- Wide grade range (up to 25% slope) without slope blocks
- Extra-long battery life (65 hrs)
- Increased range - up to 2,500 ft. (770m)
- Graphical display
- Full function remote (RL-100 2S only)
- Current grade
- Masking - electronically shutter up to three quadrants to avoid interference with other lasers on the site.
- Selectable rotation speed: 300, 600, or 900 rpm
- Selectable remote channel: select any of nine channels when using more than one RL-100 2S in proximity to each other.
