Dive Rebreather - Extend Dive Times With the Right Rebreather

Used by United States Marines Combat Divers around the world, Professional Underwater Videography Teams and Scientific Dive Teams, the Kirby Morgan Modular Full-Face Mask represents a giant step-up in safety, versatility and convenience over conventional Full-Face Masks (FFMs). Known simply as the “MOD-1”, the patented Kirby Morgan two-chamber (Mask & POD) design opens up multiple configuration possibilities with both Open Circuit and Closed Circuit Rebreather systems never before available. Hollis is excited to partner with Kirby Morgan Dive Systems, Inc, the designer of commercial and military diving systems, to bring our divers a product, the MOD-1 with optional Hollis BOV Pod, expanding the possibilities in diving safety, reliability and versatility. (Pictured with the optional Hollis BOV Pod.)   The MOD-1 utilizes two separately sealed cavities in a single FFM design. The Mask which acts exactly like an independently sealed dive mask, and a lower Breathing Pod which contains the mouthpiece; which can be used in Pod recovery and gas sharing emergencies, a dewatering one way valve and a hook and catch, release for sealing and releasing the Pod to the Mask. Wireless or hardwired communications can be installed into the Mask and when communicating with other divers underwater or topside, the diver can simply talk normally as the microphone rests nearby the mouth. At the surface, with the Pod removed from the mask, communication is very clear as there is no need to talk through a mask to your buddy or topside support crew. Switching gasses underwater or bailing out to an off-board system in the case of Rebreather use with the Hollis BOV Pod, is simple and straightforward because of the MOD-1's two chamber. The diver simply detaches the lower Breathing Pod and secures either a secondary Open Circuit Pod, or simply a second stage without a Pod attached. The Mask does not flood during this exchange, or when breathing off a second stage with no Pod attached! This dramatically increases safety and versatility over conventional one-piece designs where a bailout means momentarily losing breathing gas and the ability to see underwater. With the Hollis BOV Pod, bailing out to Open Circuit requires only flipping the CC/OC lever to Open Circuit mode. You do not lose critical time, communications or visibility, and you don’t need to grab a bailout mask. Because the MOD-1 utilizes glass lenses instead of plastic, you can install custom-ground prescription lenses, a critical feature for underwater videographers and photographers to get that perfect shot, in perfect focus. For Hollis Prism 2 and Explorer divers, the MOD-1 with Hollis BOV Pod has several important safety considerations, which cannot be understated. First and foremost, should a diver become unresponsive underwater, their airway is protected while a buddy switches the BOV to Open Circuit mode and starts the flow of a “known” gas. Secondly, if added, voice communications between dive teams means rebreather divers can alert team members to a potential issue, have more than one brain available to discuss solutions, and make the critical go/no-go decisions that will insure a safe return to the surface.

The Prism 2 is an electronic Closed Circuit Rebreather providing divers a proven platform to explore the underwater world. The Prism 2 gives divers a New Ocean. Bubble free diving allows the diver to integrate into ocean life – rather than intruding on the underwater realm. The Prism 2 delivers comfortable warm breathing gas in an optimal breathing mix at any depth. This extends no-decompression times; allowing divers to take advantage of the Prism 2’s more efficient gas use. Electronic CCR (Closed Circuit Rebreather) Only commercial CCR to pass unmanned and manned testing by the U.S. Navy Radial scrubber design provides lower resistive breathing effort and more efficient scrubber use Primary HDD (Heads Down Display) is battery driven sequential LED, for continuous hands free monitoring of the oxygen levels. Independent Analog Secondary Display works even if the battery is dead powered by the O2 sensors. O2 supply lines and solenoid are external from the breathing loop. This removes the risk of O2 spikes due to O2 connection leaks. O2 is safely vented into the surrounding water column. Pre-Dive user selectable PO2 Setpoints Standard Diluent and O2 bottle size 19 cuft (2.7 liters) but for greater flexibility the unit can accommodate 13's, 19's; 30's (cuft) / 1.9, 2.7; 4.4 (liters) Electronics and the battery are housed on their own outside of the breathing loop.. Uses a standard 9V alkaline battery which can be found easily worldwide Long battery life of 40 hours in 70F water temperature Convenient purge drains at the base of each counterlung Electronics are sealed and protected from accidental flooding Counterlungs mounted over the shoulder to decrease work of breathing Waterproof magnetic slide on/off switch used for reliability in a salt water environment 3 O2 sensors for redundant and reliable oxygen management Ergonomic Hollis 310 inline alternate inflator used as an onboard diluent bailout  

