Well, you definitely need a ClearNav, and a Butterfly and, heck, a new
ship to go around it. Why not? You only live twice.....

OK back to reality. I flew for years with GNII, IPaq and a Cambridge
302. Kind of like what you have now. Do you need to change just
because of electro-envy? Yep, lots of new gadgets out there.

The question is, what is deficient in your system that you want to
fix? You have a flight recorder in the Cambridge GPS 20 right? You
have navigation with GNII, right? You have an audio vario in the
Cambridge cluster right?

What might you be missing that would definitely make your soaring
better?

Maybe some upgrade of GNII? What doesn't it have? Thermal
assistant? Maybe better competition optimization? Color? SeeYou
Mobile has evolved since you last used it so maybe it is better now
but any of the new stuff is more complicated than GNII. Brighter
screen? The 1500's are pretty old tech but about as good as you can
get in bright sunlight.

Some suggestions;

- The Oudie is pretty nice. You could buy the lite one on the cheap
and install XCSoar or LK8000 for free. Or a used Oudie I.
- There is the Colibri II which is a flight recorder and navigation,
thermal assistant, etc, all in a very nice small package.
- FLARM - nice safety enhancement if you are around lots of other
gliders.

Or just save up for newer batteries or replacing your old parachute.

Others will have better reasoned thoughts.
