geee, and it only costs as much as a ClearNav... except without the
IGC certified built in- wait it doesn't even it's own GPS engine for
that matter (although for the price of another ClearNav a talking one
can be purchased to go with it.. but would still leave you needing the
logger...

Not wanting to sound derisive, but this hardware completely defeats
the purpose of X/C Soar IMNSHO, although I'm sure it works as
advertised.
