Bosch GCL100-80C-RT 12V Max Reconditioned Connected Cross-Line Laser with Plumb Points

The Bosch GCL100-80C-RT 12V Max Connected Cross-Line Laser is a self-leveling precision layout instrument engineered for horizontal leveling, vertical alignment, and floor-to-ceiling plumb point transfer across commercial interior construction. Powered by a 12V Max 2.0 Ah Lithium-Ion battery platform, this red-beam cross-line laser delivers a 100-foot visible working range with ±1/8-inch accuracy at 30 feet, expandable to 165 feet in pulse receiver mode using an optional LR6 or LR8 receiver. Outfitted with VisiMax thermal energy management, Bluetooth smartphone remote control capabilities, a 4-degree Smart Pendulum self-leveling system, an RM 2 360-degree magnetic rotating mount, 1/4-20 tripod threading, and IP54 dust and splash protection, this 1-2/5 pound layout kit executes one-person alignment tasks.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.

Best Used For:

  • Acoustical Ceiling Grid & Lighting Alignment: Projecting crisp horizontal level lines across 100-foot distances to install suspended ceiling channels and lighting fixtures.
  • Floor-to-Ceiling Plumb Point Transfer: Transferring electrical box centerpoints and mechanical pipe locations vertically between floor slabs and overhead decking.
  • Commercial Cabinetry & Partition Framing: Aligning interior stud walls, glass office partitions, and custom millwork using hands-free smartphone Bluetooth control.

Key Performance & Safety Features

  • VisiMax Energy Management Technology: Automatically monitors diode temperature and power consumption to maintain maximum line brightness and prolong battery life.
  • Bluetooth Connectivity & Leveling Remote App: Allows wireless operation of laser modes and beam brightness adjustment via smartphone to prevent disturbing layout alignment.
  • Smart Pendulum Self-Leveling System: Automatically self-levels within 4 degrees, alerts operators to out-of-level conditions, and locks the pendulum securely for transport.
  • RM 2 360-Degree Magnetic Rotating Mount: Heavy-duty magnetic bracket rotates 360 degrees around plumb points with a fine-adjustment knob for exact positioning.
  • Pulse Receiver Mode Compatibility: Extends layout range up to 165 feet when paired with an optional Bosch LR6 or LR8 laser line receiver.
  • IP54 Dust & Water Splash Protection: Over-molded composite housing seals internal optics against jobsite dust, debris, and water spray.
