Source: boschtools.com (verified 2026-08-05) · corroborated by burnstools.com. Bosch's official D-TECT120 page confirms UWB radar Spot Detection technology, three modes (drywall/universal/concrete), calibration-free operation, detection depths (live copper wire 2-3/8 in., ferrous and non-ferrous metals 4-3/4 in.), and 4x AA battery power with optional 12V Li-ion compatibility. A Global Test Supply distributor listing notes the model as discontinued/replaced by the D-tect200C, but the machine remains actively sold at Burns Tools, Walmart, Amazon, and EngineerSupply as of the access date, so it is retained with Burns Tools' $419.00 price as the clearest current figure and the wider observed range noted.
