Features

  • Zircon's MS i520 is a multi-surface scanner with 4 modes that detect studs, metal and live AC wiring to help you easily find studs and avoid hazards
  • Both StudScan and DeepScan modes locate the edges, center and direction of wood or metal studs; Metal Scan mode finds both non-ferrous metal (such as copper pipe) and ferrous metal (such as rebar); AC Scan finds and traces live, unshielded electrical AC wires
  • WireWarning Detection indicates the presence of live, unshielded electrical AC wiring while scanning in StudScan, DeepScan, and Metal Scan modes
  • ACT (Auto Correcting Technology) automatically corrects common user errors, such as when scanning begins over a stud, while the Patented SpotLite Pointing System clearly indicates the target location
  • One fully charged 9V battery, not included, is required for the multi-surface scanner to run at optimal performance

Description

The Zircon MultiScanner i520 center finding electronic wall scanner quickly and easily locates studs, detects metal, locates live, unshielded AC wires. Complete with the latest technology in density detecting software and circuitry, as well as an ergonomic body design. Unlike other wall scanners and stud finders, the Zircon i520 stud finder has a 4-mode switch makes it easy to change functions while the ultra-bright LCD screen, SpotLite Pointing System, and audio tone all indicate the location of the target. This Zircon stud finder also comes equipped with a Signal Strength Indicator helps to distinguish between shallow and deep targets. A weak signal can also imply other non-stud objects, like wires and pipes, are present in the area being scanned. The MultiScanner i520 includes ACT (Auto Correcting Technology) that automatically corrects common user errors, such as when scanning begins over a stud, in addition to a low battery indicator to alert its users to replace its battery for optimal performance results. The tool constantly scans its surroundings and recalibrates itself if necessary. In StudScan mode, the Zircon i520 locates the center, edges, and direction of wood or metal studs up to 3/4 (19 mm) of an inch deep. Switch the i520 stud finder over to DeepScan mode and double the scanning depth to 1.5 inches (38 mm) deep and enables scanning for joists in some ceilings and floors. Metal Scan mode of the MS i520 provides the ability to locate non-ferrous metal, such as copper pipes, up to 1.5 inches (38 mm) deep and ferrous metal, such as rebar, up to 3 inches (75 mm) deep. Using Metal Scan mode, this Zircon studsensor can find studs behind lath and plaster walls, tile, drywall and stucco walls by identifying the consistent pattern of screw or nail heads in the studs. Additionally, the MultiScanner i520 is programmed with a WireWarning Detection feature that indicates the presence of live unshielded electrical wires up to 2 inches (50 mm) deep when using the stud and metal scan modes. To detect, locate, map, and trace the live wires, simply switch over to the AC Scan function which acts as a live wire detector and finds and traces live, unshielded AC wiring up to 2 inches (50 mm) deep. The Zircon MultiScanner i520 is a perfect choice for serious users, such as home improvement hobbyists and professional contractors. With the Zircon MS i520, you can safely maneuver through the most complicated of projects with the professional confidence that comes from owning a Zircon.

