PAA: Fascinating, he misrepresents R’ Uziel as well. That’s important.
I saw an Eitza from a YCT graduate that might actually work, by the way. If you put a button on the bottom of the Mikvah (that is impossible to reach without being fully submerged) that rings a bell outside the room when pushed, then it could be that according to most Shittos the B”D hearing the bell is just as good as R’iyah. It’s certainly a better idea that what either Katz or Fox has said so far.
