Man... I got tangled in a voice comms line once because the guy next to me was narrating his whole dive like a podcast. Total mess. Sometimes the old hand signals were just cleaner, you know? You point, you go, everyone gets it. Now you've got wires and someone's crackly lunch order in your ear... Feels like solving one problem just makes three new ones sometimes.
My buddy Carl had a similar mess in a cave dive last spring. His comms unit picked up a taxi dispatch frequency, so we heard 'Code 3 on Maple Street' while trying to navigate. Right after that, he started using hand signals only, which @miles834 would appreciate. Saved us from a lot of confusion and static.
