For snorkeling, many people's impressions are still based on the use of mirrors, breathing tubes, fins, life jackets, floating on the water, and water activities where the head is buried in water to observe the underwater landscape.
However, this is a misunderstanding. Snorkeling is not only an activity that floats on the surface of the water. It includes the techniques of flotation, dive, ascent, drainage, ventilation, breathing, self-help, and equipment selection and use in order to ensure safety. Still need to learn.
The other is that every year snorkeling accidents or even loss of life, the probability is much higher than scuba diving. So don't take it lightly.
Like the title, I would like to agree with the classmates who do their homework and carefully assess before starting.
Because snorkeling basically has no barriers to entry, many local service providers are also very easy to enter into this activity, resulting in an uneven quality of service. Because snorkeling it looks very simple, as if only provided snorkeling 3 treasure, then send a life jacket can be played. But I want to say, this is not very reliable!
For snorkeling, the PADI system is included in the course content. The development of courses/activities must strictly comply with relevant standards.
The first point, the title owner can use this provision, when choosing a snorkeling activity provider, consider the snorkeling service provided only by the submersible stores that are only involved in the standardized management and is responsible for the normal operation. The first step.
The second point to note is that before the event, you have the right to consult the person who led the team, what the qualification level is, and how many people are responsible for taking care of the lead.
Take a look at how snorkeling can be a standard activity. For those who lead the team, the PADI regulation must be a diver with a level greater than or equal to the length of the dive. When it is open to the water, it can be understood as a divemaster who does not bring more than 10 people. The proportion of people dropped to even lower levels. The place of activity is usually on the coast of the island or near the resort where the water is relatively shallow, but there are a lot of coral places (of course, the water depth still can not stand), and where the service is good, there will be special dedicated snorkeling In the waters, no ships can enter this area.
The third point, the basic steps for snorkeling (outline)
1. The divers who led the team's divers and above will introduce participants to the basic equipment for snorkeling and their methods of use.
2. The team leader will bring the participants into the water by suitable means.
3. In places where the water is relatively shallow and calm, churches use such techniques as breathing tube drainage, fins kicking water, diving to keep distances, and even "digging into the water" dive methods, and of course the use of buoyancy adjustment devices - BCD (behind Let's start again)
4, then take it to a deeper place for snorkeling.
You have the right to ask the leader to teach you these necessary skills.
The fourth point, equipment that snorkeling should provide
1, mask, diving mask, will cover the nose
2, breathing tube, mouthpiece complete
3, fins, usually do not get used to how to use, but your leader will teach you how to kick the water
4, BCD!
According to the PADI standard, snorkeling is required to provide a buoyancy adjustment device, that is, BCD. This we are also called saliva shoulder, hey! That's right, it's the adjustment device, which means that buoyancy can be changed!
The leader needs to teach you how to wear it, especially if all the straps are fixed in a reasonable position, so as to ensure that the BCD does not drift, which in turn causes people to press underwater and cause drowning.
The team leader will also teach you how to inflate and use the deflate valve to deflate (convenient dive).
Here I talk about the situation of many snorkeling service providers using lifejackets instead of BCDs. I think it is unreasonable. When participants wear lifejackets, they can basically not dive, and the lifejackets are all coded and cannot be resized like snorkeling BCDs. Displacement can easily cause the lifejacket to press the person down, but the user does not have the ability to get out of the trap.
The fifth point is that snorkeling places are often in the tropics. The sun is fierce and the sea is unobstructed. Snorkeling also floats on the water most of the time. It is very prone to sunburn. If possible, rent a rubber diving suit as much as possible. Warm, protective and buoyant.
Sixth, a reasonable assessment of their own water. Although PADI does not say that you can't swim without snorkeling, you still have to evaluate your swimming ability. If you really can't swim but you want to try it, and the team leader explains the situation, you need more care. Stay with your buddies. The other thing is to decide whether you need to continue according to your comfort level when you are in calm waters. If you really don't feel at ease, spend more money and ask a special divemaster to take care of you.
The seventh point is to protect the underwater ecology. Do not touch any underwater creatures. If you really need to stand up, do not step on corals and step on sand.
