Can’t find speaker wires behind drywall
My home was prewired for in-wall speakers. I had a rough drawing from the contractor on where the speaker wires were located in ceiling. I found one wire end in the attic, and bought this tone generator/pulse thinking I could find where the wires terminated before cutting holes in the dry wall. Fat chance. The only time I could get a tone is was near the exposed wire in the attic. As soon as I tried to use the probe through the drywall, got nothing but static, even just 6-inches from where the wires dropped out of the attic. Spend the money to get a tool that works. This one doesn’t.
