Your solution to guarantee you’ll get from here to there, quickly, accurately and affordably.

Topcon’s TP-L4 series of alignment lasers offer a combination of features and technology that are proven to meet the demands of contractors more than any other alignment lasers on the market. Whether in the trenches, over-the-top, or laser guidance in mining and tunneling, the TP-L4 is the industry standard.

Super-bright beam

TP-L4’s patented GreenBeam® technology provides the brightest, most visible laser beam. It’s easily seen even in bright sunlight.

Easy-to-see display

The large, backlit LCD is sloped so you can easily see the panel without climbing into the manhole or trench. Safer, faster, better.

Functional accessibility anywhere

The RC-200 remote puts all of the features at your fingertips whether you’re at the laser or up to 660’ away.

Tough and reliable

A utility laser has to meet the demands of tough jobsite conditions, and Topcon’s TP-L4 is by far the toughest. Its all cast-aluminum housing is sealed to keep out moisture, even when submerged. It survives even in the harshest environments.

“Smart Line” (TP-L4GV/AV/G)

Accelerate production by making setup and alignment automatic. Patented scanning technology allows the industry’s only fast, accurate one-person automatic alignment feature: the Smart Line®.

For second day setups, enter the correct grade in the laser and position the target at the end of yesterday’s last section of pipe. Press the Smart Line button (on the laser or remote) and the laser automatically finds the target center, letting your crew start another day’s production without delay. 

When combined with features like SmartLine® auto-alignment, the world’s most accurate grade mechanism, power options that keep you working when other lasers have given up, it’s no wonder Topcon has set the standard.

There are five TP-L4 models to choose from, which means five ways to get there from here within your budget.
