I have owned an oxymeter for many years, I aquired one as part of my basic kit when I worked for a national Nursing agency just before I retired. I found it very uesful, mine is an Oxywatch, they are quite expensive to buy, but can be relied upon for accuracy, and also give other digital readings such as mini ECG and pulserate. The original one cost around £95, but you can now buy similar for around half that price. Take a look on the medical supply websites rather that places like ebay or amazon, they are more lightly to stock better quality more acurate machines for proffesional use, rather than just a gadget for athletes and fitness fanatics to check there own levels where accuracy is not so important than when used in a medical emergency.
Its also useful to buy one that comes with a case and Yanyard, they are fiddly little things that can easily be droped and lost when solo!

I have just taken delivery of a Pulse Oximeter. I ordered it off Amazon, it was about £24 approx (my memory is awful). It works great, just put the batteries in, pop it on my finger & it gives both my pulse rate and measures my blood oxygen saturation levels. I purchased it after seeing on tv that low blood oxygen levels can be an early indicator of Covid etc. I'm happy with the purchase, I have mild asthma but not COPD.
