Paolo lives in Trieste and came to my house last summer in 2008, talking about Pirelli’s and homebuilt units. After his visit he send me several emails and even Pirelli spare parts for my collection! This page will not be the last we hear about Paolo. He is now in the progress to restore his fathers Pirelli oxygen rebreather. IN the mean time he bought a OMG rebreather. But this page is about his “little red home made rebreather”, a nice example how to build a nice diving apparatus with little materials and money!
Paolo test dived the unit in the swimming pool of his friend who also owned an old water pit. For his friend the 3 meters of depth were a true problem, but not for Paolo. Together with the family they dived the pit. He took all precautions for a safe dive and managed to reach the bottom. There he found incredibly enough after 94 years a German WW1 and a Italian WW1 helmet on the bottom.

Paolo dives his rebreather also in Croatia. There the use of closed oxygen systems are not allowed. He then uses  a package on his chest with the rebreather. In the water he then unfolds the rebreathers and enjoy the dive! I hope you like the pictures as much as I do. Paolo promised me to show me the progress of the old Pirelli unit. To be continued.. ;)

Here Paolo descends in the old Italian water Pit with 3 mtrs of water, not having an idea what to find.......
The first find: an old WW 1 german helmet!

Paolo Bertoncin’s “little home made oxygen rebreather” is a nice example that diving is in a man genes. Paolo’s father was a XMAS Italian war hero, diving oxygen rebreathers during WWII. It was a great pleasure meeting Paolo in my house in Holland. There  we had a long and most interesting conversation. I hope we will be able to keep in contact talking about our shared interest. My next visit to Italy will include Trieste ;)!
