Healing mineral springs 30' from the center of Athens...

The Athens Vouliagmeni Lake!!!

Vouliagmeni means sunken and it is a small brackish water lagoon, that water comes from the mountain of Hymmetus.
After an earthquake the cavern collapsed probably during the middle age.
It continuous deep to the mountain in an underwater cave that it is very difficult to trace even by sonar.

The water temperature is 23 - 24 degrees Celsius 12 months a year and increases as far as you go further into the caverns and the cave.

For now the entrance to the cave is prohibited.

With the comfortable water temperature and the fish-spa, the lake functions as a year round spa too.

More about the lagoon here

Cavern Mapping Project

The lagoon has 4 big and deep caverns with crystal clear water and the maximum depth of each is 35 - 40m.

We will start the mapping of all the four caverns on Saturday 07/02/2015 and we will be conducting dives until the end of April.

This is an official invitation to anyone who is interested in cavern diving and who would like to join us and participate to this project.

This a great opportunity to dive the most unique place in Europe. Different kind of anemones, soft corals, fish-spa, warm water and amazing caverns are just some of the things you will enjoy in this place.

During the dives the participants will be supported with video debriefings, webinars, notes and seminars in order to help them to improve their existing knowledge and skills and to become even better, safe and thinking team divers.

For those who want to participate but have not yet certified as cavern divers, i will conduct two cavern classes, one in the beginning of the project 14/02/15 and another one on the 7th of April.

Sea Breaze will support the teams with cylinders, gases, sofnolime and additional equipment that maybe need.

The cost per dive is 30.00 euro

Included:

As you read our pages you will be confronted with a lot of ideas, opinions and information about closed circuit rebreathers. Non of this is intended to be used as reference or to replace a proper closed circuit rebreather training course. It is only our opinions. If not used right, diving a closed circuit rebreather can kill you. Even when used right rebreathers some times kill divers. It is your responsibility to obtain training, build experience and decide if you want to buy and dive a closed circuit rebreather. YOU HAVE BEEN WARNED!

Here you will see a different setup with minfold and 2m long hose. Just one quick connector with no need of gas exchange during the dive. These 5ltr tanks were just one choise for the test dives. You can also use up to 12s or S80s. The O2 is in a separate cylinder carying on the left side as a normal deco cylinder, connected to the quick connector and has an additional 1st & 2nd stage so to be able to use it as bailaout and deco gas at 6m.

Another point of interest is that with this this unit you don 't need kilos on the tanks for triming her and by herself helps you to stay in horizontal position in all phases (swimming, deco stop etc) of a dive. If you are interested for more informations, tips, tricks and courses, pls drop me an email at spyros(at)is-expl.com

2X5ltrs 232 steel tanks on the X-Plate
conected with manifold

2X5 ltr tanks on the X-Plate connected with the manifold. (back).
In that picture you can also see the exhalation tube that is into the canister

The head with the PPO2 handset.

The head from inside.
You can see the two O2 sensors and place for a third one for the DC.

The head. On top you can see the ADV that works as a normal 2nd stage. This is a big advantage as you can service and adjust very easy by yourself. On the left you can see the O2 feed and on the right the diluent feed. In front of the inhalation and exhalation holes you can see the cable that goes to the PPO2 handset and another hole that is for the DC. In case of you have an ADV failure just shut down the valve(s) as you previews learned to your OC technical class

The head from the side.
On the left the O2 feed that is a normal BCD - DRY SUIT connector and on the right the diluent feed that is a simple fixed elbow screwed on the ADVs second stage.

The left post with the diluent feed hose (the short one),
a normal second stage LP hose that goes to the BOV and an SPG with boltsnap.

The O2 block is the state of the art of the unit because it allows you to feed the unit with O2 with tow ways. 1st manualy by presing the button and 2nd by adjusting the needle valve that works like an orifice. The one hose (down) goes to the O2 feed on the head and the other one is connected with the O2 cylinder.

This is the right post with a 2m long hose for donating gas to an OOA diver
and a LP inflation hose that goes to the BCD

These are the counter lungs that because of they have the scheme of the human lumgs are helping very much to reduce the WOB and additionally helping to keep the chest area totaly clean. They are placed on a DIR one piece harness.

The breathing loop equiped wit BOV.

The right (as you wear it) mushroom that has a water block

The left (as you wear it) mushroom.

The BOV easy to service and adjust same as ADV, as it is another one normal 2nd stage.

Only O2 in this 5.8 - S40 cyliinder. It is equiped wit a normal regulator, an LP hose with the quick connector and an SPG. With this way you can use it for feeding thr RB with O2 to maintain your PO2 but on the same time,in case of bailout you can use it as deco gas at 6m.

This is how it looks at the end

WARNING: This is not the setup that you will learn to your class. It is just a trial setup that we conducted some test dives. It is not an authorized setup by the manufacture!!!
