Don't be misleading.

If someone tries to claim a badge using an EW and a
'mouse type GPS' it will be rejected. The IGC approval
of the EW barographs requires the use of a GPS off
an approved list. The approved list GPS's output a
proprietary NMEA sentence for selected map datum which
is recorded by the logger to stop people displacing
turnpoints by changing map datum in flight.

I'm not saying this is the way it should be, there
is an argument for COTS loggers, but this is the way
it is, you can't claim a badge with an EW and just
any old GPS.

This badge&cheap GPS issue come up year by year.
