Pulse oxymeters need warm fingers with a good blood flow to get a reading.
Clip on units like this require that you remove a glove to use it - not a
good idea in a wave. I'd pass.

I don't mind doing that occasionally, as I already stick a fingertip out
of my mitten to change the radio or poke the Ipaq.

I use a unit that has a sensor on a cord. The sensor and cord can go under
a glove. The display unit attaches to my arm with a Velcro strap.

Which unit are you using, and which unit do you wish you had? I've seen
the Minolta Pulsox-3, which looks ideal except for costing 2.5 times as
much.

How cold
can it get in a wave? I've seen -55F.

Not me. I like to stop around 0F, though I'll occasionally splurge and
go as high as -20F outside (it's warmer inside, of course). Even that
makes my feet cold and gets me worrying about the gel coat.
