This course is designed for certified rebreather divers on another unit who wish to learn how to dive a FATHOM MK III CCR.
The FATHOM Mk III CCR is designed to be the simplest and most intuitive closed-circuit rebreather for underwater exploration. Several years ago, as their dives became increasingly deeper and longer duration, Karst Underwater Research (KUR) divers recognized the need for a new closed-circuit rebreather (CCR) with excellent work-of-breathing and long scrubber duration that would stand up to the rigors of cave exploration. The short list of desired features included:
a radial scrubber for the best possible work-of-breathing and scrubber efficiency,
at least an 8 lb/3.6 kg scrubber capacity for long duration dives,
back-mounted counter-lungs to maintain streamlining and easy stage-bottle handling,
off-board gas addition capability for diluent/bailout, and
mechanical oxygen addition for reliability.
Unable to find an existing unit that met these requirements, KUR diver Charlie Roberson started to design what would eventually become the FATHOM CCR. There are no easy decisions when it comes to rebreather design and every choice, every dimension, every o-ring, was debated endlessly with fellow KUR divers. Ultimately, the final decisions were Charlie’s and his background as a machinist in the US Navy and Hogarthian/DIR cave diver guided him towards simplicity and functionality. The result of these efforts was the FATHOM CCR. Refinements to the original design continue and the FATHOM Mk III CCR is the latest version.
As with any diving equipment, it is essential to receive proper training and certification before using the FATHOM MK III or any rebreather system. Diving with a rebreather requires additional knowledge and skills beyond open-circuit scuba diving due to the different gas management and potential risks associated with closed-circuit systems.
IANTD CCR ADV. RECREATIONAL TRIMIX (PLUS) FATHOM MK III DIVER
$2,000.00
This is the second level certification course for divers wishing to utilize a Closed-Circuit Rebreather (CCR) for mixed gas diving using a Helitrox Diluent. You can take this course directly if you are a trained decompression diver in open circuit. The objective of the course is to train divers in the benefits, hazards, and proper procedures for diving a CCR and to develop basic CCR diving skills, to a maximum of 45 meters/150 feet, using an air/nitrox/helium diluent for formal decompression diving. Students are permitted to utilize a diluent and bailout mix with no greater than a 35% helium content and no less than a 20% oxygen content.

IANTD CCR FATHOM GEMINI DIVER CROSSOVER
$1,200.00
This course is designed for certified rebreather divers on another unit who wish to learn how to dive a FATHOM Gemini CCR.
The FATHOM Gemini is a split-scrubber design mCCR that goes on a standard open circuit sidemount setup. It gives you an extremely streamlined and flat profile, which makes it an excellent tool for cave diving. You don’t need to change your style of diving if you are an avid sidemount diver already. FATHOM Gemini features the same needle valve for oxygen addition, in this case, on a dual-button MAV. It comes standard with a GOLEM DSV, but can be easily switched to a GOLEM BOV, if preferred.
