What percentage of you out there use a handheld gps and / or
transceiver when you are intructing or just flying alone?

When doing IFR instruction in a plane without proper electrical system
redundancy (which is most light piston aircraft) I consider a battery
powered GPS a no-go item. Lose the master contactor, and the plane
goes dark. If you can't see the ground, you've just bought yourself a
major emergency. On the other hand, with a handheld GPS and good
batteries, you're still OK to shoot a non-precision approach.

I don't bother with a handheld comm. Unless it has an external
antenna, the range is very limited, and in any case there are
procedures for lost comm.

Of course VFR, I don't both with comm or GPS.
