Nitrox or Helium, either way, in sidemount!
For a while now, Nitrox (oxygen enriched mix) and or helium based mixes, aka trimix, have been the sole toys of technical divers. It is true in a way, and thanks God to these different mixes, man (ok, women as well!) are pushing the limits of scuba diving and helping understand the intricacies of deep, very deep diving as well as decompression models. If Nitrox is not new, nor is helium, they are still seen as ‘voodoo’ mixes.
