Imersion SARL was founded in 1989 by Mr. Pierre Buffa with the help of a French freediving spearfishing world champion. The place was Marseille, in the South of France, Europe's capital of diving equipment manufacturing.
In 1995, the French main manufacturer of shafts, diving knives and spearfishing accessories, Ets.Desiage joined forces with Imersion to reinforce its potential on the freediving spearfishing market. With the Coralign brand, Ets.Desiage was the sole supplier of Imersion for speargun accessories.
The headquarters and the main plant are in Thiers, a city located in the centre part of France. The city is famous for it s manufacturing of knives, and also for other industries such as high-tech plastic moulding.
For many decades, in fact since 1974, Ets.Desiage has been manufacturing equipment for the spearfishing industry, including major diving companies.
Imersion/Desiage has several manufacturing units in France. The spearguns, shafts, bands and spearfishing accessories are manufactured in Thiers where the fins, the plastic and nylon products are also moulded.
The commercial department is located in Vitrolles a city close to Marseille by the Mediterranean sea where all our products are tested.
Our large range of products has interest for several markets from the beach bazaar to high-tech equipment designed for competition, also our high quality products are distributed world wide. The group can also manufacture specific products under other brand names at client s request.

Imersion was introduced to the USA almost 20 years ago and found an untouched market for top European spearfishing products. Through DEMA trade shows, dive stores, and top competitors Imersion set the standard for top quality fins, suits, guns and accessories. Imersion has sponsored more top athletes in the USA and most of the world then any other company out there. Names like Mike and Glen McGuire, Dennis Haussler, John Plikus, Dave Douma, Dave Sipperly, Allen Speaher, Terry Mass, and John Ernst have all used Imersion.Imersion Teams have won the last 10 of 16 Nationals in both fresh water and salt water and Dennis Haussler has won 2 World Blue Water Meets using Imersion equipment. For the old and new Imersion is the product of choice. Kelston McGuire started shooting at 5 and now at 8 he is the youngest sponsored athlete, setting a new state fish record in Utah and starting to place well against much more experienced divers.

Imersion has time proven products, and is always on the cutting edge with the latest materials. They were amongst the first to use carbon fiber in guns, they have the most comfortable fin foot pockets, durable well fitting suits, and Fins that have always been top performers. I have personally used there product for the last 18 years and it has been the key to 9 national wins in salt and fresh water and 6 world competitions. My personal favorites are: the tri-ax gun for it quick turning speed, 7mm camo suits for the fit and warmth, the 3 finger mittens for their warmth, the new Carbon fins I can kick all day long. I look forward to diving this year in the NEW 10mm Ice Breaker suit which should be perfect for these cold rocky mountain lakes where the temperature can be just above freezing. Dive with the best forget the rest.
