It was 1935 when the fertile imagination of Elio Toschi and Teseo Tesei was born the first SLC (Slow Speed ​​Torpedo). The first specimen was subjected to the tests in the tank since October 26, 1935 and then take to the sea in November of the same year. It seems that such means have often been reluctant to be controlled by pilots and that not infrequently presented of plant breakdowns which have, and it is perhaps because of their bad "character" that you have the nickname under which the S.L.C. (Slow Speed ​​Torpedo) have become universally known. It appears that Tesei, during an exercise to cut a network, annoyed by the continuing problems of the SLC, has ordered his copilot of "tie the pig" From that moment the S.L.C. becomes for the underwater intruders simply " the pig ".

The Beginning


The company T.G.W. s.r.l. arises from a synergy between two companies that was  operating for twenty years in the design and development of special automation and customer service of known brands of machine tools.

In this context we find two generations of diving instructors (Graziano Brenna and Walter Dal Pan) who comes at different times before to recreational diving and then to the technical and found often in the use of equipment limitations sometimes functional or just for comfort.


The decision to undertake the production of diving equipment comes from twenty years of passion and experience, which led us in the years to try what the market proposed, often thinking that certain technical details could be improved to help the divers


So we decided to design and build equipment with features and construction materials that were in our opinion the best compromise for this rapidly evolving world requiring high reliability, ease of use and low maintenance.


All this has made possible the creation of a company that allows us an easier way to the development and an easier and more controllable realization of these products.


WHat's Teseo

Teseo is an innovative dpv (or best defined underwater scooter) type tow behind.

We explain our decision to develop tow behind. The type tow behind is in our opinion the most functional as it has big advantages without compromising driveability use and power even in tight spaces with greater convenience in the transportation and logistics deployment as would be the case of diving expeditions.

The way of use and the size carry the TESEO conformation to greater hydrodynamics allowing us to drive more quickly and accurately.



One of the winning features of the development team of the range products Teseo is the fast implementation of a scrupulous process of problem solving from whom all the ideas that have transformed in a short time our products into something technically advanced and unconventional.

Go Further !!!

The expectations about  the functionality, design and product reliability are constantly growing. Often, to be successful on the market, precision and efficiency in production are decisive.

We create new trends and set ourselves the highest standards.

Teseo has known  all the technologies from electronics to advanced mechanical modeling.

Promises optimal performance; also provides a complete package for the entire life of the products, as well as to support customers with the most modern systems in the industry.

TESEO ... Achieve more ...Go further !!!


TESEO is dedicated to all those technical and recreational divers who want to increase their ability to explore optimizing the most of time underwater imposed by the strict rules of decompression and diving safety. In the image to the right you can see a technical diver with decompressive gas.

Surely this configuration brings definitely a lot of advantages but I find that the biggest difficulty is moving. Imagine having to explore a wreck or even just a new rock or a cave.

The only thing that binds us to the surface is the lifeline or line guide on which we went down and along which are positioned all the bailouts and decompressive gas. A wreck however small can force us to a big effort during both the exploration and during the return not to mention the cave that forces us to retrace much the same portion of the path for the return.

If we tie all this to the constant depth and variables such as current and emergencies can see how limited our exploration is definitely not counting the effort that in any case we will be doing.
