Why consider this model?

  • A straightforward shallow edge finder when an on-wall pointer is useful and estimating a midpoint between two edge marks is acceptable.

Tradeoffs to weigh

  • Only one shallow edge-finding mode is documented; it has no direct center cue, separate deep mode or documented WireWarning meter.
