The green color of the laser beam is clearly visible even in difficult conditions e.g. In rooms with visibility impaired by dust. The long working range even without a detector emphasizes the usefulness of the device. Battery power increases the comfort of use.another device is a laser rangefinder which displays measurements in m in and ft units. The rangefinder has 2 reference points - front and base - thanks to which the operator has greater freedom of work. The tool is equipped with many functions that improve work such as volume and area measurement continuous measurement addition and subtraction 4 trigonometric calculation modes and the ability to calibrate within the range of ±9 mm which allows for maintaining consistent measurement precision. Everything is displayed on a clear lcd screen. The built-in bubble expands the range of applications.product features:ability to precisely lay tiles and floors and install suspended ceilings among other things.green laser beam for better visibility in difficult conditions.the long laser range allows you to work in larger rooms.2 rangefinder reference points for greater work comfort.the rangefinder has many built-in functions that improve work efficiency.the clear lcd display minimizes reading errors.the built-in bubble expands the range of applications.convenient battery powering.cross-line laser.magnetic laser holder.2 aa batteries for the laser.rangefinder.reflective plate.2 aa batteries for the rangefinder.user's manual.**illustrative photos.
