Hi Gilles,

I used a 76s for a while, a very nice handheld unit . . but I've
moved on to using an HP iPaq H5550 Pocket-PC with WinPilot. If
you're inclined towards computing, this will give you much more
satisfaction. You can still use the 76s as a GPS source, or sell it
and buy a 'mouse' gps with battery backup. The Garmin has lots of
user fields that are fun to play with for awhile, but it really is
very rigid in it's design. A great general purpose device for
someone shy of computers. Best thing about having a Pocket-PC is the
remarkable uses they offer every single day!

Cheers,

Jim Kelly

Hi,
I'am not quite sure this is the right forum to post my question, let
me try
(I also found some specific gps forums)

I just bought a garmin gpsmap 76s mainly for use in a glider (hence
the post
in the current forum)

I wonder if someone has some experience with such device for two
points.

First point: I bought it because it has interesting feature such as
glide
ratio and glide ratio to target. The latter is perfect, but I found
the
glide ratio function difficult to use or at least difficult to take
advantage of. The calculation seems to be done on instant value
without any
"smoothing", as a glider moves a lot the result can vary from very
low value
to glide ratio higher than 500!! within a couple of seconds. Have
you
experienced such behavior? Is this a user error? A bug?

Second point: to draw airspace zone it seems possible to use
waypoints and
routes. Do you know other possibilities? Using a mapsource format
compatible
for instance

Thanks in advance for your answers
Gilles
