Pulse oxymeters need warm fingers with a good blood flow to get a

Clip on units like this require that you remove a glove to use it - not a

I use a Nonin earlobe clip on a flylead connected to a panel mounted unit.
The sensor can be worn under a hat or balaclava so the sensor and my ears
stay warm. Less interference with controls and can 'fit and forget' for the
