I am using a Polar bluetooth H7 with a link up to Polar beat, which works without problems in dry conditions. Once the sensor is immersed in water, a signal interuption occurs, and heart rate monitoring ceases to function. How does one then monitor heart rate underwater via bluetooth Polar sensor? Polar states that using the heart rate sensor in combination with the watch should work, however, in our lab, that has not seem to work either. Is it possible to go cableless while monitoring heart rate underwater, or is the solution good old EKG cables?
Principally any Polar heart rate monitors using either one a T31 coded chest strap or a regular Wearlink chest strap will work and then the Suunto Memory belt and that is it. Those are the only ways I know of to get continual heart rate while swim training. The Swimovate Poolmate swim watch is a great solution for counting laps and strokes
Your problem is a strange one - why does it need to be bluetooth? The T31 strap works in water but pairs with a different watch. If you are simply recording every x time period then its a relatively cheap fix... However, if you wish to continuously monitor over time (say every second) then you'll want to spend some more money. A top tip might be to look at what swimmers/triathletes are using in their daily training activities. If bluetooth is crucial then there are other options online for about £25.
Hey Michael. Why Bluetooth? Well, for one, I would like to eliminate cables during my measurements. Yes, as a backup, one can always use a cable EKG to monitor heart rate underwater, however, just wondering if one could simply bypass the cable problem via Bluetooth. As Phillip stated, one may have to improvise, and just experiment with what I have. Maybe with some luck, the bluetooth option may work.
Dear Sir
Now a days wristwatch based stored can be tried because it is water resistance. only disadvantage is that you will not be able to see it in action. pcg,Chennai
