In case of a technical problem act according to the instruction!

Diving is one of the safest kinds of active rest if you follow the diving rules and make a timely maintenance of your diving equipment. However it is impossible to completely exclude the possibility of a technical faulty that is why a diver has to know how to act in case of emergency under water.

Failure of second stage of regulator being under water

Respiratory system of a person operates only when the pressure of the air delivered to the lungs is equal to the external pressure on the body. The difference between these pressures cannot be more than 14%. Second stage of regulator provides this equality when the air is supplied. In case of its failure you need to come to the surface using an alternative air source. Usually it is an octopus of a partner’s scuba. It is an additional second stage with a long hose. In case of emergency both divers can breathe in turn using one scuba on their way to the surface.

A breakdown of a regulator may occur due to its blow on underwater rocks. In such situations a diver has to be ready to solve the problem.

A jammed inlet valve of a buoyancy compensator

To try and unblock the inlet valve BCD, you should unplug and plug back in the feeding hose. If all the attempts of restoring the functionality of the valve that provides the air supply from the regulator are unsuccessful then a compensator can be inflated through mouth. Former generations of buoyancy compensator were design for this kind of usage.

Detached connecting pipe of a feeding hose from an inlet compensator valve

In such case connection of the details has to be restored. Sometimes in such case the valve is jammed in an open state, which is indicated by the sound of air leaking in the water. That is why it is important to stop the air feeding from the cylinder with the help of a stop-valve. Then you need to try and restore the functionality of the valve, attach the connecting pipe and open the air feeding.

The difficulty of the operation is connected to the uncomfortable location of the stop-valve behind the diver’s back. Only some divers with long arms and good mobility of joints can reach it. Diving partner can help block the stop-valve. If it needs to be done singlehandedly then you should loosen the waist strap and move the cylinders closer to the head. Not to face such problems some divers prefer to install them behind the back stop-valve facing down.

Dislocation of cylinders

Most divers attach their cylinders to the compensator using plastic clinches. If you haven’t checked the safety of the attachment then it may be loose and a cylinder may slip out. To try and put it in the right place you will have to take off the compensator. It is much more convenient to use the help of a partner. Holding the cylinder with his knees he will be able to fasten it tightly in the clinch using hands.

Being under water, pay close attention to your partner and follow instructions.

5 rules of more efficient underwater orientation

Diving is beautiful, interesting, fascinating and surely dangerous. It is necessary to remain calm under water, properly execute all the operations and not get lost. The last one is quite difficult because every sportsman can have trouble in finding the way back. In this case staying calm is quite difficult. And to prevent this, one needs to know the basics of underwater orientation. It is the knowledge without which diving training would not be complete. So, what rules do you need to follow?

Rule No.1: learn the environment

Orientation should begin before going in the water. It is very useful to have special literature that describes the area. Maps are ideal for this. It is even more important if you do not dive together with your partner. One more option is diving off the rented boat. It is more convenient because in this case there is a supervisor that has valuable knowledge. It is important to listen to and remember everything that he says. Usually professionals tell about the depths and currents and help the sportsmen make a plan of actions. Definitely discuss all the key moments, mark the time or pressure to be the point of return. Thorough preparation to the process is half the success. Do not forget that before this stage is preceded by a process of checking the diving equipment for efficiency and wholeness.

Rule No.2: follow the guide

One of the divers has to act as a guide – in such case discipline and consistency are the best assistants. It is necessary to split the responsibilities: the guide leads the way and the other diver minds the distance, time and depth. This strict cooperation will prevent you from missing something important.

Rule No.3: choose your diving spot thoroughly

If we are talking about diving off a boat, than it should be done right in the place where the boat is anchored. When the place is chosen is should be reached on the water surface missing the waves. These simple rules work for absolutely all places including diving in Eilat or any other place.

Rule No.4: remember orienting points

Experienced diving trainers advise the beginners to pay more attention to the natural orienting points. These are objects that are fixed to one place and can later show the way: corals of different kinds, sand spots and rock formations. The key is not remembering the existence of an orienting point, but precisely memorizing its features and peculiarities. The more information you get on the way the easier it will be to find the way back.

Rule No.5: time estimation

If you properly plan the time and follow the above mentioned rules, you will not face any trouble. The time span, during which the diver swims off the initial spot, is determined beforehand. As soon as the time is up, the diver needs to turn around and swim backwards. In case of a current, it can be used in the beginning of the way. However this fact should be minded during time estimation of the time on the way back. Besides, divers mustn’t forget the golden rule of “the third”. It implies that one third of the air is spent on the way from the initial point, one third is spent on the way back and one third is spent on exploring the area around the boat as well as on decompression stops.

If you follow these simple rules than diving in Israel will be without any problems or stress. You will be able to fully enjoy the given opportunity and get loads of positive emotions.
