Functions: NEW GREEN LED TECHNOLOGY - We adopt advanced technology, made in Germany, which is now the best green laser unit in the world; A green laser is 2 times brighter than a red laser with the same light source. Huepar 901CG has 15.3 m visibility under the cloud cover and a light intensity of 14,000 lux. 360 DEGREE HORIZONTAL LINE: Thanks to the ultra bright 360 degree horizontal green beams, the 901CG rotating laser provides all-round leveling coverage with an accuracy of ± 3m inch at 10m and a maximum working range of 45m, allowing you to work in different parts of a large room simultaneously. All of this allows 360-degree horizontal transfers, vertical transfers, and perpendiculars, inside and out, all with ease. MULTIFUNCTION MODES: One-button operation makes it much easier to project lines at once or independently as needed (transverse, vertical and 360-degree horizontal coverage). Press and hold the top button for 2 seconds to activate "SLOPE" mode which allows you to display straight lines in any position and at any angle. PULSE MODES: The full-time burst mode is useful by default with the optimal duty cycle rate modulated primarily for indoor applications when the tool is turned on for the first time. The laser beams are easily detected without noticing the slightest power scattering of the laser beam, which contributes to clarity / visibility. ROBUST AND USER-FRIENDLY CONSTRUCTIONS: The 901CG laser level is well-designed with a rubber cover, gaskets and seals in the housing to boast best-in-class reliability and high IP54 durability and the ability to maintain a straight row of six sides Drop from a height of 1 meter above the ground without loss of functionality and accuracy. Specifications: Laser class: class 2 (IEC / EN60825-1 / 2014) Leveling accuracy : ± 3 mm / 10 m Accuracy horizontal / vertical: ± 3 mm / 10 m Leveling / Compensation Range: 4 ° ± 1 ° Working distance (line): 45m (100 LUX) Working time: 4 ~ 6 hours with all laser beams on Power source: 4 × ˝AA˝ (LR6),> 1500 mA Items in the package: 1 X Huepar 901CG Laser Level (without battery) 1 X Magnetic Swivel Base 1 X Green Laser Target Card 1 X Fabric Pouch 1 X English User Manual 1 X Tripod Body 1 X 5/8 inch conversion screw 1 X Storage box - Self-leveling mode: Unlock the pendulum, self-leveling mode is on. The laser beam will flash continuously at 2 Hz when the tool is outside the self-leveling range (4 ° ± 1 °). - Manual mode: Lock the pendulum, you can （use a tripod or other bracket） position the laser tool at different angles to project uneven straight laser lines. You can display the cuts. The laser beam will flash every 3-5 seconds to remind you that it is not self-leveling now. - Three kinds of circuit switching functions: Each time the power button is pressed once, the laser tool projects the horizontal, vertical and transverse lines in sequence. 360 ° shield horizontal line and 360 ° vertical line (H360 ° / V360 °) The laser tool can help you more easily in interior decoration, partition wall construction, chandelier installation, drilling position alignment, stair railing installation, hanging photo projects, tiling, window construction etc. - Pulse mode ： Unlock the pendulum, press and hold the power button (about 5 seconds) to turn on pulse mode, then turn it on red. When outdoor work is required (receiver to be purchased separately, LR-5RG laser receiver can receive pulses). Characteristics: (1/4 "-20 screw quick release plate): 1/4" -20 screw quick release plate for quick device connection. Compatible with most rotating lasers, digital cameras, lenses, most cameras, GoPro devices, binoculars, telescopes, etc. (3-way flexible panoramic head): Provides 360-degree rotating panorama, allows you to rotate at any angle horizontally and vertically. The built-in spirit level can help you to adjust the angle and accuracy. (Adjustable 3 section legs and center column "): Buckle to adjust the height of three section legs, extended center column to meet different needs. Height range 0.2m-0.5m, load capacity 4kg. Net weight only 0.37 kg, light but durable. Easy to carry and transport in a storage bag. (Easy Operation): The movement of the tripod head is controlled by one positioning arm and a separate knob, which allows for vertical tilting of 90 °. You can easily adjust your working position without having to move the tripod. (High Quality Camera Tripod): Stable Camera Tripod is made of anodized aluminum tube (max size 16.7mm) and ABS environmental plastic, very durable. The center column and center braces are made of aluminum for extra stability.
