Equalization System   The Equalization system can be found in the oral nasal cavity and is easily adjusted.   You will notice the block has two adjustments. You can use either the low or high position. The wires are in the low position in this picture. Additionally, you may notice a pad sitting on top of the block. It looks like a "V". You can see the legs of the pad protruding on the lower part of the block. We supply a few pads in different thicknesses. This is to ensure that you can easily equalize no matter what size nose you have!   Everyone has a little different face. As divers you all know how important being able to equalize is. Equalizing is a challenge for all full face masks One size does not fit all!. In order to ensure everyone can equalize, we have put together an Equalizing Kit which comes with every Guardian full face mask. The kit consists of two bases. One is a standard size without any holes. It can be adjusted up or down to fit as necessary. The other base has two holes which allow for different size pads that can be added. In the event the standard base does not work for you, one of the pads and the other base should fit the bill.
