It’s a pity that it does not work in open water.
why so? speed and pace obviously wont as they come from the accelerometer detecting push-off in a pool.
It’s on their website that it works only in a standard 25-50 pool. I guess their AI algorithm relies heavily on pattern ‘reset’ with every turn at the end of the pool so that it can stop guessing what’s going on and start afresh.
