I think Martin gave an excellent review of the Rig Expert analyzer.  I have
the AA-35 model that covers bands up through 10M and I can confirm just
about everything Martin said about his model , which covers up through
higher frequencies than my model..

I have had an AA-230 Zoom for a couple of years, pretty much since it 
was first available and I rate it as excellent.

The screen is not huge but it is reasonably bright. If I choose the 
right colour set it is even readable here in the Thailand sun.
The keypad operation lacks a little intuitiveness initially but once you 
get the hang of it it is quick and easy to drive.
I prefer the earlier version of the desktop software which is available 
and integrates nicely.
I curse the use of AAA batteries and would have preferred the larger AA 
size. In its defence it runs on USB when plugged in.

I have used the TDR function and it seems to work well enough. On my 40m 
dipole it shows the discontinuity at 56.78m which is close to what I 
know it really is. It is certainly in my experience good enough to 
identify within about 6 inches or so a bad connection or damaged cable.

I recently cut a lot of stubs and used the technique in the AA-230 Zoom 
user guide to determine cable lengths using R and X, this also works 
very well. Compared with my VNWA3E and SimSmith it was very well correlated.

I haven't found much use for its Smith chart function.

It creates Touchstone s1p files for use with various other analysis 
tools such as AC6LA's superb Z plots, AE6TY's superb SimSmith and others 
of course.

The SWR meter function is quite useful.

It is light and easily carried though do protect it. Mine came with a 
cheap pvc type case that has kept it well so far.

I think it is a super field tool. I have a DG8SAQ VNWA3E which is 
excellent on the bench and for a lot more different things but the 
AA-230 Zoom I find to be an equally good single port antenna analyser.

All round I give it 5 stars but just a slight moan about the batteries 
being a bit short lived.

Mine is not the BlueTooth model but I can see where that might be useful 
if you need the galvanic isolation. You can achieve the same by using it 
standalone, storing a sweep and importing to a pc in slow time. Even if 
you store one sweep you have all the available data to display other
