Overview
The Spectra Precision 956 Adjustable In-Pipe Target delivers professional-grade laser beam detection for municipal and commercial pipeline installations ranging from 6 to 21 inches in diameter. Engineered with optically enhanced reflective surfaces, this target provides maximum visibility in challenging underground conditions where ambient light is minimal and precise grade verification is critical. The adjustable design allows contractors to quickly position the target at the exact invert elevation, eliminating guesswork during laser-guided excavation and pipe laying operations. Built with impact-resistant materials that withstand the rigors of sewer, storm drain, and utility installations, the 956 has become an industry standard for crews who demand reliability in wet, muddy, and confined workspace environments. At just $139.95, this target pays for itself on the first job by reducing grade errors and callbacks.

Job Applications
- Municipal Sewer Line Installation: The adjustable design lets you verify precise invert elevations during gravity sewer installation, preventing costly flow problems and ensuring proper drainage velocity from manhole to manhole.
- Storm Drain Projects: Optically enhanced surfaces remain visible even when water is flowing through the pipe during installation, allowing grade verification without stopping work during wet weather conditions.
- Commercial Site Development: Compact profile fits inside 6-inch building drains and site utilities where larger targets won't work, enabling laser-guided installation in tight residential and light commercial applications.
- Culvert Rehabilitation: The rugged construction withstands the debris and rough handling common in culvert replacement projects where targets get moved frequently between measurement points.
- Utility Conduit Installation: Works perfectly for electric, fiber optic, and communication conduit banks where maintaining consistent grade prevents water pooling and cable damage over the system's lifespan.
- Trenchless Pipe Bursting: Small footprint and durable design make it ideal for checking grade during pipe bursting operations where targets must fit through restricted openings and survive high-vibration environments.

FAQ
- Will the Spectra 956 target work with my non-Spectra brand pipe laser?
- Yes, the 956 is a universal target that works with all major pipe laser manufacturers including Topcon, Leica, Trimble, CST/Berger, and Johnson. The optically enhanced reflective surface is designed to reflect any visible laser beam regardless of brand.
- What's the smallest pipe diameter I can use this target in?
- The Spectra 956 is rated for pipes as small as 6 inches in diameter. For smaller pipes (4-inch), you'll need a compact target like the Spectra 954. The adjustable legs on the 956 collapse to fit 6-inch pipe but provide the stability needed for accurate positioning.
- Can I leave this target in the pipe overnight or during concrete work?
- The 956 is built with sealed, water-resistant construction that handles wet conditions well, but it's not designed to be buried in concrete or backfill. Always remove the target before pouring concrete or backfilling. The durable construction does allow it to stay in place overnight during multi-day installations without concern for dew or rain exposure.
- How do I clean the target face if it gets muddy on the jobsite?
- Simply wipe the reflective surface with a damp cloth or rinse with water. The optical enhancement coating is durable and won't scratch from normal cleaning. Avoid harsh chemical solvents or abrasive scrubbing pads. For stubborn mud, let it dry and brush off gently before wiping clean.
