Product description At levelsure our line team of engineers and designers have ourselves to developing a higher normative of applied tools for our customers. Main : ? . opalescent 360 ° level and rampant beams the user to project a laser reference line around the room to quickly establish level. . Self-leveling less than 3 seconds, laser wavelength is 510 ± 5nm, meet the line requirement. . IP54-water/debris resistive -LRB- very steady and not well-off to be broken -RRB-, it can be at dust environment and washed. . 2 full-time pulse -LRB- inside and open-air -RRB- that can be switched with a naive click of a button. . Lockable to protect the most alive component of the laser for well-off and sound transport. . firm case provided for unaddicted, sound storage with extra space for a mount -LRB- not included -RRB-. . insufficient battery indicator to obtuse the beam to indicate the batteries need replacing. . Have a squeaking cost-efficient, the indistinguishable as the as the illustrious brand, but a expert price for amazon buyer. : ? . Laser : Class 2 -LRB- IEC/EN60825 -1 / 2014 -RRB-, ? .
