The Spectra RC402N full-function remote control is standard with the Spectra GL412N Laser and offers an easy to use menu-driven interface. The radio remote operates at a range up to 330 feet (100 meters) and provides the ability to make grade changes and start automatic alignments remotely, which can significantly reduce setup time.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">Available with 4 different digital receivers, including the combo CR700 magnetic boom receiver and optional remote controls, the Spectra Precision GL412Noffers Spectra&#8217;s advanced leveling features that include automatic Grade Match, PlaneLok, Axis Masking and Fingerprint receiver pairing. The GL412N also lies on its side in the vertical position to perform manually levelled vertical and line alignment. <\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">Grade Match measures and displays the existing grade over unknown ground. As a consequence it eliminates time consuming and error prone calculations.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">PlaneLok automatically locks on to an existing horizontal elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather.<\/span><br \/>\n<span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">The unique \u201cFingerprint\u201d function only accepts the beam from the laser it is paired with.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">The Spectra <strong>GL412N<\/strong> can also be paired with the new Laser Remote App for Android smartphones, where your phone can be used as the remote control.<\/span><br \/>\n<span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">This package also features the ST805 transmitter that enables an increased remote control range from your phone to the laser.<\/span><\/p>\n<p><iframe title=\"Spectra Precision Horizontal Laser GL412N Self Leveling Grade Laser Hands On Training\" width=\"1170\" height=\"878\" src=\"https:\/\/www.youtube.com\/embed\/8TpQea9A8ag?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14px;\">Le <strong>GL412N<\/strong> is a single grade laser that also offers long-range operation in addition to its grade capability of -10 to +15 percent.
