The app can be downloaded from the Apple App Store and the Google Play Store.
The app is available only for Android and iOS smartphones. Other operating systems are not supported. Supported Android devices: Bluetooth®-enabled smartphones from Android 6. Supported iOS devices: iPhone (from 5s). Tablets are not supported.
Go to the app settings to see which languages the app is available in.
The app can be connected to the GCL 2-50 C Professional and the GCL 2-50 CG Professional.
First, check that Bluetooth® is activated on both your tool and your smartphone and that the devices are within range. Neither of the devices must be connected to any other Bluetooth® device. In the app, you can tap on the Bluetooth® symbol to establish a connection between the laser and the smartphone. Please note that this connection must always be established via the app, not via the settings menu on your smartphone.
No. It can only control one tool at a time.
The typical range is approximately 10 m, depending on the on-site conditions (obstacles, sunlight, etc.). In optimum conditions, the range can be up to approximately 30 m.
If the tool has been connected to the app before, it will be automatically detected when it is reconnected as long as the app is open on the smartphone, Bluetooth® is activated on both devices and the devices are within range.

To use this function, the laser must be connected to the RM 3 rotating base. To do this, it must be inserted into the support rails on the rotating base so that the LED on the base indicates that both devices are successfully connected. The tool can now be rotated clockwise and anti-clockwise via your smartphone, and at three different speed settings.
This function allows you to select three different profiles:
1) Maximum laser visibility (reduces the battery runtime)
2) Balanced profile (average laser visibility, average battery runtime)
3) Maximum battery runtime (reduces the laser visibility)
Thanks to hands-free operation via your smartphone, you no longer have to worry about shaking the laser line when trying to make manual adjustments, meaning that you don't have to readjust the laser.
The green laser beam is particularly useful in bright working environments, such as near to a window, because its visibility is four times greater.
The point concentration of the laser beam means that the red laser points are extremely easy to see in any environment.
The closer the GCL 2-50 C / CG Professional is positioned to the reference point, the better. The shorter the distance between the tool and the reference point, the smaller the standard deviation of the plumb point. Depending on the version, the RM 2 Professional or RM 3 Professional that accompanies the tool will support you in this: Simply fit it on the GCL 2-50 C / CG Professional and position the plumb point on the reference point. You can adjust the laser lines precisely.
The app allows you to adjust the visibility of the laser beam. This means that you can, for example, minimise the laser brightness so that the battery runtime is increased.
The energy required to power the RM 3 Professional comes from the non-rechargeable batteries or lithium-ion rechargeable batteries in the line laser. An additional separate power supply is not required.
The app can of course be useful even without the motorised RM 3 Professional multifunctional mount. Although you cannot adjust the laser lines via a motorised base, you still have numerous other functions, such as hands-free control of the laser. You can easily select the laser lines via your smartphone, and activate or deactivate the receiver mode. You can also switch the laser beam on and off. This is particularly helpful if the laser is positioned somewhere that is hard to reach. You can also see handy status information about the laser directly on your screen.
