to 1,000 ft diameter when used with the included R9 Grade Laser Receiver. It features a self-leveling range of ±5°, variable field-selectable rotation speed, and is powered by a rechargeable battery pack with dust and moisture-resistant construction for job site durability.

FIELD APPLICATIONS

What contractors use this grade lasers for

Foundation and Grade Establishment

Contractors use the HV302GC-17 to establish consistent grade lines across foundation footprints and concrete preparations, leveraging the HL760 receiver to maintain laser contact across large pour areas. The horizontal capability creates reference planes for floor slopes, while the remote control lets supervisors position the laser from elevated vantage points without walking back to the unit repeatedly.

Interior Drywall and Finish Installation

Finish crews deploy the vertical laser function to plumb walls and verify stud alignment before drywall application, then switch to horizontal mode for ceiling height and soffit consistency. The red laser visibility indoors cuts through variable fluorescent lighting without the washout common to green alternatives.

Concrete Floor Leveling

Concrete finishers use the horizontal reference to establish and maintain consistent floor elevations across large bays, with the grade rod enabling quick spot verification without manual leveling calculations. The extended-range HL760 keeps crews connected on expansive warehouse or parking structure pours.

Wall and Column Plumb Verification

Masons and framing contractors verify vertical plumb on foundation walls, columns, and structural elements using the vertical laser mode, ensuring structural accuracy before proceeding with upper-story work. The remote control allows operators to maintain sight lines while crew members check multiple reference points with the grade rod.

Multi-Trade Site Coordination

General contractors use the dual-axis capability to coordinate grade, plumb, and alignment across multiple trades—concrete crews establish grade, framers verify plumb, and finish crews reference height lines—all from the same locked-in laser position. This reduces daily setup iterations and keeps the jobsite layout consistent as work progresses vertically.

PRODUCT OVERVIEW

Product Description

Built for Contractors Who Can't Afford to Be Off Grade

The ProShot Alpha-C Cone Grade Laser (Model 020-0020CH) is a professional-grade rotary laser system designed for contractors who demand precise slope control on every job. Paired with the included R9 Receiver, the Alpha-C delivers ±1.7% grade accuracy across large sites — making it the right tool for grading, drainage layout, foundation work, excavation, and site preparation. Whether you're working in bright daylight across a wide-open lot or fine-tuning a drainage swale, the Alpha-C's cone beam technology gives you a consistent, reliable grade reference without the guesswork.

Overview: Where the Alpha-C Performs

The ProShot Alpha-C is engineered for real job site conditions. Its cone-beam rotation pattern projects a continuous 360° laser plane optimized for grade-sensitive applications. The self-leveling mechanism compensates for minor setup variations, so your crew spends less time fussing with tripod adjustments and more time getting work done. The R9 Receiver extends effective range and improves usability in high-ambient-light environments where the naked eye can't catch the beam. From subdivision grading to agricultural drainage to commercial pad preparation, the Alpha-C is a dependable instrument that earns its keep on site.

Job Site Applications

Site Grading & Earthwork: Set consistent cut/fill grades across large pads and subdivisions. The cone beam projects a continuous 360° grade plane so multiple operators and machine operators can work simultaneously from a single instrument setup.

Drainage & Swale Layout: Achieve precise positive drainage slopes for parking lots, residential lots, and agricultural fields. The 1.7% grade range covers the majority of drainage design specifications without needing secondary instruments.

Foundation & Footing Forms: Check and set form elevations with the R9 Receiver for fast, accurate results. Eliminate costly over-excavation and re-work by establishing a reliable elevation reference before concrete is placed.

Road Base & Subgrade Preparation: Use the Alpha-C to control subgrade elevation during road base compaction and prep. Consistent grade control at this stage means smoother paving and better long-term road performance.

Frequently Asked Questions

What is the maximum grade the ProShot Alpha-C can project?: The Alpha-C supports a manual grade range of 0% to ±1.7%. This covers the vast majority of site grading, drainage, and pad preparation applications. For slopes steeper than 1.7%, a pipe laser or slope-specific instrument would be required.
Does the Alpha-C come with a receiver, or is it sold separately?: The 020-0020CH kit includes the ProShot R9 Grade Laser Receiver. The receiver is essential for outdoor use where the laser beam is not visible to the naked eye, and it extends the working range of the instrument significantly.
Is the ProShot Alpha-C self-leveling?: Yes. The Alpha-C features an automatic self-leveling mechanism that compensates for tripod setup variations within ±5°. If the instrument is set up outside that range, it will alert the operator rather than project an inaccurate beam.
What is the effective working range of the Alpha-C with the R9 Receiver?: With the R9 Receiver, the Alpha-C has an effective working diameter of up to 1,000 feet, making it well-suited for large commercial sites, agricultural grading, and subdivision pad work where long sight lines are common.

Why Buy This?

Continuous grade control. No continuous labor.

Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.

Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.

Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
