Spectra DG613-13 Dialgrade Pipe Laser OTT Over-the-Top Package with Precision Scope, Power Outlet Charger, Two Rechargeable Batteries

Overview

The Spectra DG613-13 Over-the-Top (OTT) Package is a fully integrated solution for crews that demand maximum versatility and minimal downtime. This complete system bundles the proven DG613 dialgrade laser with a precision site scope, allowing operators to sight grades on nearby grade points without leaving the instrument. Designed for professional pipe laying, grading, and underground utility work, the DG613-13 delivers exceptional accuracy and reliability in the harshest job site conditions.

What sets this Over-the-Top package apart is its comprehensive configuration. You're not just getting a laser—you're getting a complete work-ready system with dual rechargeable batteries for extended runtime, a power outlet charger for overnight charging, and the invaluable precision scope that transforms your laser into a dual-purpose instrument. Whether you're setting up trenches, installing storm drains, or laying sewer lines, the DG613-13 OTT Package provides everything you need to establish and verify grade quickly and accurately.

The dialgrade design offers exceptional flexibility with adjustable pitch settings from -10% to +40% grade, making it ideal for a wide range of applications from flat concrete slabs to steep drainage runs. The rugged construction withstands drops, vibration, and the inevitable bumps of daily construction use, while Spectra's legendary reliability ensures your crew stays productive day after day.

Job Applications

• Sanitary and Storm Sewer Installation: The precise grade control ensures proper flow rates and prevents settling or backup issues. The dialgrade adjustment allows operators to match engineered plans exactly, while the visible red beam provides clear alignment in deep trenches where GPS signals may be unreliable.
• Water Main and Force Main Projects: Accurate slope control is critical for preventing air pockets and ensuring proper drainage during maintenance. The DG613's ±1/8 inch accuracy at 100 feet guarantees installations meet municipal specifications, and the dual battery system keeps crews working through full shifts without interruption.
• Agricultural Drainage Tiles: Proper field drainage requires consistent, gentle slopes often less than 1%. The DG613's 0.01% grade increments allow precise control for optimal water removal, while the rugged construction withstands the mud, moisture, and rough handling common in agricultural environments.
• Foundation Footing and Concrete Work: The OTT scope enables operators to verify existing grades and benchmarks before establishing laser references, eliminating costly errors. The flat-grade capability and high visibility beam make it ideal for large slab pours and foundation work where level references are critical.
• Underground Utility Corridors: When installing conduit banks, cable runs, or multi-utility trenches, the remote control allows grade adjustment without entering excavations. This improves both safety and efficiency, especially in confined spaces or unstable soil conditions.
• Culvert and Drainage Structure Installation: The wide grade range (-10% to +40%) accommodates everything from flat-bottom culverts to steep outfall structures. The precision scope helps verify invert elevations against survey stakes, ensuring proper tie-ins to existing drainage systems.

FAQ

What is the advantage of the Over-the-Top scope on this package?

The OTT precision scope allows you to sight-in on nearby grade stakes, benchmarks, or survey points without removing the laser from the pipe or bringing in a separate optical level. This speeds up setup significantly and helps verify you're shooting to the correct grade before your crew starts digging or laying pipe. It essentially gives you two instruments in one, eliminating the need to carry both a laser and an optical level to the job site.

How long does it take to charge the batteries, and can I use the laser while charging?

The included power outlet charger fully recharges a depleted battery in approximately 4-6 hours, making overnight charging convenient. While the DG613 can operate while plugged into the charger, this is typically only used for extended indoor applications. For field work, the dual battery system is designed for hot-swapping—keep one battery charging in your truck or job box while using the other, ensuring virtually unlimited runtime.

What's the difference between the DG613 and less expensive pipe lasers?

The DG613 offers superior grade adjustment precision (0.01% increments vs. coarser adjustments on budget models), longer range capability, better accuracy (±1/8" vs. ±3/16" or wider), and significantly more durable construction with full IP68 waterproofing. The dialgrade interface is also faster and more intuitive than cheaper push-button systems, saving time on every setup. Most importantly, Spectra's build quality means this laser will last 10+ years with proper care, versus 2-3 years for economy units.

Can this laser be used for horizontal boring or directional drilling operations?

While the DG613 excels at open-cut pipe installation, it's not designed for horizontal boring applications. For directional drilling and guided boring, you'll need a specialized bore laser like the Spectra DG511 or DG711 series, which mounts inside the boring machine and transmits a signal to receivers in the bore head. However, the DG613 is excellent for establishing reference grades for boring entry and exit pits, and for verifying the final grade of installed pipe after the bore is complete.
