Kiss Explorer Manual Closed Circuit Rebreather Review

Overview

Owning a scuba rebreather isn’t so much of a problem as is maintaining it. The Explorer rebreather from Kiss has long earned itself the reputation of being one of the easiest to maintain closed circuit rebreather around today. Aside from easy maintenance, it also has the attribute of the most durable and highly reliable rebreather a scuba diver can have. Specifically designed to withstand extremely harsh conditions, the Explorer is a super-strong and highly competent rebreather that any scuba diver should have. In our Kiss Explorer mCCR review, we highlight the great attributes of this great rebreather while touching on some of its pros and cons too.

For divers who want to have some serious deep water diving into harsh locations like wrecks and caves, the Explorer is a choice option for such endeavors. Whatever the requirement for your expedition, you can be sure that the Explorer can conveniently accompany you and avail you the best of breathing experience while underwater.

Crafted with really simple yet dynamically tailored configuration, the Explorer’s head and scrubber are optimally positioned at the back of the diver while the oxygen and diluent supply tanks are stationed on the sides. This positioning, like most high-grade rebreathers, helps to achieve an uninhibited and smooth breathing experience while underwater. Unlike most rebreathers though, this one has its counter-lungs situated at the back (back-mounted) as opposed to the shoulder-mounted ones around.

Kiss Explorer mCCR Review

Seeing much improvement from the original design, the counter-lungs on this rebreather is now enhanced with a robustly designed backplate which allows easier set-up and dissembling of the counter-lung for more natural cleaning. The backplate now sleeps smoothly on the back and body of the diver while aligning with the contours of the counter-lung to give a well-fitted rest on the divers’ back. This ultimately allows the scuba diver using the Explorer to have a better-optimized breathing work throughout the dive session. With this also comes a more robust harness configuration which accommodates wings used either for a dual-tanks expedition or a closed circuit rebreather.

The Explorer has an Axial scrubber design that makes the used gas to follow a course through the center tube and finding its way up through the scrubber that extracts the carbon dioxide from it. This type of scrubber design is highly resistant to much channeling, and it is much easier to pack and monitor. The head of the scrubber is attached to the central spine of the case for the most efficient use.

The absence of an onboard electrical controlled solenoid on the Kiss Explorer rebreather is compensated with a PPO2 display and a connected dive computer which is connected to the oxygen sensor.

For every closed circuit rebreather, the automatic diluent valve is a cogent part. This is because it allows the injection of the requisite gas into the breathing machine do that scuba divers can have breathable gas. In the Explorer, the ADV employs the simplicity of that mimics the functionality of a second stage regulator giving it more efficiency in delivery.

For it mouthpiece, the Explorer has a bailout valve which is designed with two main parts: the dive surface valve and a second stage regulator. These are built into the mouthpiece so that you can have the best of breathing in an open circuit. For more robust ease of use and dexterity, the Explorer’s mouthpiece is designed to exit the breathing loop while switching to open circuit at the same time. This dual functionality is carried out by the simple twist of a knob.
