Thanks scotty! I've only been to 32m but that was already dark enough for me to feel panicky with the pressure squeezing my lungs to 1/4 the usual size, but at 71m her lungs would have been at 1/8 the size, like a size of a tennis ball..or maybe even smaller.. 😱

😱 is the right expression lol. I've done a few night (scuba) dives and it's so weird getting that feeling of losing your bearings, not knowing which way is up or down. Your stuff is next level.
