Point lasers project dots instead of lines. They're built for transferring points between floor and ceiling, plumbing walls, and aligning fixtures vertically and horizontally. The Bosch GPL5 and DeWalt DW085K both project 5 dots: up, down, left, right, and forward. Both self-level. Both run on AA batteries. The differences are subtle: accuracy tolerance, dot brightness, and housing durability.
Quick Verdict
The Bosch GPL5 is more accurate. When you're plumbing a wall or transferring a floor point to the ceiling for electrical box layout, the tighter tolerance means your holes line up the first time. The DeWalt DW085K is $30 cheaper and includes a magnetic mount and a hard case. For rough layout work where 1/4-inch tolerance is acceptable, the DeWalt saves money without sacrificing function.
1/32-inch accuracy at 30 ft puts ceiling boxes directly above floor marks. The DeWalt could be off by 1/8 inch.
$30 cheaper and 1/4-inch accuracy at 100 ft is more than enough for stud alignment. Magnetic mount sticks to metal tracks.
When upper cabinets need to align with lower cabinets across a 12-foot wall, the tighter accuracy prevents cumulative drift.
Hard case, magnetic mount, and $99 price point make it the practical choice for occasional alignment tasks.

Bosch GPL5
Price: $129 (Amazon)
Pros
- 1/32-inch accuracy at 30 ft is the tightest tolerance in the consumer point laser class
- IP54 rating means it survives dust storms on a jobsite and a splash of water
- 0.46 lb is light enough to forget about when clipped to your belt
Cons
- Dots wash out past 50 ft in bright ambient light, despite the 100 ft spec
- $129 is premium pricing for a point laser
- No pulse mode for use with an electronic detector outdoors
DeWalt DW085K
Price: $99 (Home Depot)
Pros
- $30 cheaper than the Bosch for the same 5-point dot pattern
- Hard-sided kit case protects the laser through years of truck bed abuse
- Built-in magnetic mount sticks to metal studs and framing brackets
Cons
- 1/4-inch accuracy at 100 ft is noticeably looser than the Bosch spec
- 4-degree self-leveling range is 1 degree tighter, less forgiving on uneven surfaces
- 0.77 lb is heavier, though still light by any tool standard

Frequently Asked Questions
When would I use a point laser instead of a line laser?
Point lasers are better for transferring single reference points: floor to ceiling, wall to wall, plumbing verticals. Line lasers are better for continuous alignment like tile layout, cabinet runs, and framing level checks. Many pros carry both.
Can I use these lasers outdoors?
Both are rated for interior use. The red laser dots become invisible past 20 to 30 ft in direct sunlight. Neither has a pulse mode for use with an electronic detector. For outdoor layout, look for a green beam laser or a rotary laser with a detector.
How long do the batteries last?
The Bosch runs about 15 hours on 2 AA batteries. The DeWalt runs about 20 hours on the same. Both are efficient enough that battery life isn't a practical concern. A single set of batteries covers most multi-day projects.
