The ProSensor MAX is our deepest-sensing model to date. With 13 larger sensors, it is designed with heavy duty projects in mind. Perfect for theater rooms, condos/townhomes, and lath and plaster common in older homes, the MAX’s Mode 2 is built to detect wood and metal studs beneath multi-layer surfaces. In addition, the MAX’s 35 LEDs allow for a very precise reading of the center and edges of deep studs. The MAX also features a low battery indicator and built-in bubble level for convenience.
