What’s the difference between red beam and green beam?

The reason for opting for a red beam or green beam depends on your budget or requirements. Whilst red beam lasers are designed for both exterior and interior applications and get the job done to a satisfactory level, they are much more affordable option owing to the ease-of-use and precision of the green beam laser. The colour green is closer to the centre of the visible spectrum, thus making it up to 400% more visible to the naked eye and therefore perfect for exterior and interior jobs such as suspended ceilings, curtain walling and partitioning.

Can I use the laser outside?

Working outside with a laser can be challenging without the correct instrument or accessories. The Datum Constructor has rotary and line lasers and includes red or green beam glasses as well as a Datum LS-8 Laser Detector, ensuring that you can comfortably use the laser over long distances with a clear vision of the laser beam. The supplied tripod and staff also enables surveyors to take outdoor measurements with ease and precision.

What does the IP54 rating mean?

IP stands for ‘Ingress Protection,’ which is an international standard rating system used to define how effective the sealing of level or electrical enclosures are against intrusion from dirt, dust, moisture or water. The first digit rates its protection against dirt and dust, the Datum Constructor Laser Level has a ‘5’, an impressively high rating, which means that it is dust protected with minimal dust intrusion. The second digit represents its water resistance; the Datum Constructor Laser Level has a rating of 4, which means it is protected from water sprayed in all directions.

Can the laser light hurt my eyes?

It is advised that users should never stare directly at a laser beam for a prolonged period of time.
