We make scuba diving gears for your great diving life

Bism Technology

All Bism diving gears developed under "FREP" philosophy -- a solution which creates products after by users at the frontier of the diving world, continuously making break throygh in tough missions

NELEUS is the only regulator that has a 360°revolving second stage swing head in the
(Utility model registration No. 2078330)

The "swing head" is realized by the double swivel which can revolve 360°to the front/back and right/left. The swing of the entire second stage distributes the force that works to separate it from the mouth.

Bism's original design ensures the best feel of fit in your mouth all the time so your jaws and teeth will not feel tired. Ideal also for women or senior divers with smaller mouths.

The evolution of dive computes began as a dream.

セDive computers used to be large and heavy before -- used for making diving plans or recording diverse data including movements to higher places after diving, air travels and logs.
If we can wear a watch-size dive computer anytime anywhere -- the development started as a challenge to the unknown world.

We stick to "rustproof" and "lightweight" titanium parts.

We stick to

Among Bism series, all NELEUS regulators use titanium. Being half as heavy as copper alloy, the material is highly strong and friendly both to humans and the earth. This has been proven by the fact that it is used for deep ocean research vehicles investigating the sea thousands of meters deep, F1 machines, jet engines and space development projects including rockets.

Regulators are sometimes subjected to tough environments. NELEUS regulators have a beautiful form made of titanium, together with a flow control mechanism (FCV ) and a spiral flow system. They are the ultimate embodiment of the safety and premium quality divers have sought after.

Our pride in hoses

People have different heights and different arm lengths. So there should be different lengths of hoses for different people. From Bism, you can order a hose of a length personalized for you. Custom order hoses are also ideal for junior users. Order a length in the range of 500mm to 2,000mm in 50mm blocks. Delivery time will be about a week from your order.
