The GEKO cross-line laser 7159770 projects a continuous 360° horizontal line together with a vertical line to support accurate leveling and alignment tasks. The unit offers three operating modes — vertical, horizontal and combined 360° — and a locking function for setting angled reference lines. With a working range of approximately 20–25 m and an accuracy of ±3 mm at 10 m, this battery-powered tool is intended for indoor and limited outdoor applications. The package includes a carry case and a 1/4" tripod mounting thread for attachment to standard tripods or holders.
Advantages
The GEKO 7159770 delivers both a full 360° horizontal reference and a vertical plumb line using a single compact housing, reducing the need to move the device during layout work. Its three-mode selection and locking function provide flexibility for a variety of alignment tasks. Battery operation using four AA cells enables cordless use where mains power is not available, and the 1/4" tripod mount and carry case improve portability and setup options.
Suitable for
- Interior leveling and alignment for suspended ceilings, partition walls and tiling
- Transferring reference heights around a room using the 360° horizontal line
- Aligning vertical elements such as door frames, window frames and studs
- Light to medium renovation and installation tasks where a compact laser tool is preferred
When it may not be suitable
This cross-line laser is designed primarily for indoor use and short-range outdoor work; its specified working range of 20–25 m and visible laser output may be insufficient for long-distance exterior surveying or bright daylight operation without a detector. The accuracy of ±3 mm/10 m is appropriate for many construction and finishing tasks but may not meet requirements for high-precision engineering measurements.
Key specifications
- Laser lines: full 360° horizontal line and one vertical line
- Operating modes: vertical, horizontal, combined 360°
- Working range: approximately 20–25 meters
- Accuracy: ±3 mm at 10 meters
- Power supply: 4 × 1.5 V AA batteries
- Mounting: standard 1/4" tripod thread
- Included accessories: carry case
How to use
Place the laser on a flat surface or attach it to a standard tripod using the 1/4" mounting thread. Insert four 1.5 V AA batteries and switch the unit to the desired mode: horizontal, vertical or combined 360°. Allow the device to self-level if it has an automatic leveling feature, or engage the manual lock to project angled lines. Use the projected 360° horizontal line to transfer level references around the room and the vertical line for plumb alignment. Turn off the laser when not in use to conserve battery life and store it in the carry case for transport.
What to consider before purchase
- Intended usage area: primarily indoor and short-range outdoor applications up to ~25 m
- Required accuracy: ±3 mm/10 m suits many finishing jobs but verify for precision-critical tasks
- Power source: requires 4 × AA batteries — consider rechargeable cells for ongoing use
- Accessories: includes a carry case and 1/4" tripod mount; a laser detector or dedicated tripod is not included
Usage recommendations
For best results, use the GEKO 7159770 in moderate lighting conditions or with a suitable detector for increased visibility outdoors, mount the unit on a stable tripod for repeatable setups, and carry spare batteries or rechargeable AA cells to avoid interruptions during work.
