If you see a DUI patch on a piece of equipment you know that piece of equipment will do something that no one else’s will - otherwise it would not be able to wear the DUI patch. This holds true for our Buoyancy Control Systems – the DUI DELTA and our new for 2003 the first ever non-weight integrated, weight integrated buoyancy control systems; Aurora and Intrepid.
The problem is that on a wetsuit diver the center of buoyancy is somewhere around their waist. The rubber is doubled or even tripled on their torso yet only a single layer on the legs. On a drysuit diver the center of buoyancy is over their hips. This is due to the diver wearing the same amount of insulation all over their body. This can make their legs feel more buoyant. Most drysuit divers using weight integrated BC’s try to compensate for this by wearing ankle weights. Think about this. If you were running would you wear shoes made of lead? Swimming, an equally demanding activity, demands proper ergonomics. Add a current to swim against and it is clear how unwise it is to wear ankle weights. After careful examination of this problem, DUI has made a corporate decision to change the design criteria for BCs. The combination of a BC with a weight system that can be adjustable for a diver wearing a wetsuit or drysuit. This combination allows the diver to put the weights at their center of buoyancy regardless of what they are wearing. DUI has accomplished this by using its Weight & Trim System with its unique line of buoyancy compensators. What is special about the 2003 models is that they are available at the same price as a weight-integrated BC. This unique configuration solves a number of problems: First, very few people can comfortably pick up a weight-integrated BC with the weights in it. Most Divemasters will not change your tank for you if you are wearing a weight-integrated BC. Second, in a conventional weight-integrated BC the center of buoyancy leaves a diver either head or feet heavy – which requires more effort in swimming, maintaining controlled buoyancy, attaining comfortable safety stops, higher air consumption, etc. In the DUI concept the diver picks up the Weight & Trim System and puts this on first. Then puts on their BC. The two units work together as one. DUI is challenging the diving industry to recognize the basic flaw in the design of the weight-integrated BC. This is a big step forward. In designing our BCs, DUI engineers have paid close attention to the details with two instrument retractors for your gauges and lights and bent “D” rings for easy attachment. They have also designed accessory pockets that the diver can actually see into. DUI has spent a lot of time in ergonomic studies to see to it that the harnesses truly conforms to the human body even to the point of designing one BC, the DELTA, to have infinite, quick adjustments. Just as DUI drysuits are in a class all of their own we invite you to test them and you will find that DUI Buoyancy Control Systems are also in a class all of their own. The reaction of the divers using them at the 2002 DOG Rally & Demo Days is nothing less than astounding.

The
modern BC is okay for most wetsuit divers but they do not serve drysuit divers
well. Keep in mind that approximately 90% of BC’s are weight integrated and,
because drysuit divers have more insulation, they require more weight.
