During the dive, you should do the following:
- Always dive with a buddy and with surface support.
- Take into account any currents or rough sea.
- Do not yo-yo dive (go up and down continuously). Do not exceed an ascent rate that is greater than 9 meters/30 feet per minute, and if possible, slow down in the last few meters or feet.
- Never hold your breath when ascending.
- Always carry out a safety stop that lasts 3 to 5 minutes at a depth of 5 meters/15 feet.
