For use in conjunction with the GSL 2 Floor Surface Laser Level, the Bosch RC 2 Remote Control can be used to rotate the level from up to 20m away. Three different rotational speeds give you fine control of level, for better pinpointing of uneven patches of flooring. The idea behind the GSL 2 is simple, but ingenious: it projects two angled beams along the surface of your floor. Where the floor is flat, the beams will intersect exactly on the surface, showing up as a single line. However, where the floor dips or rises, the beams will separate into two clearly discernible lines, showing you precisely where the uneven patch begins & ends.Features and BenefitsHandy remote control for indoor use with a range of 20 mThree control speeds for fast, slow and step-by-step movementAppropriate for GSL 2 ProfessionalSpecificationsRange: 30 mPower supply: 3 x 1.5 V LR03 (AAA) Dust and splash protection: IP 5X Weight, approx: 69gIncludes:3 x 1.5 V LR03 (AAA) batteries
