Pool swimming - counting laps algorithm

kamarasm

Hi Guys,

May I have somebody to explain to me the algorithm what S9B using for measure laps in pool swimming?
My question is that it can measure laps in case I’m not doing flip turn?

Thanks a lot,
Marcell

Not sure but I’d bet it is mainly based on the accelerometer sensor + perhaps compass. Even lap counting isn’t always very accurate, it works even if you’re not doing a flip turn.

@kamarasm yes of course. I can’t flip turn but am swimming from time to time in a pool. The laps count is based on the accelerometer.

You want to make sure:

that you firmly push away from the wall and have some gliding phase. This will ensure to get the turn registered.
you don’t get interrupted too much during the lane (like stopping and waiting for things to get out of the way), as this could introduce extra laps.

Thanks a lot Guy, it was really useful.
I hoped Suunto figured it out as carefully as they used to.
