Grettz G4D vs DeWalt DCE089: 4×360 or 3×360?

The Grettz G4D and DeWalt DCE089 are both professional green multi-line lasers, but they make different trade-offs. This isn't a useful comparison if the conclusion is simply “ours wins”.

The biggest difference: four planes versus three

The G4D projects four 360° planes: two horizontal and two vertical. The DeWalt DCE089D1G18 projects three 360° planes. DeWalt's arrangement is already highly capable for room layout; the G4D's extra lower horizontal plane is the meaningful difference.

On the G4D that lower beam sits 9mm from the floor, which can be useful for floor tiling, low-level cabinetry and other work close to floor level.

Where DeWalt has a clear advantage

DeWalt's current DCE089D1G18 works with both 12V and 18V XR batteries. If your van is already full of DeWalt XR tools and batteries, that ecosystem convenience is a genuine reason to choose it.

DeWalt also specifies a 70m working range and 100m with its compatible detector, ±3mm accuracy at 10m, IP54 protection and 1m drop resistance.

Where G4D makes more sense

If you specifically want four planes and a horizontal reference very close to the floor, the G4D has a geometry advantage. It also uses USB-C rechargeable lithium-ion power and offers up to 18 hours of runtime, so it doesn't require ownership of a separate power-tool battery platform.

Detector use

Both systems support detector use in the appropriate mode. That matters when the visible line becomes difficult to locate, although neither should be confused with a receiver-based rotary system for long-range site levelling.

Which would we buy?

The bottom line

DeWalt is the obvious fit for some tradespeople, particularly existing XR users. G4D is compelling when the fourth plane and low floor line solve work you regularly do. Count the references you need rather than the logos on the case.
