Laser level tool can not only be used as a level to check the accuracy of 0°, 45° or 90° directions, but also can be used as a ruler to measure the length of objects up to 17 feet long; It's perfectly suitable for any situation that requires a straight line or accurate measurement. Features: MULTIFUNCTION LASER LEVEL: Using the latest measurement technology, this laser level is more accurate and safer and it has 2 Laser emitting heads,no need to adjust the head to point cross line making it easier to use. 4 in 1 ADVANCED MEASUREMENT ACCURACY LEVEL TOOL: This multipurpose line-level laser measurement tool equips 3 modes of laser level, 0-degree, 45-degree and 90-degree bubbles, 10FT/3meter measure tape and 6.7in/17cm ruler, class 2 laser grade, power output<1mW, ≤3.5mm line accuracy. EASY TO OPERATE AND CARRY: Different from other multifunctional laser instruments, this one is designed with two laser heads and one on-off button to switch laser mode. Press the button once to horizontal laser, twice to vertical laser line, three times to cross laser line. 10 FT/3 Meter MEASURING TAPE: This laser level is equipped with a 10FT/3meter measuring tape ruler that includes both imperial and metric linear measurements with scales up to 1/32 "and 1mm. WIDE APPLICATION: Laser level tool works for indoor, designed for any situation where accurate measurements are needed, such as hang shelves, cabinets, tiles and picture frames with accuracy.
