Topcon’s RL-200 Series sets new standards for simplicity and accuracy. Rugged, lightweight, and compact, it’s twice the laser at an amazingly affordable price! Topcon’s RL-200 Series revolutionary encoding system provides the highest grade repeatability, 7 arc seconds, of any other laser! No one even comes close. Setup after setup, time after time, you’re always right on grade! Choose from two models, RL-200 1S single slope, or RL-200 2S dual slope. The RL-200 1S provides single slopes from -5% up to +25%. The RL-200 2S provides dual slopes up to +/-10% in the X axis, or up to an industry leading -5 to +25% in the Y axis
