There are two models of the Hammerhead CCR
Compact design, pre Scrubber O2 Injection, quick bayonet mount, quick disconnect cylinder mounts, 3 Primary O2 sensor cells, primary, secondary, DIVA options and a 4th O2 sensor cell with additional eCCR monitor output as standard. Ultra reliable JMI ADV and Manual Add Valves, 3 Canister, 2 Scrubber and 5 lung options make this a very user adaptable unit. The JM Hammerhead CCR is one of the most advanced closed circuit mixed gas rebreather in the commercial rebreathing market. Innovative, functional and effective, it is a good choice for a technical diver’s eCCR.
If the Hammerhead Classic is ‘The Best’, the Hammerhead Extreme is better. With updated designs to improve functionality and operation, the JM Hammerhead Extreme CCR expands the rock solid design of the Classic.
Both models can be internal configured for just about any combination of controllers on the market. The standard HH configuration is with a primary controller: monitoring cells 1-3 and firing the solenoid, a secondary controller for redundant monitoring of cells 1 through 3 and powering the DIVA. An (Optional) Tertiary controller: monitoring Cell 4.
The IART unit-specific user course, combined with the unit specific IART manual, will prepare you with the knowledge and skills needed to safely dive the HAMMERHEAD CCR within no-decompression limits to a maximum depth of 40m.
- Includes review of nitrox theory, physics and physiology
- Familiarisation with all rebreather components
- Dive planning and execution and emergency procedures
- A written exam concludes the theoretical development.
- Unit preparation, pre-dive checks
- Disassembly, cleaning and disinfection
- Dive planning
- Dive techniques in confined water followed by open water environments
- Protocol in emergency situations
Closed Circuit Rebreather Diver Level I (CCR I). No decompression dives. Air diluent
- Course objectives:
This course develops in the participant, the required abilities, knowledge and techniques to dive responsibly with the closed circuit Hammerhead rebreather within sport diving and no-decompression limits. After successful completion of the course the participant is granted the permission to dive with and purchase the Hammerhead CCR.
50 logged dives, IART Advanced Nitrox Diver certification or Advanced Open Water plus Nitrox Diver equivalent and a valid diving medical.
- Course content/duration:
All theoretical und practical aspects of diving with the JM Hammerhead CCR as described in the IART-manual. In addition to time spent by the participant reading through the manual, the course duration is generally four-five days. It covers, in addition to extending and deepening the theoretical knowledge of the participant, training in pool/CW and open water with not less than 300 minutes in-water time on the Hammerhead CCR.
The instructor : student ratio is not permitted to exceed 1:2.
- Training aides:
IART Hammerhead CCR manual Level I, air/nitrox dive tables, NOAA exposure tables, flash-cards, personal instructor materials.
- Mandatory equipment:
Well-maintained Hammerhead CCR, complete diving equipment suitable to the environment, bail-out cylinder und regulator with min. 600 litres supply, slate and pencil, depth gauge and timer or dive computer.
max depth Pool/confined water: 5m.
OW dive 1: max. 10m,
OW dives 2 + 3: min. 10m – max 20m,
OW dives 4 + 5: min. 15m – max. 30m.
Nodecompression CCR dives planned to remain within limits of O/C nitrox tables.
- Dive skills:
all skills contained in the IART CCR Level I manual must be taught and performed according to the required standards.
- Requirements for certification:
Following completion of the theory lessons a written test must be passed. After successful demonstration of all required practical diving skills the certification is documented by the issue of a certificate and a positive identification card (PIC). In accordance with IART quality control, both the participant and instructor must sign the appropriate training protocol. The Instructor must retain this protocol with the student’s other training documents.
