I’ve a question for persons familiar with a [pulse oximeter](https://en.wikipedia.org/wiki/Pulse_oximetry#Indication). I’ve two and neither has a display that can be seen outside in bright light. Do you know of a make/model that can be read outside in bright light.

Apparently bright light will introduce an error.
