When asking yourself the question, "What laser level is best for my job?", there are several issues which you should consider:
1. What accuracy do I require?
Laser Sonics sells rotating lasers which are capable of achieving accuracies between +/-0.74mm at 30m and +/-4.5mm at 30m.
Lasers at both ends of this range are perfectly adequate for the jobs for which they are intended.
In general, the greater the accuracy required, the greater the initial cost for the laser. A more accurate laser, however, may produce savings well in excess of the additional cost.
Talk with us regarding your requirements.
2. Do I require a visible beam?
Normally visible beam lasers are used for interior applications such as installing suspended ceilings. Having a visible beam means the contractor does not have to use a laser sensor which can be dropped and damaged doing such work.
However, if a laser sensor is used; visible beam lasers can be used outdoors as well.
We sell both visible and infrared laser beacons.
3. Do I require a self-levelling laser?
In deciding which laser may be best for you keep in mind that lasers beacons may rely on manual,
semi self-levelling or fully self-levelling technology. Manually Levelled Lasers rely on bubbles in level vials for levelling. The operator has to manually level the laser in both the X-axis and Y-axis and rely on the bubbles for accuracy. These lasers will continue to operate even if moved outside the set levelling area and are generally the least accurate of all lasers.
Semi Self-Levelling Lasers self-level within a range because they are equipped with a compensator that levels the instrument within that range. To get to that range, the laser is mechanically levelled by way of levelling screws at the base of the laser to bring either a circular bubble within a bull's eye, or to bring dual elongated bubbles in level vials within their range. These lasers are much more accurate than manual lasers and have a shut off feature if the laser is bumped or goes out of the self-levelling range. Most can achieve accuracies of at least +/-3mm at 30m.
Fully Self-Levelling Lasers. These lasers are equipped with electronic level vials and servo motors. The servo motors level the instrument electronically and, when it is level, the laser's rotating head starts spinning. These lasers are the easiest to use and are often the most accurate. Some of our lasers are equipped with an "elevation alert" shutoff feature that prevents the laser relevelling if the laser's elevation has altered by more than an acceptable amount.
4. What future needs may I have?
Some lasers provide additional features which may prove to be a real benefit in the future. For example, if you currently use a 3-4-5 triangle for set-out work it may pay you to purchase a laser which incorporates a split beam which provides a beam at 90 degrees to the rotating beam. Do you require grade occasionally? Do you need the laser to be absolutely waterproof?
How much utility does the laser tool being offered provide me? What are my primary requirements?
What is the payback time of the tool?
What characteristics separate one laser tool from other products?
Where and how fast will the laser be repaired?
Especially when working indoors, consider beam brightness. Whether working indoors or out, watch the stability of the beam when the laser is moved or vibrated. Consider the quality of the housing and the accessories.
