The Leica 725858 Small Pipe Laser Target Assembly is a precision-engineered alignment accessory designed to deliver repeatable, accurate bore sighting on underground utility installations. Purpose-built for use with the Leica Piper 100 and Piper 200 pipe laser systems, this target assembly includes optically enhanced inserts calibrated to seat correctly in 6-, 8-, 9-, 10-, and 12-inch diameter pipes. Whether you're laying sewer mains, storm drain lines, or conduit runs, the 725858 eliminates ambiguity during laser setup and keeps your grade and alignment dialed in from the first joint to the last.
Overview & Jobsite Applications
On active construction sites, time lost repositioning or second-guessing your laser setup costs money. The Leica 725858 target assembly is built to reduce that friction. Each insert features clearly defined crosshair centering marks that lock the target to the pipe centerline with no improvising. The high-contrast optical face maximizes beam visibility in low-light trench conditions, giving operators a clear, unambiguous aiming point even at extended sight distances. Compatible with Leica's Piper series, this target integrates seamlessly into workflows where accuracy and speed both matter.

Key Features
- Multi-diameter compatibility: Single assembly covers 6", 8", 9", 10", and 12" pipe sizes — fewer accessories to manage on site
- Crosshair centering marks: Printed or etched reference lines on each insert ensure the target is positioned consistently at true pipe center
- Optical contrast enhancement: Target face is engineered to maximize red laser beam visibility in shadowed and low-light trench environments
- OEM Leica quality: Manufactured to Leica Geosystems tolerances, ensuring compatibility and calibration integrity with Piper 100/200 systems
- Durable field construction: Built to withstand routine handling, mud, and the demands of underground utility work
- Quick setup: Insert design allows fast placement and removal without tools, keeping crew productive between setups
Job Applications
- Municipal sewer installation: Maintain precise grade and alignment across multiple pipe joints on gravity sewer mains where even minor deviation causes costly rework or failed inspections
- Storm drain construction: Set up consistent sight lines through 10" or 12" corrugated or concrete storm pipe runs on subdivision and highway drainage projects
- Underground conduit boring: Use the 725858 target to verify centerline alignment when installing electrical or communications conduit in bored or open-cut trenches
- Utility contractor QC checks: Provide field crews with a reliable reference point for quick alignment verification before backfilling — catching problems before they become change orders

Frequently Asked Questions
- What pipe sizes does the Leica 725858 target assembly fit?
- The 725858 is designed for 6-inch, 8-inch, 9-inch, 10-inch, and 12-inch diameter pipes. If you need coverage for larger diameter pipes, Leica also offers a large pipe laser target assembly for bigger bore applications.
- Is the 725858 compatible with the Leica Piper 100 and Piper 200?
- Yes. The Leica 725858 is an OEM accessory engineered specifically for use with the Leica Piper 100 and Piper 200 pipe laser systems. It is not guaranteed to be compatible with third-party pipe lasers.
- Does this target come with inserts for all listed pipe sizes?
- The 725858 is a small pipe laser target assembly that includes inserts calibrated for the 6" through 12" pipe range. Refer to Leica's documentation or contact Express Tools if you need clarification on which inserts are included for your specific pipe size.
- How do the crosshair marks on the inserts help with alignment?
- The crosshair centering marks provide a fixed visual reference point at the true center of the pipe. When the pipe laser beam strikes the target, the operator can immediately confirm whether the beam is hitting dead center or if the laser needs adjustment — eliminating guesswork and speeding up the setup process.
