We have tested the SUB-SCANNER on wood lathe construction and it? does not consistently perform in this application.”
The Milwaukee SUB-SCANNER detects studs behind walls measuring the differences in? density. In a gypsum wallboard application, the SUB-SCANNER is first calibrated on the gypsum wall, then is moved across the wall and detects the wood studs running vertically. However in a wood lathe wall construction, the wood and plaster cannot be “calibrated out” because the plaster keys that are created between the wood lathes are not uniform.
What about the old lath-and-plaster walls used in pre-WW2? houses (like mine)? Will it still accurately find studs and wiring in that environment when there are so many more pieces of wood and nails present?
