Why consider this model?

  • A legacy scanner kit when the exact 2290-21 package is intact and one listed M12 pack/charger/case is useful alongside a 1.5-inch Stud-mode ceiling, both edge and center cues and a limited AC-voltage warning.

Tradeoffs to weigh

  • The kit shares the bare 2290-20 scan engine rather than adding depth or a new mode. It is an older package, the catalog does not specify battery capacity, and metal-mode depth, surface warnings and AC-indicator limits are easy to misread.
