Philipp Rosel on Instagram: "Do you get less tired using nitrox? Which one do you prefer? 😊 If you don't know yet what Nitrox is you should check it out. It helps you to stay at depth for longer since you have a different mix in the tank and consume less nitrogen with every breath you take in. So the big advantage is to have a longer NDL or a shorter surface interval 😍 If you want to do the Nitrox course let me know :) We can do it even online If you want to join me on a trip let me know ☺️ Di
