Q. Can a parolee who wears a waterproof ankle monitor immerse in a mikva Erev Yom Kipur or is it a chatzitza? If permitted, would the same apply to a woman’s tevlila?

A. Horav Shlomo Miller’s Shlit’a opinion is that if the tether’s band is not tight and water can enter and wet the skin, it is not a chatztitza for men or women.
