Has anyone used a heavy-duty scanner such as the Bosch Wallscanner D-tect 150? I guess Milwaukee makes something similar also. Or perhaps thermograghy? Fluke makes a nice thermal imaging handheld. Thanks. These tools are not cheap.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Kirk Herander<o:p></o:p></p><p class=MsoNormal>Vermont Solar Engineering<o:p></o:p></p><p class=MsoNormal>802.863.1202 fax 802.863.7908<o:p></o:p></p><p class=MsoNormal>VT RE Incentive Program Partner<o:p></o:p></p><p class=MsoNormal>NYSERDA Incentive-eligible Partner<o:p></o:p></p><p class=MsoNormal>NABCEP<sup>TM </sup>Certified Installer<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
