# Bosch GPL100-50G Five-Point Green Self-Leveling Laser

The Bosch GPL100-50G is a five-point green-beam self-leveling alignment laser for transferring level, plumb, 90-degree and grade points. Its integrated multipurpose mount and listed AA batteries and hard case make it a compact layout kit, but it projects points rather than cross-line laser lines.

## At a glance

- Five-point projection is described for transferring level, plumb, 90-degree and grade points. It is not presented as a cross-line model.
- The self-leveling pendulum indicates when the unit is out of level, and locks when switched off for transport.
- The integrated mount is described with magnets and a 1/4 in.-20 threaded mounting option, plus 360-degree rotation.
- The manufacturer claims the green beam is up to four times brighter than standard red beams and gives a visible distance up to 125 ft.

## Pros

- Point projection supports common alignment tasks without relying on a manual plumb bob.
- Integrated mounting options and rotation offer flexibility for positioning the laser.
- The included AA batteries and hard carry case mean the listed kit includes power cells and storage.

## Cons

- Point projection is less suited to buyers who specifically need continuous horizontal or vertical cross-line coverage.

## Customer feedback

Customer feedback highlights the green light's visibility, perceived quality, accuracy and compact size. Some feedback is mixed on dot placement and versatility. That distinction matters here because the product is a point-alignment laser, not a multifunction or cross-line unit. Aggregate ratings skew positive, but they do not explain individual experiences.
- Positive themes: Customers describe the green light as bright and easy to see, and mention quality, functionality, accuracy and compact size positively.
- Mixed feedback: Feedback is mixed on dot placement, including differing descriptions of the five-point output.
- Mixed feedback: Versatility receives mixed reactions, with some appreciating its self-leveling use and others noting it is not multifunctional.

## Frequently asked questions

### Does the GPL100-50G project cross-lines?
The supplied details describe five-point projection for alignment work, not continuous cross-line projection. Choose a cross-line model if you need wall or ceiling lines.
### What does the integrated mount support?
The manufacturer describes magnetic attachment and a 1/4 in.-20 threaded mount, with 360-degree rotation.
### What comes in the listed kit?
The listed contents are the GPL100-50G laser, an integrated multipurpose mount, two AA batteries and a hard carry case.
### How far is the beam visible?
The manufacturer states a total visible distance up to 125 ft. Actual visibility can depend on jobsite conditions.

## Offer details

- The stated visibility distance and comparative beam brightness are manufacturer claims and can vary with working conditions.
- The listing describes a five-point laser. Confirm that point projection meets the layout needs before buying, especially if continuous cross-lines are required.
