Every life support package should be equipped with the C-Phone HE4R Helium Unscrambler Communications System. The HE4R Unscrambler is unparalleled in its’ ability to decipher the helium speech associated with deep diving.

It uses a powerful digital signal processor to concurrently process four independent speech channels, whereas other systems mix the inputs together before putting the mixed signals through one unscrambler channel.
