Why consider this model?

  • A documentary candidate for ordinary dry interior walls when a 1.5-inch stated maximum is sufficient and a nine-light center/edge display is useful. Its sources do not document a dedicated live-wire meter or identify an M90 green center light.

Tradeoffs to weigh

  • The M90 provides nine sensors and nine LEDs at a 1.5-inch stated maximum; that display count is lower than the 15-light M150 despite both having nine sensors. Lath-and-plaster use is qualified, difficult surfaces are not guaranteed, and a meter, exact green-center cue, package contents and included batteries are not established.
