I like SCUBA Diving and swimming. I have been NAUI's SCUBA diving instructor since 1999. I enjoy to share my diving experience as well as my video taking that took in the last 20 years.
I visited various dive sites such as Cocos Island, Raja Ampat, Red Sea, The Bahamas Islands, Niue, Cendrawasih bay, Palau, Maldives, South Africa, Komodo, Bali, South Africa and Cocos Island.
I heard for a long time that Tung Ping Chau has an abundance hard
coral near its pier.
Tung Ping Chau is one of the
most remote diving sites in Hong Kong. It is not often that the diving
operators in Hong Kong offer this diving site.
On 17th September, I dove
there. We took one and half hour to travel there from Wu Kai Sha Pier. I planned
to have three dives on that day. Before I entered to sea, the captain showed a
map, which has an area marked as special region. Then I went there first to
explore what special it was. This area is a sandy bottom with some sea
anemones and clown fishes. I don't understand what the meaning of special is.
Then I turned to my target in
second dive. When I saw the area of hard coral garden, I have rated that it is
the best hard coral living area in Hong Kong. Many different hard coral species
and even families grow together in very heathy condition and larger area. I was
very enjoyable of this dive and didn't want to return.
When I have surfaced, they
yelled me to return the boat at once. I wondered whether an accident happened.
I asked them what happened to yell me. They said that they would change dive
site because this dive site had nothing.
Oh my god, it was because they
went to wrong area. I told them I saw the most beautiful hard coral area in
Hong Kong, but it was too late. The boat was starting to travel and leaving
Tung Ping Chau.
I was very angry that they even
didn't do a little bit research about the dive site.
I was the only one who saw the
beautiful hard coral.
I found that it was a so call
We travelled in such long
distance and time because of its beautiful hard coral. All this effort was wiped out by such a no sense hopeless instructor.
If you still remember what you have learned from your diving course, the intermediate pressure of the first stage is about 10bar. It means that a balance type first stage will supply 10 bar to second stage no matter how much air remains in the tank.
Will first stage supply air when tank pressure below 10 bar?
The answer is yes.
When tank pressure is below 10 bar, the piston will open freely.
