Fathom Gemini CCR
The FATHOM Gemini is split-scrubber design mCCR. While similar in design to other units on the market, the Gemini is constructed with the finest components and designed with exploration in mind.
Specifications
• 5” (127 mm) dia x 13” (330 mm) tall
• 20.2 lb (9.2 kg) without cylinders or scrubber material
Heads
• No batteries inside head eliminates the possibility of toxic chemicals in breathing loop
• Fully potted and submersible head eliminates the possibility of corrosion on sensitive life‑support equipment
• Splitter/isolation board allows two devices to monitor oxygen sensors
• Hardwired leads and coaxial SMB connectors on oxygen sensors eliminate multiple connections and fragile Molex connectors
• Minimal head space reduces static loop volume
• Gas addition in exhale head insures proper gas mixing in scrubber before it reaches sensors and diver
Breathing Loop
• Backmounted counterlung provides excellent work of breathing (WOB) in all positions while keeping frontal area free of clutter for stage bottle mounting and minimizing diver’s profile
• OPV in counterlung acts as a water dump and allows diver to dewater unit if needed
• Shrimp DSV with quick disconnect bayonets allow for easy cleaning and inspection of one-way valves
• Optional Shrimp BOV allows for rapid bailout without removing mouthpiece
Scrubber
• 4.8 lb (2.2 kg) dual axial scrubbers
• Removable and swappable scrubber baskets
• Black Amalgon canister insulates scrubber 400 times better than aluminum
• Latchless head, canister and bottom streamlines profile
Dual MAV/Needle Valve
• Needle valve incorporates the simplicity of a constant mass flow (CMF) orifice without the IP adjustment issues or the risk of blockage from debris
• 316 SS Swagelok needle valve for precise flow
• Fully recessed manual oxygen addition button prevents unwanted oxygen addition
• Non depth compensated Apeks DS4 1st stage with stronger spring allows for adjustment from 200-290 psi (14-20 bar) IP for 400-600 fsw (122-183 msw) maximum depth
• Fully recessed manual diluent addition button prevents unwanted gas addition
• Female QC-6 plugs into offboard bailout/diluent
• Bypass port routes gas directly to optional BOV
PO2 Monitoring
• NEW and improved HUD provides reliable secondary PO2 monitor
• Reversible display
• Automatic brightness adjustment
• Voltage indication on start-up
• Visual alarm feature
• NEW Shearwater Petrel 3 primary display
• Optional Shearwater NERD 2 replaces Petrel 3 as primary display

We are able to teach you from the very beginning of rebreather diving, all the way through CCR Hypoxic Trimix. Please see our other course offerings for advanced CCR training.
Certification is through IANTD.
- If you lack prior CCR experience, there is a five-day program that will take you all the way through to full CCR Diver certification.
- If you are already certified on another CCR, there is a two-day crossover program that will make you a fully-certified Gemini CCR Diver.
If you have no prior CCR experience:
- Be at least 18 years old
- Have at least 50 logged dives
- Be certified to the Advanced Nitrox/Deco Procedures Diver level or equivalent
If crossing over from another CCR certification:
- Have logged at least twelve CCR dives
- Have made at least one CCR dive in the past 45 days
- The “from scratch” CCR course takes five days and at least 400 minutes of bottom time.
- The crossover course takes two days and at least 200 minutes of bottom time.
- With sufficient notice, we can usually accommodate requests for specific course dates.
