What reading you get before BO? SPo% 60 or more?I've worn a 'water resistant' pulse oxy meter on my finger during some DYN testing. I covered my entire hand in a bag, packed in some super absorbent fabric, and duct taped the whole mess around my wrist. Very awkward but it was worthwhile for me to get some readings for pool DYN. It is not suitable for diving and not really useful for safety since to get a reading you have to stop swimming/moving, position the oxy meter, and wait several seconds for it to lock onto a reading, all this while continuing your breathhold.
