## Features

- The top model has been launched in Japan with a U.S. patented (8 pieces) Franklin underground sensor. Equipped with 13 sensors and 21 high-definition LEDs, this underground sensor allows you to quickly and easily find the position and width of the student that cannot be seen behind the wall. Find the "center" of the column behind the wall at a glance. Useful as a base checker for studying nails, etc. In addition to the functionality of previous company's products, it is also equipped with an active wire meter to detect that there are wires currently being current
- Wide measuring surface with a width of 7.1 inches (18 cm). The 21 LEDs on the side makes it easy to see where the pillars are. LED lights up to indicate where the pillar exists
- Advanced multi-sensing technology utilizes 13 sensors to detect "multiple" studs at the same time. It also allows for accurate detection using the principle of triangular measurement. In addition, it can detect objects in deeper positions. (Can detect up to 1.7 inches (43 mm) deep.)
- Easy to operate. Just press the button. Press the button and place it on the wall, the LED will light up and tell you the position of the post. It also runs on 2 AA batteries, making it very convenient
- Size (W x H x D): 7.4 x 3.3 x 2.4 inches (18.7 x 8.5 x 6.0 cm); Weight: 9.1 oz (273 g); Power supply: 2 x AA batteries; Detection depth: Approx. 1.7 inches (43 mm); Bubble level; Active wire meter; Japanese instruction manual (English language not guaranteed). This sensor detects changes in capacitance and detects objects behind the wall, so there may be cases where stable detection on walls (such as plaster, etc.) with unstable density. Cardboard is composed of alternating layers of air and paper that may cause noisy false detection due to capacitance changes locally when sensor is moved. Commonly used wall materials such as drywall boards and wood boards have a consistent density for stable detection

## Questions & Answers

**Q: What the major differences between M20 and T13 and Pro 710+?  just wanted to decide which one to buy**
A: The ProSensor M210 has 21 indicator lights vs only 13 on the other models (important note: this is number of lights only, not number of sensors).  This allows a more precise indication of the stud limits.  It also has 2 AC voltage indicators at each end in case live wires exist beneath the wall or ceiling surface you are scanning.  These "upgrades" were worth the additional $5 to me.

**Q: Will it work on a sprayed on rough ceiling?**
A: Thank you for your question. Unfortunately our sensors do not do well with rough surfaces. Our stud finders function by sensing any change in density, and when the surface is very rough and bumpy it creates air gaps between the unit and the surface which leads to false readings.

**Q: Puedo encontrar los stud de metal?**
A: Yes, this can find metal studs. It works by finding any change in density behind the drywall, so it will find both wood and metal studs simultaneously.

**Q: Does any model of the Franklin Sensors work better with sheetrock over old wood lath walls than the others??**
A: Our best and most accurate sensor is the M210. This stud finder has a maximum detection depth of 1.7". Depending upon the total thickness of the sheetrock over old wood and lath, this finder may be your best bet. We cannot guarantee that it will work however without knowing the thickness and the makeup of the materials. Good luck!
