Gerhard,

I bought a Nonin oxymeter about four years ago and really like having
one for several reasons:

I have a Nonin oxymeter and find that it has a real visibility problem in
the cockpit when under full sun. The problem is that it uses a red LED display
(remember those early digital watches?) rather than an LCD display. Otherwise,
it is an amazing device.

While these portable units are good for occasional checks, a panel mounted
unit with an ear clip might allow continuous monitoring. Another idea (Bose are
you listening?) include an oxymeter with an audible alarm in an aviation
headset.

This is a link for oxymeters that showed up here a few months ago.

with them and have no connection.
