The Megalodon CCR Rebreather is delivered in two versions, either a computer controlled Closed Circuit Rebreather (e-CCR) or a mechanicaly or manually controlled Closed Circuit Rebreather (m-CCR) with a 2.5 kilo Carbon Dioxide (Co2) axial absorbent canister that filters the Co2 out of the breathing gas circulating inside the breathing loop.
In the electronic controlled APECS version an onboard computer controls and changes the oxygen partial pressure (Po2) in the breathing gas circulating inside the breathing loop to the demand and input of the diver. In the mechanic or manual controlled COPIS version the diver is reading the Po2 in the loop via a Po2 readout and injects manually the oxygen needed to maintain the desired Po2 into the Rebreather.
The Megalodon CCR can be used as a nitrox unit, normoxic trimix unit and is trimix capable to a depth of more than 500 feet / 150 meters. The CCR Megalodon Rebreather is currently used for a wide range of diving applications such as recreational diving, cave diving, wreck diving or technical diving.
The Megalodon CCR Rebreather is an extremely wel made CCR, sporting double heavy-duty o-ring seals on all connections, a heavy-duty aluminum stack where the electronics and CO2 absorbent canister is living in. The unit comes without a harness system so individualism is the motto of the day when it comes to how to wear the unit. Options range from Transpack soft packs to slim or full size stainless steel, aluminum or ABS backplates or even Armadillo sidemount systems. The Automatic Diluent Valve ( ADV ) is a nice safety feature addition during busy events or runaway descents. The Heads Up Display ( HUD ) is an easy to read display feature enabling the diver to watch the Po2 at all times, even the busiest ones.
The Megalodon CCR is an electronically controlled rebreather with three oxygen sensors but it can be also be used manually with dilluent and oxygen inflators mounted on the counterlungs. The COPIS Megalodon is a manual controlled CCR, not having any electronics that electronicaly inject oxygen into the unit but still featuring the three oxygen sensors.
The APECS e-CCR has two hand sets, the electronics are easy to use menu with an excellent feature being the ability to show readings to see when the sensors expire or for oxygen calibration. Another great display is of the batteries voltage to see when they are ready for a new set. The COPIS m-CCR has only one hand set.
For those seeking a reliable, extremely well made and durable closed circuit rebreather, the Megalodon CCR must feature high on the demand list.
