A 9-sensor, 15-LED electronic stud finder with a manufacturer-stated 1.5-inch maximum, green center indicator and dedicated live-wire meter. Its exact manual describes a held-button, no-calibration routine and cautions that the signals report changes, not the identity of hidden objects.

Explore this buying guide ↗Why consider this model?
- A candidate for dry interior drywall when a buyer wants a green center cue and a documented live-wire meter in addition to an LED span, while a 1.5-inch stated maximum is sufficient as a comparison limit and the warning is not mistaken for safety clearance.
Tradeoffs to weigh
- The M155 combines a dedicated live-wire warning with 9 sensors, 15 LEDs, a green center indication and a 1.5-inch maximum. The meter does not identify every wire or make drilling safe, and the exact manual does not provide a usable lath-and-plaster plan; its package contents, SKU and battery inclusion are unconfirmed.
