Your decision of course, But for me I’m got one in each hand in the same session, logistically easier, same setup ( implant station ) my mate who installed them “practised” on the first one and it was easier for him on the second one, It was just faster and easier all around, It also meant faster healing time ( both healing at the same time ).
I don’t know if I was just lucky, but I had the plasters off in about 2-3 hours, I had no swelling, I just kept usual hygiene practices and was fully healed 3-5 days.
I just changed my activities for the single healing time rather than a dragged out recovery.
I stopped swimming,boxing and using the gym and just ran over that period.
Suffice it to say, everybodys situation is different, in my case the Pros far outweigh the Cons and I really had no issues at all with one in each hand in the same session ( If I had more I would have done them all )
My next install I will have 2 or 3 in the same session ( Vivokey Flex one, xEM and a {hopefully} new 2in1 xSeries)
Thanks for the note @Pilgrimsmaster, I’m going to do both at the same time now. Actually, I was looking at some of the self-install information and if I didn’t already have the appointment, I would seriously consider doing it myself.
@koteeq Does your PM3E write to the HF side of your NExT without any issues?
It doesn’t even detect my NExT, I was unable to find a sweet spot, but I didn’t actually try hard, because I can write easily with my iPhone.
Hmm, that’s unfortunate. I just programmed my second NExT using the same method. First thing I did was feel around the syringe packaging, still in the plastic pouch as well to determine where the actual needle of the syringe was. Then, I repeatedly issued lf search while I moved the needle around the coil at the same time as rotating the PM3E so that it would alternate between parallel and perpendicular to the copper coil. Once I got a hit, I stopped moving, tested lf search again, and if it hit, I immediately issued lf hid clone <ID of tag to clone>. At this point, the tag seems to stop responding to lf search but does respond to lf hid read. After that, I went and tested it on two separate readers and I was granted access both times.
Once I have the NExTs installed, I’ll try and recreate this connectivity, if it works I’ll make a video.
The antenna works great, thanks 
I have a project coming up that will probably involve me making my own antenna and that test rig for the RDV4 looks really handy, are they available by any chance?
Cheers 
Not the test rig, as far as I am aware.
You can try reaching out to @TomHarkness for some direction
Unfortunately these aren’t available at this time, maybe later down the track!
I will keep an eye out just in case they ever pop up 
Is this still “A Thing”???
Thank for the update, can’t wait too see the new proxmark antenna.
We are finally in the process of getting more… should be on the store in June
With the PM3 as a bundle option?
This excites me very much.
Some people will come out of this quarantine 
My plan is to come out closer to 
Is this something I can buy somewhere? Or are there gerbers that I can ask china to make into things for me? save me an hour or 4 blowing of the CAD cobwebs
thanks @Kauko, but I meant the antenna Dev board Tom was using to prototype on
“That’s a prototype for testing
it was designed by Rfid Researchers Group and myself for my antenna R&D and produced by a factory in Shenzhen.” - @TomHarkness
I thought I’d replied to that comment
Apologies for the confusion
What platform are you wanting one for?
Tom is only on here periodically.
If it is for the PM3 Easy, @Compgeek did an awesome job of this homebrew LF antenna
Thanks @Pilgrimsmaster. the RDV4.0.
My original question was a reply to this previous comment about this post but also seems to have ended up attached to the bottom of the thread. Apologies for the confusion.
No worries, I was pretty sure you were after the RDV4 one, Like I said we only see @TomHarkness from time to time, so you might be waiting for a while for an answer.
I thought I would link the homebrew incase it was of use to you.
I got some cards in today with a notice saying the proxmark cannot change the block 0 information and I would need the accXXXX ( I can’t remember off the top of my head) reader
Is this accurate?
Finally had a use case for my Proxmark + LF Antenna. Just moved into an apartment complex that uses 125khz RFID for accessing the clubhouse/mailroom/pool/etc.
Struggled to get the Proxmark working on an older Macbook Air for half a day before trying from scratch on a Linux laptop and got everything working in less than 30 minutes! It’s an AWID tag, so I didn’t even have to clone it - I just needed to enter the facility code and card number, hit enter and voila! Magic hand!
