Are there any pool length requirements?
The goggles suggest some common pool lengths when you are starting your pool swim. You can also choose your own custom length.
Please note that the minimum pool length is 15 meters or 16.5 yards and the maximum is 650 meters or 710 yards.
If your pool is below this requirement, you can still use the goggles by choosing the Swim Spa mode on the goggles.
