The 44 Leica rows in this catalogue solve one job at three scales: establishing a reference plane. Indoors that job belongs to a line laser, on open ground to a rotating laser, and for a single distance to a laser meter. The tripod that carries the instrument, the staff that reads the plane and the detector that finds the beam are part of the same chain, and the range here is built to cover it end to end.

The Lino series is the line laser family for interior work. The L2 and L2s project one horizontal and one vertical line; the L2P5 and L2P5G add five plumb points to those lines; the P5 projects points only; the L6R and L6G project three 360° planes — one horizontal, two vertical — which sets out a whole room from a single setup. All of them share ±0.2 mm/m levelling accuracy, a ±4° self-levelling range and IP54 protection.

What the letters mean: a trailing G is the green beam, R the red, P5 the five point outputs, L6 the three-plane multi line layout. A lower case s marks the alkaline-powered version — the L2 and the L2s use the same optics and differ only in the power source. Li-ion versions run 28-44 hours and alkaline versions 8-25, and where there is no charging on site, swapping cells turns into the advantage.

The choice between red and green is not about output power but about the eye: green sits at the wavelength human vision is most sensitive to and reads distinctly brighter than red at the same output. On a floor with the lights on, or at distance, the green line stays readable while the red one washes out. Green models draw more power in return, and for short-range work in shade a red model is still the right choice.

The Rugby series is the open-site half. A rotating laser spins the beam at up to 10 rotations per second to establish a continuous grade plane, and that plane is read with a detector rather than by eye — which is why it works in daylight. The Rugby 610 levels horizontally at one button press; the 640 adds vertical levelling, a scan mode and plummets; the 680 gives digital dual-axis grade up to 8% and, at ±1.5 mm over 30 m, is the tightest of the three. Working diameter runs from 500 to 1100 m depending on the detector, and the bodies are rated IP67 from -20 to +50 °C.

On the DISTO side there are three ranges: 70 m with the Agatec Tape7, 100 m with the D2 and 300 m with the S910. The D2 sends readings to a phone over Bluetooth; the S910 is built for facade and as-built survey work, with point-to-point (P2P) measurement between two independent points from a single setup, a 360° tilt sensor, a 4x zoom camera and DXF export. The DST360 set makes the same work possible outdoors by aiming through the camera.

Accessories make up more than half the list, and they are usually the part that turns out to be missing. On tripods the first thing to check is the thread: 1/4″ is the fitting for line lasers and distance meters, 5/8″ for rotating lasers and levels. The TRI70, TRI120, TRI200 and RMT2111 are 1/4″; the RMT160, RMT220 and RMT300 are 5/8″ heavy duty — the RMT300 reaches a 290 cm working height, because the grade plane has to clear formwork and rebar.

The remaining accessories close the three weak points of a measurement. Target plates (GZM3, GZM26, 766560, the TPD100 set) keep the mark readable at the distance where the beam washes out on the surface. Detectors (the R250, and the RRC350G for green beams) find electronically the plane daylight hides. Staffs and the staff bubble (RMM05, RSS111, RMM07, RMM000) turn the plane into a number — and the bubble exposes the error a leaning staff quietly adds. Wall, formwork and ceiling brackets (A200, A220, UAL130, 758839) and the magnetic adapters (Twist250, Twist360) fix the instrument to the working surface itself where a tripod will not go.
