Why consider this model?

  • A legacy Milwaukee scanner for a user who can verify an actual 2290-20 bare tool, has a compatible M12 battery plan, and wants a documented 1.5-inch Stud-mode ceiling with both edge and center cues plus an AC-voltage warning indicator.

Tradeoffs to weigh

  • The tool is an earlier generation and the bare-tool box list is sparse; its 6-inch Metal-mode figure is not stud depth, and plaster, mesh, dampness, variable density and the AC indicator's limits matter. A live-wire symbol is not a safety clearance.
