Hi ! I bought the Stabilas LAR 250 earlier whit REC300 detector . Can I use the detector whit LAX 400 ? Sincerely Samuel


  • Posted by Laser Levels Online - Support on Thursday 8th of December 2016
    Hi Samuel,
    Thank you for your message.
    There are two distinct types of laser levels - Rotary and Cross Line and each have their own type of laser detector.
    Rotary laser detectors work by the laser dot skimming across the face of the detector at around 600rpm. This means that as long as you stick to red lasers and red detectors or green and green you can mix and match any make and model of rotary laser level with and detector. e.g Stabila Rotary and a Spectra Detector.
    Cross line lasers require a pulsed output mode which depending on the frequency of the pulse can only be picked up by a propitiatory cross line detector. As such you can only reliably use the exact cross line detector specified for your specific cross line laser. As such you will need to buy a Stabila "Cross Line Detector". It will not work with any Rotarty detector.
    I have a showroom here full of cross line lasers and cross line detectors form various brands. A Dewalt detector wont work with a Stanley laser, a Stabila detector wont work with a Fukuda etc... etc...
    Sometimes another brands detector may be very close in frequency to the laser you have and may initially appear to pick-up the beam but you tend to find if the "real" detector is designed to work over a range of 50m, that the other brand will work up to a couple of meters and then stop picking up.
    I hope this helps.

Does the Lax 400 cross level have a pendulum lock for safety in transit


  • Posted by Laser Levels Online - Support on Tuesday 23rd of August 2016

    Hi Ian,

    Yes, both the LAX300 and LAX400 both have a transit latch which locks the pendulum to one side when in transit.

    I hope this helps.

    If you have any further questions or require any additional assistance please do not hesitate to contact us.
