Why consider this model?

  • A simple choice when the job is limited to locating stud edges on a dry interior drywall wall and you are comfortable marking both sides yourself.

Tradeoffs to weigh

  • It provides an edge cue rather than an electronic center or edge-and-center readout, publishes no separate live-AC warning, and requires the manual's calibration hold and a 9-volt battery.
