Anyone who buys their first rotating laser often wonders if the device itself is not enough. Indoors, it may be. But on a construction site outside, you can hardly measure anything without three things: a receiver, a tripod and a staff.
Receiver – the “eyes” of the laser outside
In daylight, the laser beam is invisible outdoors. An external receiver (also called a sensor or "beeper") picks up the beam and shows it with sound and arrows on the display:
- down arrow / fast beep – you are above the plane,
- up arrow / slow beep – you are below the plane,
- line / continuous tone – you are exactly on the plane.
Receivers usually have two accuracy modes: fine (± 1 mm) for final measurement and coarse (± 2 mm) for quick leveling. In addition, a digital receiver shows the deviation directly in millimeters , so you don't have to move the receiver up and down.
Important: the receiver must be designed for the beam color of your laser – for a red or green beam.
Tripod – stability is precision
The laser on the tripod will level itself, but if the tripod moves, the plane will move too. When choosing a tripod, consider the following:
- 5/8″ thread – standard for construction lasers,
- aluminum legs with spikes that can be driven into the ground,
- adjustable height – to get the plane over obstacles, such as formwork.
During construction, place the tripod outside the work area so that it is not obstructed by the wheel of a wheelbarrow or lath.
Telescopic staff – used for measuring
The leveling staff is a sliding rod with a millimeter scale to which you attach the receiver. The most commonly used is the 5 m telescopic staff : when folded, it is short enough for a car, and when extended, it will cover even deep excavations.
How to use it correctly:
- Keep the bar vertical – a tilted bar shows a higher value than it actually is,
- Fix the receiver with a holder (clamp) , not with your hand,
- Always read the scale on the same edge of the receiver.
