To all Divejohor Family members  ...

Today i would like to introduce to you one of the greatest underwater pioneer and explorer .

Here is a brief history of all the great things Jacques-Yves Cousteau gave us .

During the 1940s, Cousteau is credited with improving the aqua-lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur.[7] Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan.[8] In 1943 Cousteau tried out the first prototype aqua-lung which finally made extended underwater exploration possible.

LegacyCousteau's legacy includes more than 120 television documentaries, more than 50 books, and an environmental protection foundation with 300,000 members.[17]

Cousteau liked to call himself an "oceanographic technician." He was, in reality, a sophisticated showman, teacher, and lover of nature. His work permitted many people to explore the resources of the oceans.

His work also created a new kind of scientific communication, criticised at the time by some academics. The so-called "divulgationism", a simple way of sharing scientific concepts, was soon employed in other disciplines and became one of the most important characteristics of modern television broadcasting.

Cousteau died on 25 June 1997. The Cousteau Society and its French counterpart, l'Équipe Cousteau, both of which Jacques-Yves Cousteau founded, are still active today. The Society is currently attempting to turn the original Calypso into a museum and it is raising funds to build a successor vessel, the Calypso II.

Hi Guys ...

I have used the Bio Fin pro now for 4 years and can say that it is worth the money i paid for .It has no memory effect ,is highly durable and doesn,t fade .I have yet to change my fin straps after more then 500 dives .I have also been recommending this fins to divers with a weak fin kick .The result is a faster learning cylce and a better stronger fin kick after a short while .

Hi Guys ...

This is a short intro for the Scuba Pro MK 25 S 600 a high performance scuba regulator which i used for many years .

Our top performing balanced piston first stagepaired with our high performance air balanced second stage; thiscombination is SCUBAPRO's most popular regulator combination. TheS600 truly matches the  MK25's characteristics and thanks toits adjustment possibilities, it adapts to all diving conditionsand all diver preferences. Ease of breathing is the essence of this system.

The MK25 first stage is our absolute top performer and is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air.  The means instant air flow at any cylinder pressure and water temperature for a real care free dive.

Paired with the air balanced high performance S600 second stage, this system is our top performer.

Balanced flow valve provides constant & effortless airflow.Diver adjustable inhalation control enables personal adjustmentof breathing effort.Diver adjustable Venturi Initiated Vacuum Assist (VIVA)dive/pre-dive control switch and extra high flow exhaust valve account for easy inhale & exhale.

Super-flow hose for smooth air delivery.Precision moulded, lightweight components and anti-freezematerials provide high corrosion resistance and enhance cold water performance.

Hi Guys ...

Our recent dive trip to Sipadan Island was great fun .

We had a chance to see huge schools of Barracudas ,Big Eye Jack Fish and Bumb Head parrot fish .

As Sipadan is famous a famous spot with Turtles ,we saw plenty of them .

They came in baby and grandmother sizes .

Some of the group member did a Deep Dive specialty on the Trip ,which enhanced the experience .

As Sipadan has many drop off and wall dives ,we could easliy punged to 40 m and to do our deep dives.

Here the students encountered a totally different environment with huge Sea Fan and cruising reef Sharks on the prowl .

Please feel free to share your experience of the trip
