xG3 Biomagnet -- suggested locations

I was a bit hasty to get my xG3 done, so I just went with the most common location for NFC/RFID chips. It’s on my left hand, but now I’m planning on implanting the xEM chip very soon. I noticed that most proximity card readers on buildings or exterior door locks are generally on the right side of the door and that scanning my chip and opening the door would be generally easier to do with the same hand that has it implanted.

If I were to put an xEM in the same left hand, how far apart should I space it from the magnet to avoid interference or other complications? Is there another spot on the same hand that wouldn’t be difficult to have a professional piercer install it on that would be similarly safe enough to more easily avoid crushing and far enough away from nerves, tendons, or bones or other questionable locations? Regardless of the information I receive on here I will still consult with a medical professional before making any (more) hasty decisions.

Here’s a picture of my xG3 in its current location.

Has anyone had any complications with their xG3?

I would say at least 5mm minimum.

Mine seems to be working great, despite its location. It is a very mild tingle when near alternating current power sources, but admittedly it’s somewhat weak.

Oddly enough I feel it just the same and sometimes better with the palm of my hand towards the power source despite the injection site being on the back of my hand. I can somewhat feel it with the back of my hand against the insulated wires, but with less definition in the sensation.

Swelling went down in a couple days and I consciously took care not to do very much with my hand for about a week.

X-Rays! Now that I see it, the xEM (on the right) looks a little close to the bone… but it hasn’t caused me any issues yet. So far this placement is working out great.

Thanks for the images! Yes both look rather close to bone, but if they are not causing you issues, then it should be ok. There is simply an increased risk of breaking if they happen to be trapped between a blunt force trauma and that bone.

So the bevel of the needle is the part that comes to a point correct?

The big difference came when inserting into real human skin, particularly skin that was thoroughly cleaned and prepped prior to injection (so, all installs). In fact, the skin prep used and style of prep made a big difference to needle insertion force. To help illustrate why this might be, let’s look at a typical needle bevel;

Parts 2 and 3 are the actual cutting edges that perform the incision. Part 1 is typically not a cutting edge, and simply pushes it’s way into the incision in the skin. This is where the problem typically occurs. In all reported cases, it is “getting over this hump” which is difficult and requires much more force. The cutting edges (2 and 3) had no trouble at all getting under the skin, therefore the needle’s “sharpness” is not the issue.

I really want to see how the tragus implant was done. That’s a lot of material to shove there! Clearly it worked, but man, tight quarters for that giant needle


To make things a bit clearer about the bevel.

The bevel is the side of the round tube that has been cut, not just the pointed bit. In the image @Pilgrimsmaster re-posted, the problem is that parts 2 and 3 separate the skin as it cuts, which leads some skin to literally go down the length of the inside of the needle… like you’re scooping up skin into the needle. Then along comes part 1, the rear edge of the bevel, and it grabs that skin bit you’ve been scooping up and everything gets hung up there. The skin that has accumulated inside the needle now has to do a 180 and completely fold back the other way, and be dragged into the incision.

To stop this from happening, this is a video of a piercing needle based installation of a chip. It is an alternative method that can be used by piercers if the injector is compromised, not included (prototypes), or the piercer feels more comfortable using their own equipment and methods. The point is that you can see the professional flip the needle over so the bevel is down when performing the incision.

The needle is “bevel up” as the artist is deciding where to perform the incision.

The needle flipped over, “bevel down” as the artist performs the incision.

Here is the full video, with the flip occurring at around 10 seconds in.


Unfortunately I don’t have a video to share. Next time (tragus left ear when the xG3 is back in stock) I’ll definitely film it and share the video afterwards.



Installed the Spark in my arm and xG3 between 4th and 5th metacarpal.

xG3 installation done and done!



It’s been over a week and my xG3 is still wandering around the back of my hand quite a bit. I don’t have a lot of fascia thickness on the back of my hand so I’m not sure if it will ever settle. But to help it out, I took a small paperclip and modified it to surround the magnet.

I put some tape very lightly over it and it hasn’t moved all day.

I only did this once. It was dumb to do, especially before it has settled down, but I couldn’t resist. And I had just moved it back into position anyway.


Upon further thinking, using something metal long term around a healing magnet might not be such a good idea. I have replaced it with a small piece of craft foam.

Mostly healed now, decent strength and walking by the server room at work feels a strong tingling sensation.


Mine is still moving around a bit (back of hand) but generally stays in the same area.
I don’t feel anything around my microwave. I haven’t felt anything as far as “sense” goes…other than other magnets.

you should got through the security gates at the library from a friend. They are very strong. I don’t know where to implant the magnet from DT (I have an other one - I feel the fields from 1 meter away)
Ear: no way, we have comunication devices at work.
