xG3 v1 VS v2 finger sensing

i am sure someone in the bible belt would frown upon one playing with his magnets… :slight_smile: :rofl:

I kind of want the interaction when I choose it. I have an xG3 v1 in the pad of my middle finger and I’m going to put an xG3 v2 in the pad of my thumb on that same hand. That way they’re far enough apart that there shouldn’t be too much accidental interaction but I can play with them when I want.

My question is, how are y’all getting these into your fingers? From the pictures I’ve seen they seem to be pretty big. And I feel like it would be difficult to inject them with the needle. Do you use a scalpel or is there actually a way to inject it normally? I feel like it would be really cool to get one or two of these for my fingers to go along with (but not next to) the Titan.

Some people with larger fingers (or I assume they’re larger) have injected them, I personally don’t think my installer would be comfortable injecting it and I also don’t necessarily want to sever all the nerves in my finger so I’m gonna have my plastic surgeon do a scalpel install

Related to this, how does the Titan compare for sensing? There are a lot of posts about Titan lifting but not much for sensing. (Please direct me if I’ve missed a thread)

Recognizing that it’s all subjective, does anyone have the v1 and the Titan for comparison?

Well, Not a thread as such, but here’s a clue :stuck_out_tongue_winking_eye:

In fairness it is quite difficult to show sensing with a video or photos compared to lifting. There is a smattering of descriptions throughout the forum

Lol, @Pilgrimsmaster! I read all those threads already! I didn’t see many real-world reports of how strong the sensing is, esp in comparison to XG3. Maybe I should read them all again :smiley:

I can just tell from my experience:

I have a titan and a xg3 v1 in my finger and a xg3 v2 in my knife edge.

I get the best sensing from the knife edge xg3, second place goes to the finger xg3 and the titan takes the last place

However finger xg3s are not practical and doable for most people, its dangerous and just fucking huge.

My recommendation for a sensing magnet is the titan!

Mine titan is now about 2 months installed and nerves are probably still regrowing and I’m expecting more sensing in the future.


Thanks mrln! Very helpful. I’m nervous about the Titan fingertip install and was planning on a V1 fingertip install. I think it should fit, based on a toothpick mock-up. I will do a Tital mock-up tomorrow. I’ll keep your experience in mind. Much appreciated.

Edit: I’ll also do an edge mock-up day to test that experience.


I’ll make a video about it in a few to set some goalposts, and we can get some people’s feedback from there.


The Xg3 Finger Installation will be way more invasive and the scar and tissue damage will be most likely way bigger.

The big xg3 needle will damage more tissue than a professional titan install. I don’t recommend anyone installing a xg3 in a finger…

The risk of problems seems like it is not worth it… I would never again install a xg3 in one of my fingers…

Thanks, @mrln I appreciate you sharing your experiences. Edge also seems to have plenty of nerve endings… it’s just not as cool as a fingertip! Of course, losing sensation in a fingertip due to a bad install is least cool of all.

The toothpick mockup on the edge is totally fine. I’ll try the Titan mockup tomorrow.

I’ll be searching for a professional installer here in the Twin Cities and trying to find one to do a scalpel insert into a fingertip seems even more challenging than finding a pro would would do a needle insert into any location. So many factors to weigh!

@Satur9 - THANK YOU SO MUCH for that great example. Despite your caveats, the laptop transformer is a great everyday test for measurement, and your 8mm measurement was informative. it was also great to see the two implants lying together with your hands for context. The Titan is a lot smaller than I expected, and the XG3 is longer than I expected, even with my mockups lying around. I could also see - barely - how it looked in your finger.

Thank you for your time. I really appreciate your video.


So I’ve been holding back from sharing this too much because I have sent a device to @amal and have been waiting for his input but since we’re on subject…

I’ve spent about a year solo and six months in a CNRS IT lab studying the stimulation of magnetic implants (sensitivity, haptic rendering etc…).

But long story short I came out of this with a couple ideas on dedicated devices to test (in a standardized and repeatable manner) magnetic implants and also make use of them for sensory substitution training and AR feedback. The hole project is called SMIS and I have teased it a bit on the discord. I have already made and distributed a couple of SMIS cubes and I’m making good progress on the app that goes with it but I’m still correcting some things and figuring out how to make them available.

The idea is first of all to make a convenient way for anyone to play and experiment with their magnet even without having diy skills. But as a side effect it also means we will be able to collect results from standardized tests with identical devices and compare them / do stats.


Let me know if you want help designing for manufacturability. That’s what I do.

That’s exactly where I need help actually. I can deal with the app and I’ve made some prototypes at home but I’m a bit at a loss as to how to proceed next :thinking: I’ll pm you to avoid derailing this post, thanks!


I’m assuming xG3 v1 for the knife edge? I’m considering putting one there but am undecided on which version.

No problem mate

This thread might be worth a look see

You mentioned V1 here

But here

Which one are you leaning towards? do you know the difference between the V1 and V2?

The V2 is Newer, but not “better”, just different.

Short version

V1 Sense
V2 Lift

Check out the forum post where we compare the lifting strength of v1 vs v2 – Lifting power of the xG3: v1 vs v2

This has some great examples

I assume you have read up on the product description
