Hi folks does anyone know what the difference is
between The MicroHunt (I have one and like it) and
the Pocket fox (http://www.byonics.com/pocketfox/)?
It looks like the pocket fox is more versital but the
MicroHunt is smaller and simpler (a good thing for
loanable gear).
I am considering buying a set to get some ARDF type
hunts going in Seattle.
Thanks for your thoughts.
