For those of you who swim (at a pool) on a regular basis, but either don’t have a waterproof pump or don’t like to wear it while you swim, what do you do with it? Do you leave it at home, put it in a locked locker, leave it on the side of the pool in a case of some sort, give it to a lifeguard or some other staff member, etc.?

I will leave it at home or in a locker.

Lock it in the locker.
