Some popular questions about line laser detectors

Line Laser Detectors (Receivers)

Line Laser Detectors have been around for some time now.  They allow a suitable laser line to be picked by the electronic detector  / receiver much the same as a rotating laser beam can be picked up by a rotating laser detector / receiver.

There are a few things you may not know.

  1. Will a Line detector pick up any line laser’s line.  No is the quick answer.  Going back to a rotating laser and receiver, a rotating dot passes over the sensors on the rotating laser detector every revolution so creating a pulse of laser energy the detector picks up this pulse and so tell you where the laser is. With most line lasers there is no pulse, its a solid line and line detectors work in a similar fashion to rotating detectors they need a pulled laser to be able to work.  So some line lasers have a pulse mode, sometimes, this is permanently turned on and others its a switchable mode.  If your line laser does not have pulse you will not be able to buy a line detector to work with it.  No the pulse of a line laser is extremely fast and so is not detectable by the human eye so don’t expect to see a flashing line.  (flashing line often mean something completely different such as the laser is out of self levelling range)
  2. Can I use a rotating laser detector on my pulsed line laser?  Again no. Line detectors pick up a different frequency of pulse compared to that of a rotating laser and so are not compatible.
  3. Can I use any brand line receiver on any brand pulsed line laser? This is a tougher question, and the answer is not definitive. Yes sometimes you can mix and match brands on line receiver to line lasers and sometimes you cannot.
  4. Can I use a red line detector on a green pulsed line laser? Again not strait forward most of the time you cannot but sometimes it will work but at reduced range.  So my advice is if you can use the receiver / detector that is designed for the laser you are using.
  5. Why would you want to use a detector / receiver anyway?  Inside in dull conditions you can see a good quality line laser visibly over many meters 10 or 20 or so, with green beams may be up to 30m but outside in full sun its a completely different kettle of fish.  Even the legally brightest of lasers (class 3 and green beam) you will not see visibly over more than a handful of meters in full sun.  This is where a line laser detector comes into its own, it sees the laser for you and indicates its position to you, whatever the lighting conditions often 50 or 60 meters depending on brands and models.
