The Dive Rite Suit Inflation Regulator is a must for divers using trimix based gases as mean of providing a insulating gas to their suit. Gas mixtures containing helium are really poor at keeping you warm as such you want a small cylinder of air or argon to inflate your suit with. A dedicated first stage such as the Dive Rite Suit Inflation Regulator allows a more precise volume of gas to be added to the suit as they are tuned to a lower interstage pressure than a normal first stage. As they only need to provide low pressure gas the valve can also be much smaller, reducing bulk and weight which helps to improve streamlining. The Dive Rite Drysuit Inflation Reg also includes a low profile overpressure valve just in case the valve fails to release the pressure in the system rather that over inflating your suit. Fits any 232bar cylinder.
A neat alternative to suit bottle mounting can be found here.
