The XT1/XT4 Advanced Open Water Regulator Package pairs the XT1 first stage with matched, balanced XT4 second stages to deliver an exceptionally low work of breathing in a compact layout. Available in Yoke or DIN fittings, the package includes a padded carrying bag for transport and storage. The balanced XT4 second stages are tuned for smooth inhalation across a broad range of depths, making this regulator package suited to demanding open water diving.
