Hi Udo,

The Themi can record 6 hours at 4 second intervals. The default setting is
15 hours at 10 second intervals.

It could provide NMEA output for a PDA, but it can't provide 5V power for
the PDA.

Good Soaring,

The Themi does not have any input for glider type or airspeed. It uses
GPS data and pressure altitude only for the thermal centering
calculations. Many reports suggest that it works very well.

Paul,
How many hours, with 4 second interval, will the Themi FR record.
Does it have a 5 volt output and cable to hook up a PDA?
