Overview
The Franklin Sensors ProSensor 710+ is an electronic wall scanner built around 13 sensors that light up across an LED display to show the full width of a wood or metal stud, rather than just a single point.
Where most stud finders rely on one or two sensors and require the user to start scanning from a spot known to be clear of a stud, the 710+ is built to be pressed and held anywhere on the wall. Franklin markets the 13-sensor array as the reason for that flexibility, since a wider sensing strip reads the whole stud instead of guessing from one edge.
- 13-sensor wide-array scanning
- Always-on deep scan to about 1.6 inches
- Built-in bubble level and ruler
- Reads both wood and metal studs
Who it's for
Homeowners and contractors hanging TVs, cabinets or shelving who want to see a stud's full width and center rather than a single beep. Less suited to anyone who wants live wire detection built in, which this model does not list.
Strengths and trade-offs
Drawn from this product's published specifications.
- Shows full stud width, not a single point
- No calibration needed, can start over a stud
- Built-in bubble level and ruler
- Detects both wood and metal studs
- Batteries required but not included
- Not compatible with rechargeable batteries
- No live wire detection mentioned
Performance notes
The 13 sensors read a wider strip of wall at once, so the LED display can show a stud's full width and mark its center in green rather than a single point of contact. There is no calibration step; pressing and holding the button starts scanning immediately, even directly over a stud. The deep-scan mode stays on at all times and is rated to sense up to about 1.6 inches into the wall, covering both wood and metal studs.
