Connectivity provides better results

  • Compact and versatile for all long-distance leveling applications
  • Contact-free control of the device and multifunctional mount
  • Dual power supply using lithium-ion rechargeable battery or standard alkaline-battery
  • GCL 2-50 CG Professional: Four times more visible thanks to green laser lines

The GCL 2-50 C Professional and GCL 2-50 CG Professional combi lasers are now available for simple leveling applications at distances of up to 50 m. They are the first combi lasers worldwide which can be controlled via app and Bluetooth interface. With this innovation, Bosch is continuing to expand the possibilities of connected measuring tools and offering tradespeople two new devices which optimize working procedures and increase productivity.

Bluetooth interface for increased precision

For example, the laser lines and plumb points can be switched on and off individually using the new Bosch Leveling Remote App. Each combi laser projects both a vertical and a horizontal laser line onto the wall as well as a centered plumb point on the floor and ceiling. Operating via the app ensures that settings are not accidentally altered when handling the device. Additionally, the combi laser can now also be set up in places which are hard to reach, or where it would be difficult to make precise adjustments to the position of the device. Thereby, work on construction sites is made faster and results are more precise. Moreover, users can adjust the brightness of the lines with the app, for example in order to make them more visible or to preserve battery life. The charge status of the battery and selected mode can also be seen directly in the app. The Bosch Leveling Remote App is available for free in the Google Play Store and in the Apple App Store, and is also part of the Bosch Toolbox App.

Remote-controlled motorized multifunctional mount

Users can work even more flexibly thanks to the RM 3 Professional multifunctional mount, which is motorized and can be controlled via app. Alternatively, the RC 2 Professional infrared remote control is also available. Both help tradespeople to align the combi laser with millimeter accuracy at three different speeds clockwise or counterclockwise. This is especially helpful if users are working at a distance from the device or on a ladder, as it allows them to control precision adjustments remotely. The power supply is provided automatically by the combi laser energy source as soon as the laser is inserted into the mount. Both devices are also available with the non-motorized RM 2 Professional mount, which is aligned manually. A variety of attachment options are available for the multifunctional mounts: They can easily be screwed onto drywall or wooden beams, their integrated magnets allow them to be attached to iron girders and other magnetic structural elements, or they can be secured to existing profiles in no time using a clamp.

GCL 2-50 CG Professional with green laser lines

The combi lasers differ in the color of the laser lines they project: The GCL 2-50 C Professional produces red laser lines, whereas the GCL 2-50 CG Professional uses a true green laser diode to project lines. The green laser lines are four times more visible, which is a real advantage when working in bright environments. In addition, the green laser diode is more powerful in comparison with devices that use color conversion from red diodes into green light. It also has a longer lifetime thanks to its lower operating temperature and is more compact.

Tried-and-tested functions such as the dual power supply

Both combi lasers are suitable for a variety of interior work tasks. This includes transferring plumb points for electrical installations or marking reference points, for example in order to place drywalls or for electrical sockets. Proven functions such as the tilt function for diagonal alignment – for installing handrails on staircases, for example – have been retained. The intuitive keypad makes operation easy and the device's leveling accuracy of ±0.3 millimeters per meter guarantees precise results. Both devices level themselves in less than four seconds and compensate for surface irregularities of up to ±4 degrees. They are powered either by a replaceable 12 V rechargeable battery from the professional range or with four AA non-rechargeable alkaline batteries together with the AA1 Professional battery adapter. The rechargeable battery is compatible with all 10.8 and 12 V professional tools from Bosch.

The GCL 2-50 C Professional and GCL 2-50 CG Professional combi lasers will be available from April 2017 onwards. All prices are recommended retail prices excluding VAT. Subject to change.
