Topcon – RL-H4C

Topcon RL-H4C Construction Laser

Topcon’s NEW RL-H4C auto-leveling laser combines precision, versatility and value in one job site tough package. Its super-fast self-leveling motors are accurate to +/-10 arc seconds meaning whether you’re checking grade or setting batter boards you’re going to be accurate the first time. Its high-power 2.4mW diode means you have a 2,600ft. (800m) diameter working radius making it a great reference for machine mounted receivers. The 635nm visible beam means it can even be used for interior alignment applications from setting piers and decking, to wall and even cabinet alignment. All of these features plus optional dry, rechargeable battery operation makes the RL-H4C more than twice the laser offered by anyone else. Download RL-H4C Brochure Here.
