## Description

From the Manufacturer The Zircon MetalliScanner m40 Handheld Electronic Metal Detector quickly and easily detects metal in wood, drywall, paneling, tile, stucco, plaster, concrete, and other non-metallic surfaces. It locates ferrous (magnetic) metal up to 4-inches (102 mm) deep and non-ferrous (non-magnetic) metal up to 2-inches (51 mm) deep. MetalliScanner m40 solves the very difficult problem of finding studs in lath and plaster walls. It works by finding the pattern of nails that attach the wood lath to the studs. MetalliScanner m40 finds plumbing, ductwork, rebar, nails, and screws in your walls, floors, and ceilings, and is great for scanning reclaimed lumber for hidden metal. FEATURES: MetalliScanner m40 has two scanning positions, each with a progressive LED display. As it approaches a metal object, the red LEDs progressively light from the bottom up. The top lighted blue coil and an audio tone indicate when a metal target is located.

Review: Great sensitivity, quality product - I love it! - Brand/make: I'm very glad I spent the extra $10 to get this one instead of the Little Wizard II. Zircon seems to be the industry leader in this sort of technology, and seems to be a brand I can trust and get good support from. Their website is well maintained. It's designed in USA; assembled in Mexico. I think it's a newer design than the Little Wizard II, since it was first released in April 2007, whereas the Little Wizard II product manual is dated November 2002. Purpose: I bought this primarily for finding staples/screws/nails in old wood I want to reuse, but I'm sure I'll find other uses for it too, like finding things I drop, finding studs and nail lines, etc. Size: It's a little bigger than I imagined it, but that's a good thing - my fears of it being delicate or likely to be broken were completely unfounded. Battery: I only just got this, so I can't comment on battery life, but it's nice that it came with the 9-volt battery already installed and ready to use. Broad/pinpoint usage: You can use this lying flat for doing a broad sweep, then turn it up and point it like a gun to pinpoint the exact area. That's really handy. Proper usage: This is a sensitive, quality device. Like the directions say, if you move it around quickly changing its orientation, it will give you a false positive briefly, but used properly, it'll work great - just use a steady hand and don't twist it around quickly. Lights/indicators: The scanner has a green "READY" LED under a four red LED "bargraph". This is duplicated on the other side, so you can conveniently see it regardless of orientation. Furthermore, when you're closer than 4 lights, the blue senor lights up and buzzer sounds (engineered at just the right volume, IMO, to be audible but not annoying). Calibration: Rather than fool with a little adjustment screw till you get it to stop whining (like I saw in a video for the Little Wizard II), this is auto-calibrating. Just hold it out away from any metal while you turn it on, and it calibrates based on its surroundings. This is also helpful when narrowing down a piece of metal in an area with other smaller pieces. Just let off of the trigger and turn it back on where it is, and it'll be better calibrated to pinpoint the large piece (strongest influence). Metals: This detects ferrous and non-ferrous metals, though it is more sensitive to ferrous metals. I'm not sure how it works, but there may be a different mechanism involved. For example, with ferrous materials, the scanner seems most senstitive when the object is inline with the sensor rather than turned perpendicularly, whereas overall proximity seems to be the most important factor in detecting non-ferrous metals, regardless of orientation. Large object detection (pinpoint orientation, high calibration): Item: [distance at first light], [distance at buzzer] 5-qt stainless mixing bowl: 5.5", 3.5" heavy lineman's pliers: 5.5", 3" 3/8" OD copper tubing: ~2", ~3/4" (similar for 5/8" OD copper pipe) 14-AWG 2-conductor Romex: ~1", ~3/8" 0.024" thick aluminum plate: 4.5", 1.5" (Your mileage may vary...) Small object detection: This found one leg of a common office staple (~6mm long - pretty small!!) in a piece of wood. Properly oriented, it's enough to sound the buzzer. Oriented non-optimally, it may only light up 2-3 lights, but I'm still convinced it would find it buried even an 1/8" in both broad or pinpoint orientation, if you're doing a properly careful search. For non-ferrous metal, I got similar results with a 14mm piece of solid telephone wire. Sensor geometry: The sensor is not as symmetric as it appears. I used the two tiny bits of metal mentioned above to "map" it. The intended pinpoint end is sensitive, whereas the other end isn't very. In the middle zone, there's a variation of sensitivity depending on the material. For ferrous metals, it seemed more sensitive in the very middle, whereas non-ferrous materials were better detected in either direction away from the very middle. Magnetized materials: The usage sheet states: "Magnetized materials may cause false, unstable indications." After experimenting with a small disk-shaped fridge magnet, I don't think that will make a big difference. It seemed to detect it somewhat better facing into one of the poles, and a little less coming at it from the side, which is about what I expected. Bottom line: I'm very pleased with my new "toy" and expect it will serve me well for years to come.
Review: Why it works for some and not others - I have been using this for several months and I am able to use it so that it is 100% correct all the time. How you use it and what you are trying to detect makes a difference. I use it to quickly scan the surface of wood for ferrous metals before I put it into a thickness planer. If a thin nail has been driven into a board and I am trying to detect it from the other side (detecting the pointed end of the nail), the Wizard needs to be within 1/2" of the end of the nail. If I am trying to detect a large mass of metal (like an I-beam :) it will detect it from 5+ inches away. It gives many, many false positives (that is, indicates there is metal there when there isn't). The Wizard is constantly adjusting itself to accomodate the substrate the metal might be embedded in, which is always changing since you are moving the Wizard around. However how the device shows false positives is different than how it shows genuine positives (that is, metal that really is there). When I see false positives I move it back and forth over an area that doesn't have metal to let the device "set itself to 0" (i.e., the lights go out). Then slowly going back over the area in question will reveal the truth. I am very happy with this device. I'm only giving it 4 stars because of the useless, too generalized, information given from the manufacturer about the parameters for which it will detect metal.

### ⭐⭐⭐⭐⭐ Ziron m40 for ceiling crown molding nailing
*by D***S on February 17, 2013*

I am putting in crown molding throughout our house. I use a regular Zircon stud finder to locate wall studs for the crown molding finish nailing into the walls. However, the ceiling is constructed of ceiling joists with 3 inch strapping applied 16" on center across the joists (also 16 in. on center), then blueboard, and skim plaster. A regular Zircon stud finder, even the deep penetrating ones, do not find the joists because of the air gap between the blueboard and the joist since the blueboard is nailed to strapping) and are often confused with the strapping (because it is 3 in wide and not what the Zircon expects as a typical joist width) and stud pattern. I recently bought the Zircon m40 to find the nail pattern in the ceiling to establish the strapping location (and direction) and the joists. This unit does a fantastic job of finding all the nails and in the pinpoint mode, will locate them exactly. It only takes a bit of work to mark the location of nails and develop a pattern that quickly identifies location and direction of the strapping and the joists. This makes nailing the ceiling edge of the crown molding secure into either strapping or a joist to hold the molding firmly against the ceiling. The other method is time-consuming and requires drilling pilot holes in the ceiling or opening a light fixture to locate the joist or strapping and then determining the center spacing of both and attempting to map this out to the walls. It doesn't take much to be off a lot around the walls and miss joists or straps with ceiling nails and have loose crown molding. The Zircon MetalliScanner solved this messy problem for me quickly, easily, and with no mess and drilling, and inaccuracies.
