I tend to agree with Marcel. I also fly with an ILEC SN-10 and an IPAQ
with Winpilot. My sense is that algorith and precision from the SN-10
is always more accurate than Winpilot. The reason I say this is the
same as what Marcel mentioned, which is the ILEC is capable of
calculating windspeed and direction while in level flight, whereas most
other software/computers require you to be circling.

Doug,

I'm curious to know how much variation you get between the two, if any.

I use WinPilot Pro 6.x and an LX7000 Pro, and the two wind indications
are usually very close.
