## Overview

The BOSCH GLL30 is a compact, battery-powered self-leveling cross-line laser that projects bright, accurate lines up to 30 feet with ±5/16 inch precision. Featuring a versatile 360° flexible mounting device and automatic leveling, it’s designed for quick, reliable setup on multiple surfaces. Ideal for professionals seeking portable, precise alignment tools, it includes 2 AA batteries and a one-year warranty with registration.

## Description

The Bosch GLL50-20 Self-Leveling Cross-Line Laser features a 50 feet range and cross-line mode that projects both horizontal and vertical red lines, allowing for leveling with a 5/16 inch accuracy at 30 feet. With its power flexibility, operate using the included AA batteries or purchase Bosch's 3.7V Lithium-Ion 1.0 Ah Battery (sold separately) that allows use of the tool while charging to diminish downtime. Its ergonomic, compact, lightweight design and IP55 dust- and water-resistant rating provide for both comfortable and dependable operation. The full rubber overmold housing helps protect every major impact point, acting like a roll cage for safeguarding. Equipped with a Smart Pendulum System, the tool self levels, will indicate any out-of-level condition by blinking and then locks when switched off for secure transport. Simply tilt the laser to use the lines at an angle with ease. Position the tool with the included integrated magnetic mount or utilize the 1/4 inch threading mount that fits with like-sized tripods.

Review: Great tool for DIY'ers. - I bought this as a gift for a family member. All I can say is that it much appreciated and I was told it works great and makes jobs faster and easier.
Review: Do Not Try to Wallpaper Without It! - I bought this level to help me install wallpaper. It took a bit of practice, but once I understood how to use it, it was very simple and extremely helpful. The level has an adjustable clamp which allows you to mount it on almost anything (I’ve mounted it on a wooden stair railing, a step ladder, etc.). If the red lines don’t show on the wall, it’s because you don’t have the level *ahem* level. If the lines don’t show, it’s not broken, it’s user error. The lines are clear and crisp and allowed me to get a perfectly plumb line every time. The wallpaper I installed has a very intricate pattern, so matching the seams had to be flawless. By using this level, every seam was flawless, even the 12-foot long wall!

## Features

- POWER FLEXIBILITY: The laser works with two AA batteries (included) or Bosch's 3.7V Lithium-Ion 1.0 Ah battery (sold separately), for less downtime on the job.

- ACCURACY: The laser has bright, thin lines that level within 5/16 inch accuract at 30 feet.
- SELF-LEVELING- The smart pendulum system self levels and indicates out-of-level condition by blinking and locks when switched off for secure transport.
- EASY-TO-USE: The laser is egonomic, compact and lightweight for easy use and storage.
- CLASS II LASER: 630 - 650 nm; <5 mW

## Questions & Answers

**Q: Can this be used to level a subfloor?**
A: Thank you for your question and interest with our GLL 3 Self-Leveling Cross-Line Laser. This is meant for aligning and not leveling. We highly suggest our GSL 2 Surface Laser designed for determining flatness and level of flooring. https://www.boschtools.com/us/en/boschtools-ocs/line-lasers-gsl-2-37290-p/ For further assistance you may visit our website: https://www.boschtools.com/us/en/ or you may contact us on 1-877-BOSCH99 (1-877-267-2499).

**Q: Does the laser level need to be at the same level as the line it is projecting, or can I project a line 8 feet high on a vertical 4x4 post?**
A: The GLL 30 Line Laser can be positioned or mount using a positioning device even higher as long as it is level. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

**Q: Can I use this level to determin if the floor in a room has settled on one side compared to the other?**
A: Thank you for your question. The GLL 30 Self Leveling Cross Line Laser does the job for leveling and other alignment tasks, like cabinets. For your application, I recommend using a leveling surface laser level, like the GSL 2. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

**Q: Can this be “locked” in and used at a 2 degree angle (1/4” per foot slope for plumbing) or will it only work at angles 4 degrees and above ?**
A: No it cannot. The product description is innaccurate. The GLL 50 has a lock/unlock switch for manual mode, this (GLL 30) does not.

### ⭐⭐⭐⭐ Ok for the price
*by L***T on January 10, 2026*

This works ok for the price. But you need either a tripod or something to set it in as its not adjustable at all. And ince you try to tilt it too far up it won't level itself any more.
