Used Volkslogger for sale - it came with a glider I bought recently
and I already have another logger. It is in full working condition -
these loggers have a very rugged construction. This logger is IGC
certified, perfect for your badge and record flights. It's wired up
and ready to go, just plug in and launch, either stand-alone or
driving an iPaq or similar PDA.
