Is there any arm band compatible with forerunner 255 for use during swimming?
Me and my colleague, who has a Swim 2, are looking for it since the heart rate monitoring is not working as expeted. The issue is probably related to the way the software post process the raw measurement. We are experiencing low heart rate during strenuous exercixes or sudden high jump of heart rate during rest.
We would like to avoid to buy the thoracic band by Garmin since not so comfortable during swimming.
