■Deep diving

Let's go deep!

Experience dive sites that are a little deeper than the depths you experienced in the Open Water
Course.

Fish habitats such as sunken shipwrecks and beautiful soft coral formations are not always found in
shallow areas.

Experience the basics of deep diving.

Maybe someday you will be taken to the Dragon's Palace.


How to deep dive

Make sure you and your instructor are familiar with entry and exit procedures and
methods, underwater travel routes, dive depths and times, cues, each member's role, and what to do in case of an emergency.

Buddies should also make sure they know how to handle each other's safe seconds in
case of an emergency.

When underwater, pay attention to depth, time, air volume, and your buddy's behavior.

Also, be sure to breathe and move slowly so
as not to absorb more nitrogen than necessary.