abunda_amazon_reviews I would like to preface this review with that I am an average joe that needs the use of a stud-finder about once every 6 months, or whenever the missus buys a new mirror or something. I've had this unit for 4 months now and have used it on two occasions. With other beeping stud finders I would find myself very much second guessing where the studs are, going back and forth, back and forth - really trying to triangulate where that 2x4 is, and with previous units I have missed a stud. I find with the Zircon MS 740 I am far more confident with my results. As expected, I still make a couple extra sweeps to make sure I get it right the first time, but the results have been much more decisive. I don't really have any cons about the unit. I like the built in marker (that ended up being much more handy that I gave it credit for) and the Stud Interface is pretty neat. I like that the unit does not turn on until it is engaged on a flat surface as well. Also I'm still running on the same 9-volt battery that I started out with. So, I'm a happy camper. Hope this review helps the next chap :);;Reviewed in the United States on October 17, 2016;;5.0 out of 5 stars;;Confident results;;Daniel;;;I would grade this new Zircon stud finder at 3.5 for reasons given below in the con section. This is the second Zircon stud finder I have. The first [older] was bought over the last 10 years and is simply labeled as STUDSENSOR. This new product is just as inconsistent as the first. The older model has a vertical set of red LEDs. As you transverse the stud, the LEDs light from bottom one at a time to the top light. The center of the stud is implied by the top light lit. As you pass the stud, the LEDs turn off in descending order from top to bottom. One's job is to judge where center is by picking a point in the middle of the upward and declining LEDs. This new model is more definitive about where it thinks the stud-center is located in scanning from left to right by beeps and when an upward pointing LED light on the wall appears, a 3 bar strength indicator is lit, and the middle of a 4 segmented bar is shown. At times it stays on until it decides to turn it off (perhaps by seeing the right edge being detected. (Scanning from right to left shows the bar, but no beep until the center is detected). As you move along you must watch the segmented, black horizontal bar carefully as it will be the 1st indication of the end of the stud (I believe the second is indicated when the strength indicator bars disappear). Pros: Center indicator of stud is usually right on. The segmented bar helps to understand the studs width if that is important to you. Cons: Inconsistent results when scanning in reverse. The user interface changes slightly. The screen is too small for the amount of information being presented; I surmise to conserve battery power. Bar segments hard to see and questionable in value. The signal strength is too weak to detect foil wrapped Zip power line. In my experience, contractors will use large hole cutters to run power cable. The cable could be resting anywhere in the space of the hole. In my application, I'm wanting the maximum depth screw into the edge of a 3/4. The sensor's limitation (as is also with other sensors on the market) is detection up to 1.5". I have 5/8 drywall. That leaves a screw anchor of only 1 inch. This unit will not see most of the power lines. Nor will it see any low voltage cable used for intranets, appliances, etc. [In some counties, the code requires the contractor to nail across the stud a steel plate to avoid drilling into wiring.] Battery cover is a bit difficult to lock in - wires attached to battery post are in the way. Battery life is not specified. The higher up the wall you use this product, it's more important to have a straight on view of the screen, and the use of a 3rd arm for balance and the use of a marking instrument. I did not validate the detection of non-ferrous metal.;;Reviewed in the United States on November 5, 2017;;4.0 out of 5 stars;;Pricey, good center stud indication, but inconsistent in readout ±0.25 to ±0.5";;Wishful Dreams - Tim Townsend;;;I didn't see many reviews for the A250 model specifically so though i would give a few thoughts. If you look on Zircon's site there is a dizzying array of models that all seem to have the same spec's. I went with this model over the A250C because it had the same sensing depth for about $10 cheaper than it's color version. I bought this because I need to run some cabling in a new house which could potentially involve drilling in unknown walls, and I wanted something to survey the wall for AC and metal pipes. For the price I suppose I'm a little disappointed. On several occasions I swept over a wall and it wouldn't detect a stud or two in certain places. Construction is simply 1/2" or 3/8" gypsum, with insulation so this isn't a complicated wall. It only picked up on the stud when I moved over the obvious nail head. And yes this if a fresh battery. In the metal sensing mode it accurately picked up on nail heads. AC mode seemed to work well, on a very narroy wall it detected that there was AC around the corner about 6" away. Moving around the corner beside the switch it turned off, credance to it detecting "back" and not "side to side". On one occasions the AC light came on and stayed on for about 6' worth of sweeping, which seems like it may have been a fluke. The one big problem I have is the button on the side has terrible tactile feedback - there's a click when it's on but there is very little throw to the switch. All this translates to is finding yourself holding the button very firmly so it doesn't accidentally turn off, making it awkward when reaching to find a stud. I wish manufactures would change this to push-release to turn on and push-release to turn off.

The higher up the wall you use this product, it's more important to have a straight on view of the screen, and the use of a 3rd arm for balance and the use of a marking instrument. I did not validate the detection of non-ferrous metal.

For the price I suppose I'm a little disappointed. On several occasions I swept over a wall ...
I didn't see many reviews for the A250 model specifically so though i would give a few thoughts. If you look on Zircon's site there is a dizzying array of models that all seem to have the same spec's. I went with this model over the A250C because it had the same sensing depth for about $10 cheaper than it's color version. I bought this because I need to run some cabling in a new house which could potentially involve drilling in unknown walls, and I wanted something to survey the wall for AC and metal pipes. For the price I suppose I'm a little disappointed. On several occasions I swept over a wall and it wouldn't detect a stud or two in certain places. Construction is simply 1/2" or 3/8" gypsum, with insulation so this isn't a complicated wall. It only picked up on the stud when I moved over the obvious nail head. And yes this if a fresh battery. In the metal sensing mode it accurately picked up on nail heads. AC mode seemed to work well, on a very narroy wall it detected that there was AC around the corner about 6" away. Moving around the corner beside the switch it turned off, credance to it detecting "back" and not "side to side". On one occasions the AC light came on and stayed on for about 6' worth of sweeping, which seems like it may have been a fluke. The one big problem I have is the button on the side has terrible tactile feedback - there's a click when it's on but there is very little throw to the switch. All this translates to is finding yourself holding the button very firmly so it doesn't accidentally turn off, making it awkward when reaching to find a stud. I wish manufactures would change this to push-release to turn on and push-release to turn off. Will update as I use this more but I was hoping it would be leaps and bounds over the simple Stanley (with AC detection) that i've had for probably 15years.

Best stud finder for home and DIYer
Money well spent. Bought this because I just recently bought my first home and I have lots of projects, small and big, in mind. With that said, I knew I would need a good stud finder. This thing is amazing! The technology built into, the accuracy of it....all just wow. Even has a built pencil for marking the center and comes with 3 extra pencil refills tucked behind the battery. I do encourage anyone buying this read the manual!!! If you don't then you will miss out on small features that would of made the task simpler or you simply won't know what the beeps and symbols mean.
