I've only seen photographs, but the new unit, the NanoVNA-F appears to be fully enclosed, not the club-sandwich stacked construction of the original Nano.  For a case to protect it, something like a  large change purse would probably suffice if you could find one that wasn't too girly-looking.  Given that you'll probably want to carry a couple short RF cables, a USB charging cable,  and adapters to different coax formats, the imitation Pelican cases sold by Harbor Freight are very solid and protective with their pick and pull foam insert.  They have a little one that often goes on sale for about $10 that's very cool.  I have a couple of their medium sized cases for other test equipment that bounce along nicely on job sites.

Frank never responded. Case looks nice but won't fit - guess I have a new paperweight?
Hope he is OK?

The case I got from Frank fit well after I rounded the corners around the USB port.

Frank refunded my money. As he points out, there appears to be a lot of mechanical variations.

If you have an hour, here's a pretty good YouTube video tutorial on the use of the NanoVNA.  The fellow starts off with a technical explanation then quickly moves to the test bench for some good  examples demonstrating the use of the Nano in practical radio situations.  Later on he even gets out a Millen grid dip meter and ties things all together.
By the way, don't worry if you don't have one of his cute little torque wrenches for coaxial connectors.  In a metrology lab those get used a bit.  In the field or on the test bench, I haven't used one in twenty years, just calibrated fingers.

I just received my Nano-VNA-F.  It took six weeks to arrive from AliExpress, but was well worth the wait!  Somewhat larger display, but instead of just a couple PC boards, it is very professionally packaged in an extruded aluminum enclosure, with ENGRAVED legends that are filled with white lettering and graphics, a very nice package indeed.  The enclosure provides shielding, which will likely improve the S/N when on the edge of performance with the original Nano-VNA offering.  

Thanks so much for the information, Norm!

It appears that the anticipated 3 ghz NanoVNA2.0 now exists in hardware and it's not just vaporware.  The linked article brings out the fact that there are two tracks, both calling themselves 2.0.  The Owocomm version is the one to watch, and the article indicates that Owocomm is basically just developing it and will set it out for others to manufacture without any license or hindrance.  The planned version is still the itty bitty screen but I have to believe that some smart cookie will build one around at a least a 4 inch screen.  Those of us with old eyes can still use it with NanoSaver and our laptops.
Folks who do 1296 and 2304 mhz will find this a nifty step, and more dynamic range is promised as well and for not a lot of money.  I'm happy with my original version for messing around the house, but I might have to pick up one of the new ones for my keychain.
Keep your eyes open for more coolness to come.

Norm,

You said "If we can only get a similar grade of shirt pocket spectrum analyzer for fifty bucks we'll all be grinning."

Take a look at SDRPlay1A with the SA software. In your shirt pocket for a bit over $100 bucks. Still needs a PC though.
