@christian-schmitt I think there isn’t one. But you can choose the regular mode and edit the distance afterwards, right? I mean, distance = flow velocity* time. Sure, it may be annoying, but as a workaround…

@mvpereira I used a Polar OH1+ (which is fundamentally the same as the Verity) by wearing it on the same wrist as the Ambit3 and found that the signal travelled 2-3cm under water and thus the connection remained if I wore them close enough together. I’m now using a Fenix 3 on which Garmin have disabled recording of HR when swimming and I use the OH1 in recording mode, export the file from Polar Flow after the swim and then add it to my swim workout in TrainingPeaks - TrainingPeaks then combines the HR and the swim details from the Fenix 3. Either option should work for the Ambit3.

@isazi thank you very, very much - it looks like that has worked! It’s nothing like as straightforward as Garmin but hopefully I’ve got there in the end. The test will be on the openwater swim tomorrow!
