RoboToolz Crossliner Laser: Discontinued — What to Buy Instead

RoboToolz is defunct and the Crossliner line laser is not available.

How to read the accuracy spec

Laser levels are quoted as something like “±3mm at 10m”. That is the number that matters, and it scales — at 30m the same instrument is ±9mm. Before buying, work out the distance you actually work at and what error you can live with at that distance. For tiling a wall, almost anything will do. For setting out a suspended ceiling across a hall, it will not.

Self-levelling range is the second number. A pendulum self-levelling head corrects within a few degrees of level and locks out beyond that. Out-of-range is a feature, not a fault: a laser that cannot level should tell you, loudly, rather than project a line that is wrong.

Green versus red

This is the single biggest practical upgrade since the RoboToolz era. Green beams are perceived several times brighter than red at the same power, because the eye is most sensitive in that part of the spectrum. On a bright site, or across a long room, a red line vanishes and a green one does not.

Green diodes cost more and draw more current, so batteries last less time. It is worth it for anything but a dark interior.

The other thing that changed

Three-plane (360-degree) lasers. Instead of a cross on one wall, they lay a full horizontal plane around the room and two vertical planes. For setting out cabinets, floors or ceilings, that removes almost all of the repositioning that line lasers required.

Check it before you trust it

Any laser can be knocked out of calibration in transit. The field check: set the laser near a wall, mark the line, then move the laser to the opposite side of the room aimed at the same mark. If the two readings disagree by more than the spec, it needs calibration.

What to buy

The Bosch GLL3-330CG, linked below, is a green-beam three-plane laser — a full 360-degree horizontal plane plus two verticals. The green beam and the 360-degree planes are the two things that make a modern laser genuinely faster than a spirit level, rather than just more impressive.

For a single wall at arm’s length, a good 1200mm spirit level is more accurate, needs no batteries and costs far less.
