LockAngle Pro

LockAngle Pro

Digital Angle Gauge — available in two variants

Every measurement you've ever taken with a bubble level was a guess. This one isn't.

There's a particular kind of frustration that only tradespeople and serious DIYers know: you've done everything right, followed every step, and still the shelf sits at a slight tilt. The TV bracket is off by just enough to notice. The saw blade is close — but not right.

It happens because the tools we were given weren't built for the precision the job actually demands. A bubble level moves. A spirit level lies on uneven floors. An eye-read is always an estimate.

The LockAngle Pro exists to end that entirely. Both variants share the same precision-engineered core. The choice between them comes down to how and where you work.

How it works

At the heart of both variants is a calibrated digital inclinometer sensor that reads your surface to ±0.2° — a level of precision no bubble level can come close to. The moment you place it down, it locks onto the angle in real time. No squinting. No interpretation. Just a large, backlit LCD display showing you the exact number.

Both variants support absolute measurement mode — place it on any surface to instantly read the angle relative to horizontal — and relative measurement mode, where you zero the gauge to a reference surface and measure all subsequent surfaces against it. A single button press switches between degrees and percentage slope.

The Pro variant adds two capabilities that make a meaningful difference on complex jobs: magnetic grip on all four faces, so it holds firm regardless of the orientation of the surface you're working on; and a built-in bi-directional laser that projects a reference line across the full surface, letting you mark and confirm alignment from a distance.

Features on both variants

±0.2° precision 0.05° resolution — reads finer than any bubble level you've used.

Angle + slope modes Switch between degrees and percentage slope in a single button press.

Absolute + relative measurement Zero to any surface, then measure all others relative to it.

Data hold Freeze your reading on the display — no need to stay attached to the surface.

45-day battery life 2-hour USB-C charge; auto-rest after 30s, auto-off after 3 minutes.

Aluminium alloy frame Built for site conditions — compact at 6.2 cm x 6 cm (2.4" x 2.4").

Backlit LCD display Clear in direct sunlight and low-light conditions alike.

Exclusive to the Pro variant

4-side magnetic grip Attaches on any face — holds firm on vertical steel, pipes, and angled corners.

Bi-directional laser Projects your reference line left, right, or both — across the full surface.

Built for professional use

The aluminium alloy frame is not decorative. It is there because a tool that gets knocked off a scaffold, dropped in a van, or banged against steel beams needs to hold its calibration. Both variants share the same rugged housing.

The large backlit LCD display reads clearly in direct sunlight and low-light conditions alike. There is no fumbling with settings — it powers on in an instant, and the data-hold function freezes your reading so you can write it down or relay it without the gauge still being attached to the surface.
