    General examples of diluent gases that can be used in rebreathers include: air, nitrox, trimix, and heliox. The MKVI is in its recreational configuration limited to 40m / 130 feet depth and uses only air as an allowed diluent, following established compressed air scuba sport diving practices.

    Please note that the Besea harness and the 11-inch adapter are both sold separately and are not included in the Poseidon MKVI. The pre-packed scrubbers are consumables and are sold separately and not included in the MKVI. Standard tank band supplied with the MKVI, quick release buckles on the items sold separately.

    This is to allow more experienced divers the choice of using an existing personal backpack, harness, and buoyancy compensator. Poseidon supplies the tightly-integrated Besea, harness, and buoyancy wing system for use with the MKVI. The front extrusion rail on the Poseidon MKVI accepts the 11-inch adapter (see Figure 1-13). Attachment of the Besea is as quick as aligning the 11-inch adapter pin-bolts to the upper holes in the Besea harness as shown in Figure 1-13.
