Why consider this model?

  • A considered choice for dry interior drywall when a buyer wants edge indications, a separate deeper scan mode and an added live-wire warning.

Tradeoffs to weigh

  • The A100 does not indicate the stud center, has no dedicated metal or AC scan mode, and is not recommended for lath and plaster; its deeper mode and WireWarning both have strict limits.
