Explore this buying guide ↗Why consider this model?
- A legacy M12-powered wall-scanner configuration when its documented 1.5-inch Stud-mode ceiling, center/edge cues and exact battery/package state meet the job; it is not presented as a currently available product.
Tradeoffs to weigh
- Milwaukee marks the exact configuration no longer available. The 6-inch concrete-metal mode is not stud depth, the 2291 source set documents no live-wire meter, and wall construction can affect readings. Battery and charger must be checked separately; Milwaukee lists only tool and manual in the bare-tool box.
