ZIRCON SuperScan M4 Stud Finder

Featuring new, revolutionary Target Control Level 1 Technology, the Zircon SuperScan M4 advanced wall scanner is tuned to find clean, wood studs while filtering out metallic false positive objects, such as plumbing, conduit, straps, brackets or ducts, hiding beneath surfaces. The LoLevel and MetalliWarning Indicators alert to the presence of dangerous, deep, less dense false positives and metal targets, reducing the chance of accidentally drilling into a piece of metal or plastic pipe. with the addition of AC Scan mode, users can search for hot, unshielded AC voltage. The SuperScan M4 offers 5 distinct detection modes - TC, StudScan, DeepScan, Metal Scan and AC Scan. A 4-mode switch makes it easy to toggle between functions, while the ColorTrip Display conveniently details information. The screen illuminates pale blue in TC mode and locates the center, edges and direction of wood studs, while enabling the user to identify safe-to-drill zones by utilizing the new 'Trust but Verify' technique. When TC mode is off, the tool will perform in StudScan mode indicating both wood and metal studs. DeepScan mode doubles the scanning depth to find wood and metal studs beneath extra layers of drywall or paneling. The dedicated Metal Scan mode helps users identify both ferrous and non-ferrous metals. AC Scan mode enables users to locate and map the wall for live, unshielded AC electricity.
New target control mode locates the center, edges and direction of wood studs and not metal, up to 3/4 in. D (19 mm) behind surfaces, identifies safe-to-drill zones between adjacent drywall screws, nails and protector plates
StudScan mode locates center, edges and direction of wood and metal studs up to 3/4 in. D (19 mm)
Deep scan mode doubles the scan depth of wood and metal studs up to 1-1/2 in. D (38 mm)
Metal scan mode locates ferrous metal up to 3 in. D (75 mm) and non-ferrous metal up to 1-1/2 in. D (38 mm)
AC scan mode locates live, unshielded AC electrical wiring up to 2 in. D (50 mm)
WireWarning detection alerts to live, unshielded AC wires up to 2 in. D (50 mm)
LoLevel indicator displays low (weak) signal objects, such as plastic water pipes, while in TC mode
Signal strength indicator helps distinguish between shallow and deep targets while in studs can and DeepScan modes
MetalliWarning indicator turns on when metal is detected in TC, studs can and DeepScan modes
ACT (Auto Correcting Technology) automatically corrects common errors, such as when scanning begins over a stud
Low battery indicator for optimum performance (9-Volt battery required, not included)
Target spotlight illuminates on screen when target is detected
Colortrip display illuminates pale blue in TC mode, green in deepscan mode, blue in metal scan mode and red in AC scan mode and to alert the presence of live AC electricity
Spotlite pointer shines an arrow-shaped light on the scanned surface to indicate target location
V marker groove enables accurate marking of target location

I need to find an electrical outlet covered by wall board during construction. Advice. Just purchased a M4. Appreciate any tips.

is this detecting the drywall screws? i need one to detect joists to nail plywood to that don't have any metal. some joists are bowed a bit in the center.

What is the difference between K4, H4, M4? The website doesn't make that really clear. Only thing so far is the color of the unit is different. Thanks for the video too

Mine won't calibrate. Talking with Zircon this afternoon.

I dont think it’s the stud finder. I think y’all are not using equipment properly. I just bought it and mine works fine.

Informative, but I wish you had spoken. Thanks.👍

Yup, the more reason I don't buy Zircon anymore... they're still unreliable information. Thanks for reviewing.
