I'm looking for someone in SE Wisconsin (or surroundings in Illinois) with whom to practice static apnea. We would meet at a public pool and safety for one another. I am not a freediving instructor but have trained in static apnea, and I am looking to maintain and improve my abilities. I know the signs of when a diver is imperiled, and what to do in these circumstances, and I can provide information about this to a partner as needed.
