How to choose
Sensor Array Capacity
The number of sensors significantly dictates the accuracy and speed of your scan. Franklin Sensors models utilize multi-sensor arrays, such as the 13-sensor ProSensor MAX or the 8-sensor ProSensor T9. These designs allow the device to detect both wood and metal studs simultaneously across a wider area compared to single-sensor units. When choosing a stud finder, consider whether you need a high-density sensor array for professional efficiency or a standard edge-finding sensor for basic home projects. Higher sensor counts generally provide a clearer visual representation of the stud's full width, reducing the likelihood of drilling mistakes behind drywall, plaster, or OSB surfaces.
Display and Interface
User interfaces vary between visual LED arrays and traditional LCD screens. The Franklin Sensors ProSensor series uses a row of LEDs to indicate the full width of the stud, which helps in identifying the center and edges intuitively. In contrast, the Zircon StudSensor Pro LCD model features a digital screen combined with the SpotLite Pointing System to identify targets. If you prefer a real-time visual map of the wall cavity, the LED array style is often preferred. Conversely, those who favor traditional digital readouts may find the LCD interface on Zircon models more familiar for locating stud edges and identifying live wire warnings.
Detection Versatility
Evaluate the material compatibility of the stud finder before purchase. Advanced models like the ProSensor MAX are engineered to scan through various surfaces including plaster and OSB, while the Zircon StudSensor Pro offers DeepScan functionality for deeper penetration. Identifying the specific materials in your home is vital, as some stud finders are optimized for standard drywall, while others offer specialized modes for denser building materials. Always verify if the device is intended for wood and metal detection, as some professional-grade scanners are specifically calibrated to differentiate between these two common framing materials to improve overall accuracy during installation tasks.
Storage and Protection
Investing in proper storage ensures the longevity and precision of your measuring tools. Because sensitive sensors can be impacted by debris or rough handling, storage solutions like the Casmilee Hard Stud Finder Case are available. This specific case is designed to fit a wide range of Franklin Sensors models, including the 710 and T13, and features removable dividers and mesh pockets for batteries and accessories. Using a dedicated hard-shell case prevents the tool from being damaged in a crowded toolbox or on a busy jobsite. If you frequently travel between locations, a protective case is an essential accessory for maintaining your device's calibration.
Safety Features
Safety should be a primary concern when drilling into walls. The Zircon StudSensor Pro LCD includes WireWarning technology, which is specifically designed to detect live AC electrical wiring behind the surface. This feature adds a critical layer of protection by alerting the user to potential hazards before they penetrate the wall. While some scanners focus exclusively on locating studs, those equipped with electrical detection capabilities provide added peace of mind for DIY projects. Always prioritize tools that offer clear indicators for hidden utilities, as this prevents costly repairs and ensures a safer environment while you perform mounting or renovation tasks.
Frequently asked questions
Does the Casmilee case fit the Franklin Sensors 710?
Yes, the Casmilee Hard Stud Finder Case is explicitly designed to accommodate the Franklin Sensors 710 and 710+ models. It also fits the T13, T11, X2100, X1100, and ProSensor MAX/M210 units.

This provides a secure, organized way to protect your precision sensors during transport to different jobsites.
What is the difference between the ProSensor MAX and the T9?
The primary difference lies in the sensor array capacity. The Franklin Sensors ProSensor MAX is a 13-sensor wall scanner, while the ProSensor T9 utilizes an 8-sensor array. Both models are manufactured in the USA and are designed to show the full width of wood and metal studs. The choice between them typically depends on the level of scanning resolution you require for your specific projects and the density of the materials you are scanning.
Can I use these stud finders on plaster walls?
The Franklin Sensors ProSensor MAX is specifically noted for its ability to scan through plaster, as well as OSB and other common wall materials. When using a stud finder on non-standard surfaces like plaster, it is essential to check the product specifications for compatibility. While many modern digital stud finders are versatile, always ensure the model you choose is rated for the specific wall thickness and material composition you are working with to ensure accurate detection.
Does the Zircon StudSensor Pro detect wires?
Yes, the Zircon StudSensor Pro LCD model includes WireWarning technology. This feature is designed to detect the presence of live AC electrical wiring while scanning for wood or metal studs behind walls, floors, and ceilings. By identifying these hidden hazards, the tool helps prevent accidental contact with electrical lines. Always refer to the user manual for proper scanning techniques to ensure the WireWarning feature functions as intended during your specific wall-scanning task.
Are Franklin Sensors products made in the USA?
Yes, both the Franklin Sensors ProSensor T9 and the ProSensor MAX are manufactured in the USA. These models focus on providing a clear visual representation of stud locations by displaying the full width of the stud using their respective 8-sensor and 13-sensor arrays. If you are specifically looking for American-made wall scanning tools, these two products are prominent options within the Franklin Sensors lineup that feature this domestic manufacturing designation.
Bottom line
For users prioritizing the most comprehensive scanning capability, the Franklin Sensors ProSensor MAX is the standout choice. Its 13-sensor array provides a high-resolution view of the wall, allowing for precision in identifying stud edges and centers through challenging surfaces like plaster and OSB. When paired with the Casmilee Hard Stud Finder Case, it becomes a durable, professional-grade solution for consistent use. While the Zircon StudSensor Pro LCD offers excellent value through its integrated WireWarning technology and digital display, the Franklin Sensors line is superior for those who prefer an instant, wide-area visual map of the framing behind their walls. Both brands provide reliable detection, but the ProSensor MAX offers the most robust sensor density currently available in the provided selection.
Deciding between these tools depends on your specific environment and the complexity of your tasks. If you work primarily on drywall and require an affordable, all-in-one unit that monitors for electrical hazards, the Zircon StudSensor Pro LCD is the most practical fit. Conversely, if you frequently encounter varied wall materials or require the highest level of scanning accuracy for high-stakes mounting, the Franklin Sensors multi-sensor arrays are the logical investment. Consider whether you need specialized electrical alerts or if your workflow demands the intuitive, wide-scan visual feedback provided by the ProSensor LED arrays. Matching the sensor density to your typical project requirements will ensure you achieve the best performance from your purchase.
