Pre-planning can be carried out at home or in the dive centre, where they define:

1. Diving goals.
2. Choose where we’re going to dive.
3. Equipment needed for diving.
4. Access and transport to the dive site.

1. DIVING GOAL

---

The first care to be taken when planning will be the goal of diving. In fact we can distinguish among others: training diving, diving for the experienced, diving for photography, scientific diving, etc., each of them with well-defined characteristics and deserving therefore of planning according to them.

2. SELECTION OF THE DIVE SITE

---

When choosing the dive site we should be careful:

• The qualification of the divers.
• The possible interdiction by the maritime authority from the dive site.
• Accessibility. In this respect, account should be taken of the place of entry and exit, in the case of a dive from land, the choice of alternative exits should be taken into account in case there is a change in the state of the sea that prevents the originally planned exit.
• The visibility of the water, the existence of currents, the movement of vessels to the surface, the height of the tide, the existence of networks in place, the state of the sea, weather conditions are important factors to consider in the selection of the dive site that may lead to its cancellation and possible change of the same, always giving priority to safety.

3. EQUIPMENT NEEDED FOR DIVING

---

It is according to the diving objectives and the characteristics of the dive site that the choice of the most suitable diving equipment is made. The diver must make a list of equipment organized as follows:

• Basic Diving Equipment :
  • The mask, tube and fins are usually equipment that we do not alter depending on the objectives and characteristics of the dive site.
  • The fact will depend on the temperature of the water at the dive site.

• Autonomous Escafandro :
  • The bottle can be chosen in different volumes, weights, types of taps.
  • The vest may be coat type, the most common or type asa, more directed to scientific and or technical diving.
  • The set of regulators, consisting of main regulator and emergency regulator or octopus (2nd floors) and 1st floor, for CMAS One Star Diver divers usually this equipment does not need to be changed depending on the objectives and characteristics of the dive site.

• Miscellaneous Diving Equipment:
  • The manometer, the profundimeter, the watch, the flashlight, the knife and the whistle are equipment that the diver must carry regardless of the objectives and characteristics of the dive site.
  • The surface buoy with alpha flag is mandatory if the dive is carried out with exit from land.
  • The porch buoy, although the diver CMAS One Star Diver does not perform diving with landings, is advised to signal the place of climb of the divers.
  • The compass is also a recommended instrument for guiding the diver on the planned underwater route.
  • The dive computer is an equipment that may have integrated several instruments such as the manometer, the profundimeter, the clock, the algorithm of the dive tables that can integrate all the necessary calculations of the planning.
  • Other accessories such as underwater writing board and equipment carrying bag may also be included in our equipment list.

4. ACCESS AND TRANSPORT TO THE DIVE SITE

---

According to the objectives and characteristics of the place that we will perform the dive, we should think about the conditions of the place where we will equip ourselves, which can be in the diving center, on the beach, in the car park, on the boat, etc.

As well as the means of access and transport to the dive site, which can be by exit from land, with or without travel that requires travel to surfaces or using a vessel that will take us to the dive site.
