Hello everyone.
I'm looking for a way to measure my heart-rate while swimming.
My main requirements are (please excuse my bad english):
The device has to display the heart rate while i'm swimming. I'm a newbie and need to see my heart rate during my training.
Optical heart rate sensors don't seem to be very reliable under water. Thus i would prefer a non-optical device.
I would like to spend under 150£ if possible
Thank you!
