So am able to get a search, but when I have to change commands, I have to type and then i mess up.

Up Arrow moves through your history of previously typed commands.

Yeah, any movement of your hand loses progress, I always keep the hand I’m programming and the Proxmark as still as possible, and type slowly one handed. You’re almost there!
And this! Makes retrying commands easy!

To elaborate I would type the clone command without my tag there. Do the detect step to get the correct position. Then I just need to click up a few times to get the clone command any hit enter. 1 finger usage at its finest?

ok, so i got it to a position where it said everytime
pm3 --> lf search
NOTE: some demods output possible binary
if it finds something that looks like a tag
False Positives ARE possible
Checking for known tags:
No known 125/134 KHz tags Found!

Try lf t55xx commands
but then i get this
pm3 --> lf t55xx detect

Usually this means you’re incredibly close just not quite there, but it’s also possible that the blue cloner wrote a bad config that it’s failing to detect.
Get to the same point then do
lf t55xx wipe
And then go from the search again

Just for reference this issue is why you will find many people strongly recomending the RDV4 with the LF antenna DT sells. Despite how costly it is. But it’s understandable why people choose/have to go with the easy 
I have even read my cat’s tag with it which I have no clue where it is… While she was fidgeting

is there anyone in Indianapolis that we know that has one?

Don’t be discouraged though! It’s much easier to get the right position with the ProxLF antenna (slap it roughly over your implant and call it a day!) but it IS possible with the PM3 Easy
I couldn’t justify the expense of the RDV4 and ProxLF for the few implant writes I do, and at times finding the spot is frustrating. It was hours before I could do it consistently but now I have a feel for it it’s pretty fast. Don’t give up, you’ve got this!

They usually have stock, but not as cheap as DT.

Has anyone tried using the better antenna on anything other than the RDV4?

Only compatiable with the RDV4 i’m afraid
FYI
Red Team Alliance generally hold RDV4’s
Not sure about the LF Antenna

Yes the creator of the LF antenna for the RDV4 @TomHarkness and @amal I think, heres some info:
And I checked hacker warehouse has the LF antenna and the RDV4 in stock ATM apparently, if red team alliance has them there good too.
EDIT:
I noticed after the fact you said
I read it as:
tried using a better antenna.
You can’t use the RDV4 antenna with the easy, easily as the antenna has some of the circuitry on it in the RDV4 so that it’s modular where as the easy is all together.

So is that a yes or no, I see two answers.
Might try taking scissors to cut the skin around it. hopefully i wont hit a vain. wish me luck.

No to a plug and play solution, kind of yes if you want to buy more gear and wind your own antenna or modify one. It’s not easy.
That said, your antenna will be able to do it, I own a PM3 easy with stock antenna. From your ‘hw tune’ results your antenna is fine just fiddly.
Bad idea! Not recommended! Can get you closer, might help with programming maybe, but you shouldn’t need to do this and it carries a high infection risk

I am still unable to get this to work with the ProxLF antenna and the Proxmark3 RDV4.
I get:

Then when running ‘lf t55xx detect’ I get:

Well it found it so you should be able to write to it.
Do you have a card to clone to it?
So I have another NExT chip that i tested so i know what it is supposed to look like when doing it.
I get this.

Seems like that is what I should get when I try on the one I am having trouble with.
