Cat Cams?

[rfkellner at snet.net (Rick Kellner)]

I have done some searching on Vortex, which is where I came across the
Cat Cams.  I was hoping that there were some listers on the Scirocco
list with experience.
Finally, in the case with the Autotech cams, it sounds like their
reputation is reflective of their 'advertised' specs, which are also
unimpressive.
Thanks, Rick.

I have no experience with the Autotech cams, but looking on Vortex, most
are pretty unimpressed.  You might do a search there to gather some more
info of their opinions...

Good tips, Dan.  I had forgetten all that as well...

Diversity is good!  :-)
