Kingdder 200 Pcs 3D Magnetic Tracking Dot for Scanner Scanning Reference Point Marker Diffuse Reflection Positioning Targets for 3D Scanning (Inner 6.0 mm Outer 10 mm)

Didnt count then but they all look to be there.They work great and have just enough hold to stick and stay put .but come off easy when removing them

i wish the magnetic was a tad bit stronger they can fall off pretty easily but it does the job fine and they're easy to remove which is a awesome feature. they may not work for everything but when you have a metal surface youll be glad you have them.

I really like these. My only issue is that I didn't buy more on my first go around.Of course, they only stick to ferrous materials. But the simple application and easy, clean removal are really nice. And of course, the ability to reuse them is also a nice plus.One benefit I did not expect, is the better tracking on flat surfaces because of their thickness. My scanner likes seeing stuff stick sometimes. Where I would lose tracking while trying to scan a large fuel tank with decal dots, these allowed my scanner to see some 'terrain'.Recommend.

These magnetic markers are an absolute lifesaver! They’re designed just right—light enough that they don’t risk scratching or damaging surfaces, but strong enough to stay exactly where you put them. The fact that they’re reusable is a huge bonus, saving me money compared to disposable markers. Even better, they’ve cut my workflow time down drastically—I’d say placing and removing markers now takes only about 1/10 of the time it used to. They make scanning smoother, faster, and a lot less frustrating. I honestly don’t know how I managed without them before!

Magnetic surface very weak.

I got a chance to try these and thy work pretty well for scanning. But after I purchased I was trying to browse amazon and a live stream started to auto play and I got the pleasure to hear about some random jobless persons toe fungus. Fun

I was having a tough time keeping my scanner tracking on my car, I stuck these all over the fender and hood and started getting much better tracking. If you have large items that are smooth and don't have a lot of features to track these can really help.

These markers work well on magnetic surface and I have also used them to easily just lay flat on a surface for global marker scans. The overall quality is good even if the magnetic power is a little light but that is to be expected with how thin they are and I would not want them to be any thicker for best usage. I love having easily reusable markers which make it much easier to place them instead of peeling off adhesive labels and just disposing of them when done. They save both time and money.
