Since the introduction of the first production model in 1999, the KISS Classic has earned a reputation as the most durable, reliable and easiest to maintain closed circuit rebreather on the market. Due to its ability to be used in harsh, and extremely remote locations – which have included some of the deepest cave systems in the world – it has also obtained status as a true expedition-grade rebreather.
It was called the Classic for its simple straightforward configuration, with the rebreather’s head and scrubber centrally positioned on the diver’s back and flanked by the unit’s oxygen and diluent supply on either side. This layout follows that of the majority of rebreathers built today. The most outward differences between the KISS system and other non-military rebreather of the era was that the Classic’s two counter-lungs were back mounted instead of being mounted over the shoulder.
Classic Explorer Counterlung Case with Explorer Backplate
From the start, the Classic’s counterlung case has been an integral part of the system, serving as a protective shell for the unit’s two counterlung’s, a supporting frame for the loop and scrubber assembly, and a nesting bracket for both the oxygen and diluent supply cylinders.
In 2013, the Classic’s counterlung case was redesigned to provide greater access at the top. This allowed for easier installation and removal of the rebreather’s counterlung’s for cleaning.
The same update saw the addition of a new backplate design that was based on the original Explorer model released in 2010 but had some modifications. The new plate more closely follows the contours of the counterlung case to ensure the unit’s overall profile remains as close to the diver’s back as possible, creating the optimum work of breathing (WOB). This redesigned case also became a replacement item for Explorer models and the original Classic KISS.
This new counterlung case and backplate combo allows for a broader number of harness configurations and can accommodate a number of wings designed for either double tanks or CCRs. The Classic can also be ordered with a Dive Rite CCR XT wing (providing 40-lbs. of lift) and a Trans Plate harness.