As the name indicates, the KISS Sidekick is a streamlined, lightweight rebreather system that has been designed specifically for side-mount diving applications. This system was created in response to the needs of cave divers and explorers working in situations where back-mounted rebreather's create a hindrance for negotiating tight restrictions. In these situations, the Sidekick becomes the obvious choice as a stand-alone rebreather. Due to it's compact size and mounting position, it can also be carried as a bailout rebreather (BOB) system. The most striking feature of the Sidekick is its small size. Without the loop hoses, the unit measures 21.25 inches (54 cm) in length by 7.25 inches (18.4 cm) in diameter. This compact profile, combined with the unit's simplicity of design and reliable mechanical operation make it well suited for use as a side mount GEM SCR or CCR rebreather, bailout rebreather or simply as an add on gas extender, with none or very few modifications required to fill all of these roles. Like all KISS systems the Sidekick is a mechanical rebreather, so there are no electronics controlling the gas addition to the system. Its unique design places both the head and scrubber inside a large single counterlung, which in turn is housed within and protected by a cylindrical shaped stainless frame. The Scrubber head is a single chamber that holds three sensors. It is fitted with 2 hose attachment towers for the loop hoses, gas addition fitting(s), ADV and exhaust valve. Due to the nature of the counterlung's configuration around the scrubber, the sidekick’s in-water buoyancy is close to neutral. It becomes slightly positive (varies with diver’s tidal lung capacity) during the diver’s exhalation cycle, then slightly negative during the inhalation cycle. Because the scrubber is surrounded by the same gas coming and going to the diver, the scrubber is able to retain more warmth. This is a benefit as temperature is an important component for the chemical reaction to take place, and the insulation of the counterlung helps maximize CO2 extraction by the absorbent. The scrubber holds 5.2 lbs. / 2.4 kg of Sofnolime 408 grade absorbent (weight can differ between brand absorbents).  Fully assembled and ready to dive, the unit’s weight out of water is 22.2 lbs. / 10.1 kg. Fully assembled but without absorbent, the weight drops to 17 lbs. / 7.7 kgs, making it very suitable for travel.  The scrubber chamber can also accept a large bore, 5-inch diameter Micropore brand cartridges (part number SR-0801C) in place of granular type absorbents. Like the KISS GEM SCR, the GEM Sidekick SCR uses the same patented passive-addition DSV. By shunting a portion of each exhaled breath back into the loop, this device will extend the duration of a given gas supply by a factor of three. The benefits of this type of gas-extension provide advantages for both recreational and technical diving.  Note that proper training outside the level 1 GEM Sidekick course is required prior to doing any technical diving. For some types of diving extra gear must be carried or alternative gear configurations will be required. Ensure that you have the proper training, gas and gear to conduct your planned dive.

Although the primary components are almost exactly the same as those of the KISS GEM Sidekick SCR, the mCCR version features a few differences. In place of the special GEM DSV needed for SCR use, the mCCR version ships with a standard closed-circuit rebreather mouthpiece (DSV). (Note: This is the only CCR model offered by KISS Rebreathers that does not include a BOV.) Other changes include the addition of a MAV (the same used in all KISS CCR’s) for controlling oxygen addition to the loop.  (Note: The low pressure hose feeding the manual oxygen addition system must be secured to a first stage with the KISS delrin plug installed.) To provide reliable, real-time PO2 monitoring, the Sidekick CCR uses the same triple oxygen cell configuration as other KISS CCR models. These cells are wired to a Fischer cable, or as an optional up-grade, can be hardwired to a Shearwater Petrel computer.  This unit is compatible with Trimix.   Dimensions: 21.25 inches (54 cm) long by 7.25 inches (18.4 cm) in diameter.
