Franklin Sensors Prosensor 710+ Review: Key Features & Specifications
The Franklin Sensors ProSensor 710+ is a multi-point stud finder that takes the guesswork out of locating studs behind walls. Unlike traditional stud finders that detect one point at a time and often give inconsistent readings, the Franklin ProSensor 710+ uses patented MultiScan Technology to simultaneously detect and display the full width of multiple studs at once through its 13 LED indicators.
Just press it against the wall and the LEDs instantly show you where the studs are — no setup, no guessing, no repeated scanning needed. On top of that, the Franklin ProSensor 710+ adds a built-in bubble level and AC wire detection, making it a step up from the base Franklin ProSensor 710 for anyone who needs a little more from their stud finder. Built for both DIY homeowners and professionals, it is one of the most straightforward and reliable stud finders on the market.
Key Features
13 Individual Sensors for Superior Accuracy
Unlike conventional stud finders that use a single sensor, the ProSensor 710+ scans thirteen locations simultaneously, ensuring every stud is correctly identified with far greater precision and far fewer false readings.
Triple Accuracy Technology
The device analyzes and triangulates data from all 13 sensors at once to pinpoint the exact location and full width of each stud — delivering consistently reliable results that single-sensor models simply cannot match.
One-Step Operation With No Calibration
Just place it on the wall and press the button, the LEDs instantly light up where the wall studs are. No sliding, no setup, no calibration needed before every use.
Detects Multiple Studs at Once
Powered by innovative stud sensing technology, the ProSensor 710+ instantly finds hidden studs and can detect up to two objects simultaneously across a full 7-inch scanning width in a single press.
1.6-Inch Detection Depth
The device automatically adjusts through one layer of drywall, scanning up to 1.6 inches deep for reliable readings across standard wall types and surfaces.
Wide LED Display Showing Full Stud Width
The 13 LED indicators display the complete width of the stud — both center and edges at once so you know exactly where to drill without any guesswork.
Center Stud Indicator
On certain models, the middle LED turns green to mark the exact center of the stud, giving you a precise drilling point with zero uncertainty.
Built-In Bubble Level
The ProSensor 710+ includes a built-in bubble level, making it a two-in-one tool that lets you find studs and ensure perfectly level installations without needing a separate level.
Built-In Ruler
An integrated ruler runs along the top edge of the device, allowing you to measure and mark stud locations on the spot without reaching for a separate tape measure.
Powered by AA Batteries
The ProSensor 710+ runs on two standard AA batteries which is more affordable and easier to find than the 9-volt batteries most other stud finders require. Note that rechargeable batteries are not compatible.

How We Tested the Franklin Sensors Prosensor 710+
Testing Setup
To make this test as close to real-world conditions as possible, we brought in a handyman to help build a dedicated mock wall from scratch. Inside the wall, spaced at standard 16-inch intervals, were wood studs alongside a range of materials you would commonly find hidden behind drywall in a real home:
Wood studs
Copper pipe
Gas line
Sewer pipe
Flexible ducting hose
Live electrical cable
Testing against all of these materials in a single controlled environment gave us a much more accurate and complete picture of what the ProSensor 710+ can and cannot do — far beyond what a standard stud-only test would reveal.
Performance Test Results
Wood Studs Detection
Observation
The ProSensor 710+ delivered a tight, well-defined reading right away. The LEDs lit up with precision, creating a clear and immediate picture of exactly where the stud started and where it ended.
Result
When it comes to detecting wood studs, the ProSensor 710+ is accurate and reliable. The results were clean, consistent, and easy to read at a glance.
Gas Line Detection
Observation
The Franklin Sensors ProSensor 710+ struggled here. It picked up the stud without issue, but as it moved over the metal gas line, the reading became inconsistent and unreliable. The LED spread was unusually wide and never settled into a defined result. It seemed to recognize that something was behind the wall but couldn’t determine exactly what or where.
Result
The Franklin Sensors ProSensor 710+ is not built for gas line detection. While it can sense that something is present, it cannot identify or precisely locate metal pipes making it an unreliable tool for this specific use case.
Sewer Pipe Detection
Observation
The Franklin ProSensor 710+ showed no reaction whatsoever. No LEDs lit up, no reading was generated. It simply did not detect the sewer pipe at all.
Result
Sewer pipe detection is completely outside the Franklin ProSensor 710’s capabilities. It was designed specifically for locating wood and metal studs, not pipes. If your project involves locating sewer lines behind walls, a dedicated pipe detector or multi-function wall scanner would be the right tool for the job.
Electrical Wire Detection
Observation
The Franklin Sensors ProSensor 710+ picked up the studs without any issue but showed no response to the electrical wiring. Even directly over the cable, there was no indication that any wiring was present behind the wall.
Result
The base Franklin Sensors ProSensor 710+ does not include AC wire detection and this test confirmed it. It will not warn you of live electrical cables, which is an important limitation to be aware of before drilling. If electrical wire detection is a priority for your project, the ProSensor 710+ or a multi-function wall scanner with built-in AC detection would be the safer and more suitable option.
Ducting Hose Detection
Observation
As the Franklin ProSensor 710+ moved across the wall, the LEDs responded actively and tracked the ducting hose as it passed over it. The reading was smooth, consistent, and easy to follow from one side to the other.
Result
The Franklin ProSensor 710+ handled ducting hose detection without any trouble. The LEDs gave a clear and accurate reading of the hose’s location behind the drywall.
Copper Pipe Detection
Observation
The Franklin ProSensor 710+ had no trouble picking up the stud on the right side but completely missed the copper pipe. There was no LED response over the pipe at any point during the test.
Result
Copper pipe detection is another area where the Franklin ProSensor 710+ falls short. It was not designed to locate copper pipes and the test confirmed that limitation clearly. If your project involves finding copper plumbing behind walls, a multi-function wall scanner with pipe detection capability would be the more appropriate tool to reach for.
