What is better with the new laser level? It is far more precise than conventional tool, to start with. Mid-range digital level measures to +/- 0.2mm precision while determining heights and for measuring distances, the accuracy is +/- 0.2% mm up to 100mtrs. Or take a rotary laser level used for concreting, grading and decking; this provides ±1.5mm/30m accuracy. All this was unthinkable just a few years ago.
The second way laser level has got better is the number of types. Browse website of any online survey supply store; there is a dizzying array of digital levels. The variety is so wide that selecting the right type may look daunting, but the upside is that there is always a devise to suit your purpose and well within the budget.
Here a word on the prices would be in order for a simple reason. Depending on the sophistication and the purpose it serves, a laser level may cost from $20 to $12,000 and above. Online survey supply stores offer anywhere between 20 to 50% discount on reputed and well-known brands. You can get an automatic green beam rotary for about $1,400, and save more than $800. On self-leveling cross line laser, online survey supply store allows a discount of about $150 and you can get the devise for about $250.
Keep the price factor in mind; it will surely help in saving some dollars.
The laser level is useful for checking levels, setting plumb, squaring operations, and aligning points. As such, setting gradient for laying pipes, grading construction sites, and pouring concrete are some of the tasks performed using digital levels. It is also useful in installing ceiling tiles or power receptacles, and drop ceilings. On agricultural lands, the level helps to set grade for proper drainage, aligning fences and decks and contour farming. And for surveying large areas, laser level is of course the preferred tool.
Survey supply stores usually stock four types of laser levels. Rotary laser levels shoot a rotating dot to create a 360º line, have both plumb up and down and can be used for most of the purposes already mentioned. Line laser levels project multiple laser lines, both horizontal and vertical, over a distance of 20-30m and are good for both indoor and outdoor measurements. Single line lasers, project only a single line, and are useful for short ranges. Point generating levels are like the spirit levels; shoot a laser dot as reference points. Professionals need auto-leveling levels, while small and indoor jobs can be done using manual levels.
So far, we have seen what is ‘better’ with laser levels; it is time to see what is the ‘less’ side. You require less workers; one person can accomplish the work of two or even three people and in less time. You will be saving something like 40% on most jobs.
And as already discussed, you know where a laser level costs less.
