Stanley STHT77406 Stud Sensor 200 Stud Finder

The Stanley STHT77406 Stud Sensor 200 locates wood and metal studs behind walls before you drill, cut or mount. It detects studs up to 3/4 in. deep and senses live AC wiring up to 2 in. deep, helping you avoid energized wires. Center-find tells you when you are over the middle of the stud, and an LCD display with audible signal makes readings easy to follow. The sensor runs on a 9V battery. It is a helpful first step before mounting shelves, hanging cabinets, cutting openings or drilling through walls, giving you more confidence about what is behind the surface. Always follow the instructions supplied with the tool, and treat any AC indication as live until the circuit is confirmed off.

Stanley STHT77406 – Frequently Asked Questions

1) How deep will the Stanley Stud Sensor 200 find studs behind drywall?
The STHT77406 Stud Sensor 200 reads wood and metal studs to 3/4 in. deep. That covers standard 1/2 in. drywall and 5/8 in. type X board, so it works on most finished commercial and residential partitions. Thicker build-ups, plaster over lath, or drywall with a layer of tile or paneling over it can push the framing past the 3/4 in. limit, and then the sensor will not pick it up.
2) Will a stud finder tell me if there is live wiring behind the wall before I drill?
The Stud Sensor 200 senses live AC wiring to 2 in. deep and alerts on the LCD plus an audible signal. It only reads energized conductors, so a circuit that is switched off, a dead run, or low voltage cable will not register. Treat any AC indication as live until you have confirmed the breaker is off, and do not treat a silent reading as proof the wall is clear.
3) Does the Stanley Stud Sensor 200 mark the middle of the stud or just the edges?
Center-find is built in, so the tool tells you when you are over the middle of the stud rather than making you sweep both edges and split the difference. That matters when you are mounting a TV bracket or a cabinet rail and need the lag screw in the meat of the framing, not near an edge where it can split out.
4) Can this stud finder locate metal studs in a commercial steel-framed wall?
Yes. The Stud Sensor 200 detects both wood and metal studs at up to 3/4 in. depth, so it works on light gauge steel framing as well as wood. Useful for MRO and property maintenance crews working across buildings with a mix of wood partitions and steel stud construction.
5) Is the Stanley Stud Sensor 200 a rebar or pipe locator too?
No. The STHT77406 is a handheld wall scanner for framing and live AC wire, not a concrete scanner. It reads studs to 3/4 in. and energized AC to 2 in., which is not deep enough for rebar in a slab or buried conduit in masonry. For anything behind concrete you want a dedicated concrete or rebar scanner.
6) What battery does the Stanley STHT77406 take, and is one included?
It runs on a single standard 9V battery, the common rectangular type you can restock anywhere. Keep a spare in the bag; scanning accuracy on any capacitive sensor degrades as the cell drops.
7) What is the correct Stanley part number to order for the Stud Sensor 200?
Order model STHT77406. That is the Stanley Stud Sensor 200 with stud detection, live AC wire sensing, center-find and an LCD with audible alert. There is one configuration, so no finish, size, or option suffix to specify.
