Hi Douglas

I definitely think the product is worth the money. I asked Garmin about the
Glide Ratio function, I hope they can provide a fix. Nice to know that some
works are in progress for software related to our gliding activity.

Using some answers provided by different persons I am working on maps to get
SUA displayed on the unit, not an easy task but I hope to succeed, talented
people have developped very nice piece of software for free.

Gilles, I use a Garmin GPS 3 Pilot and also find the "glide ratio to
target" very useful. There are two minor problems with it (at least
on the 3P): It only displays a glide ratio when within 90 degrees of
the track to the target, which is a bother when thermalling or
searching for a thermal and not headed towards the target; and it if
using a user waypoint as the target, you must enter the arrival
altitude for every waypoint you select, instead of just using the
waypoint elevation, as can be set for an airport in the database.

I use it as a backup to my primary glide computer (an SN10); when I
see 25/1 I know I can run home at 100 knots!

Same problem with the jumpy glide angle, but with altitude being the
least accurate position in GPS, it's not too surprising. I don't find
instantaneous L/D very useful, anyway, since I prettymuch know what my
ship will average at various speeds. If it showed the average L/D
over the past 10 or 20 minutes, that might be useful.
