I agree.
Got the same question.
And then noticed…
This makes me think we’re talking about a flex implant, since glassies usually come inside a needle, not a bottle. (while some flexies ship in a vial… or “bottle”)
In which case it is possible to program/test before the install but you would need a pretty good reader to do that. phone might be a pain to pair properly.
I fear you might be mixing up two unrelated things here…
When we talk about “optimal position” we are usually talking about the position of the chip in relation to the reader’s antenna.
i.e. how to approach your implant to the reader to get the fastest and most consistent read.
This has nothing to do with the install.
Both the field detector and the diagnostics card are tools to be used on the reader, not on the implant, to help you figure out where/how to approach your implant so it gets read.
Now, about Implant position…
There’s a whole thread just about where people like their implants!
It all comes down to a combination of personal taste, implant type, implant usage and life habits.
So ultimately you are the one who should tell your installer where you want it. (and then listen to the installer’s feedback).
Hope this helps. other than that, we’re here for any more questions!
