The Dewalt DCT419S1 12V MAX 1.5 Ah Cordless Lithium-Ion Handheld Wall Scanner Kit offers an easy way to help determine if embedded materials are present behind a wall. It features innovative sensing technologies that make it ideal for remodelers, installers, service technicians and maintenance personnel. With a sensing depth of up to 3 in., the wall scanner offers a pre-scan mapping mode that eliminates the need for you to calibrate or choose between settings. The initial pass over the wall surface processes all the embedded materials behind the wall, and when you reverse the scanning direction of the DCT419S1, the embedded materials detected behind the wall surface are displayed on the 3.5 in. color LCD screen.
  • Sensing technologies detect five classes of embedded materials - wood, ferrous metal, non-ferrous metal, plastic and unshielded live electric - behind wall surfaces up to 3 in. deep
  • Scans through multiple wall surfaces including drywall, plywood, concrete and ceramic tile
  • Automatic mapping feature processes all embedded materials simultaneously
  • 3.5 in. color LCD display improves visibility and communication of embedded material type and location
  • Tracking bar displays embedded material locations of entire mapped area up to 9.8 ft.

When? Really when?
You and your product sellers have been advertising this for months. WHEN CAN IT BE PURCHASED? Or stop the false advertising. I am buying something else.

Not your Dad's stud finder
Innovative tool that rolls easily and tracks well. Requires forward pass to scan and reverse pass to reveal studs, plastic, etc., but what an amazing image of studs, etc... Very easy to use, but wish it had a finger/ thumb pencil scribe to mark center of studs as you detect them. Unit is bulky compared to my Zircon that gave up the ghost which I could throw in a drawer or toolbox, not so with this tool.

Is there a video available showing this tool in action? i would like to see what all it actually shows in each mode. I saw a question that stated it showed studs in a wall clearly, however $300 is way too expensive for a stud finder. But if it scans and identifies what is behind the top layer making bidding remodels easier and more accurate, then it would be well worth it. thanks
