PLUMB ONE ±0.1° · 12 M 123456 FIG. 02 — PLUMB ONE, 86 G, 96 × 42 × 18 MM
01 / Anatomy

Six parts. Each one earns its place.

We removed everything that did not help you draw or trust a line.

1

Laser window

A visible laser diode behind a ceramic ring. The ring glows lime when level and coral when it is not.

2

Vial display

A real bubble you can read without power, mirrored on your phone for a second opinion.

3

Mode button

One tap for line, two for cross-line, hold for the phone link. That is the entire interface.

4

Magnet back

Rare-earth magnet with a soft rubber face. Holds to studs and steel without marking them.

5

USB-C port

Charges in 90 minutes and runs for 40 hours of beam time. Works from any power bank.

6

Pin-tab slot

Slide in a pin tab to hold Plumb on drywall with a hole smaller than a sewing needle.

02 / Accuracy

Why 0.1° matters at 12 metres.

A degree sounds small until you stretch it across a room. Drag the sliders to compare.
