FAQ

Unilevel lasers are water and dust resistant. If the unit is caught in the rain, remove it from the weather and simply dry the laser off before it is stored. Most problems from water ingress occur when the laser is stored in its case when it is still wet. The laser will sweat in the case and moisture will work its way into the laser housing and can cause damage to the diode and circuits.

Electronic laser receivers are looking for a laser spot flashing across their photocells and will not respond to a stationary laser spot. That is why they can be set off by a flashing strobe or emergency beacon. Even if the receiver could pick up a stationary beam, the spot will be extremely difficult to find at any substantial distance from the laser.

Our lasers have fixed plumb spots that provide a 90 degree reference relative to the rotating beam when the laser is in its vertical mode.

The maximum power output for any construction laser is less than 5 milliwatts. A milliwatt is one thousandth of a watt. No special precautions need be taken with an invisible beam laser. Visible beam lasers should be set so they are not flashing in anyone's eyes because the light is very bright and can be annoying. Having the beam flash in one's eyes occasionally will not do any damage, but will be irritating in the same fashion as a camera flash.

Our lasers fit tripods with a 5/8 x 11 coarse thread. Flat or domed head tripods.

Almost any laser or survey instrument service center can calibrate our lasers. It is not recommended that the user do service or calibration work. Many of our authorised dealers around Australia have some service capabilities ranging from calibrating lasers up through full repairs. Please call our toll free number for your nearest service centre.

Most of the Unilevel lasers are operated with NiMh rechargeable batteries. The LS511, LS520 and LS521 can be operated with rechargeable or Alkaline batteries. We recommend the use of rechargeable batteries as they provide a similar run time to alkaline batteries and will provide hundreds of dollars of savings in battery costs over the life of the laser. In addition, NiMh batteries are less toxic to the environment and put less strain on our land fills.

Lasers should be calibrated when they are not shooting their specified accuracy. We suggest checking calibration regularly, at least every 6 months, or immediately if the unit has been treated roughly.

When paired with the LS705 receiver, most of the Unilevel range of rotating lasers have a 220m working diameter, and the LS521 has a 600m working diameter. Dot lasers and line lasers have a reduced working range as they are designed to be used indoors only, and without the use of a detector

A rotary laser will have to be used with a receiver outdoors in the sun. Sun light and visible laser beams tend to cancel each other out in sunlight which makes it impossible to see the rotating beam when outside. If you stop the rotating beam and shine it onto a shaded target, you can use it as a reference, but this is not that convenient.
