DESCO manufactures our own equipment in our Milwaukee shop. You may not think of a inland city as a hub of diving activity but Milwaukee has a long tradition in hyperbaric and diving science. The history is covered in detail on our company history page. Milwaukee was known as the "Beer Capitol" but during the war we also were known as "The Nation's Machine Shop". Virtually all the metal components of our equipment are fabricated in Wisconsin. DESCO has long standing relationships with many local suppliers.

Our longevity in the industry has resulted in DESCO making many friends and business contacts around the world. In instances where another companies products may complement our own lines we will forge alliances and offer those products along side ours.

Classic Diving Helmet Parts

DESCO is a recognized leader in supplying replacement parts for old diving helmets. Where an original part can't be found in many cases we can borrow a piece from a associate collector and have a reproduction cast from it. While the new part will be smaller than the original (due to shrinkage during the casting process) the new part will adequately replace the missing item.
