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 O2ptima is a fully closed circuit, constant PO2, electronically-driven rebreather with built-in decompression ability. Unique in the rebreather marketplace, the O2ptima is specifically designed for the rigors of cave diving where immediate surfacing is not possible. The resulting features are also highly desirable for wreck and deep ocean divers. The O2ptima's design includes minimal risk of a caustic cocktail. Two water traps in the loop along with horizontal, behind-the-head positioning of the scrubber canister create a difficult path for water to travel. An even greater advantage is gained by using Micropore Extend Air scrubber cartridges, which do not contain dust. It is the dust that reacts quickly with water to form a caustic cocktail. The O2ptima delivers excellent work-of-breathing that allows divers faced with strong flow or ripping current to breathe comfortably. Over-the-shoulder counterlungs along with the scrubber positioned behind the head means gas has less distance to travel, so the diver does not have to work as hard to "pull" gas through the loop. This also allows the O2ptima to have smaller diameter loop hoses, which minimizes jaw fatigue. A stainless steel frame and Rhinotec 600-denier polyester cover protects the O2ptima from tight cave squeezes and rolling boats. Hoses, regulators and tanks are kept neatly streamlined and away from potential snags inside a wreck or cave.   The O2ptima comes standard with the following features (see tech specs for details):   Over-the-shoulder counterlungs Shearwater Divecan - Petrel controller Shearwater Divecan Heads Up Display (HUD) Dive Surface Valve (DSV) Automatic Diluent Valve (ADV) Water traps XT Regulators and hoses AI R22 Oxygen Sensors Choice of Dive Rite harness CCR XT wing   Tech Specs:   COUNTERLUNGS: Over-the-shoulder 2.5L counterlungs, 5 liter total loop volume provide easier work of breathing in all dive positions. Counterlungs include diluent and oxygen manual addition valves. An over pressurization drain valve is located on the exhalation counterlung. The O2ptima counterlungs are covered in tear-resistant Rhinotec. ( 6 liter set available on request) ELECTRONICS: Powered by Shearwater Research, using the latest in Shearwater technology the DiveCan system. The oxygen injection has an independent control board and long lasting 9 volt battery with a detachable Petrel controller. BACK UP ELECTRONICS: Powered by Shearwater Research, using the DiveCan Heads Up Display (HUD). This unit has its own control board and long lasting 1.5 volt power supply, all contained in its own seperate housing. The HUD has seperate LED's for each oxygen cell, color blind mode and red buddy warning light. OXYGEN SENSOR MONITORING: The system utilizes 4 oxygen sensors, sensors 1 & 2 are shered by the Primary and Backup systems while the third cell on each are independent for maximum redundancy. DSV: Dive surface valve utilizes a friction seal so there are no o-rings to wear out and replace on the barrel. ADV: Automatic diluent valve adds diluent to loop automatically maintaining a breathable volume. Located on the inhalation counterlung, the ADV includes an in-line shutoff in case of free flow.

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. Package includes:  Scrubber head complete with all required parts, including ADV, exhaust valve, hose attachment tower’s, & canister Counterlung case with detachable manifold, tank rails, back plate attachment bolts, & 4 cam straps Two counterlung’s (2&4 liter is standard; other configurations are available upon re‐ quest) Two 22 inch loop hoses Two hose stubs with lined hose clamps (loop hoses to scrubber tower’s on head) Oxygen Manual Add Valve (MAV) and filter, with two flexible oxygen rated hoses O‐rings (two complete sets) Spare counterlung ring Cam strap system for securing cylinders Delrin plug for oxygen side 1st stage regulator (see list of approved model first stages) LP diluent hose with hose adapter (ADV swivel to manifold) Oxygen & diluent first stage’s, HOLLIS mouthpiece with hose aƩachment’s, 3 K‐22D oxygen sensors, & the sensor plate with hardwired Shearwater PPO2 display Classic Explorer mCCR Specifications Depth Rating: 300 fsw / 91mswScrubber Type: Axial designScrubber Capacity: 5.7 lbs. - Molecular 797 Grade (812 Mesh) Sofnolime.Max Counterlung Capacity: 8 Liters (2 x 4 liter lungs)Dimensions: 21”H x 14”W x 8”D (54cm x 36cm 20cm)Weight: (w/full 13 cu.ft. aluminum cylinders, packed scrubber - no BCD, back plate or harness) 51 lbs./ 22 kg.
