Megalodon
General Description: The Megalodon CCR Rebreather is a fine piece of diving machine 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 is coming without a harness system so individualism is the motto of the day when it comes how to carry the unit ranging 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 a sweet dream to dive with enabling the diver to watch the Po2 at all times, even the busiest ones.
Type of Rebreather: CCR electronically controlled with three oxygen sensors but can 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.
Number of handsets: Two hand sets for the APECS e-CCR, electronics easy to use menu with excellent milivolt ( mV ) readings to see when the sensors expire or for oxygen calibration. Great display of batteries voltage to see when they are ready for a new set. One hand set for the COPIS m-CCR.
Location of main electronics: In the original unit the main electronics are located in the lid right next to the sensors, solenoid and battery compartments. Older units have the electronics podded while newer units have a electronics housing allowing the individual circuit boards to be replace dshould the need arise, instead of changing the whole electronics section.
Information displayed in the handsets: No decompression information, time or depth is displayed at this point in time. The Po2 is displayed on the main default screen. Set points can be chosen ranging from manual to 0.4, 0.7, 1.0, 1.1, 1.2, 1.3 and 1.4.
Heads Up Electronics ( HUD ): Rebreather has optional HUD that is a must have
item, that works great.
Amber blink: Po2 is 1.0
Red blink: Per red blink a Po2 of 0.1 below Po2 of 1.0
Green blink: Per green blink a Po2 of 0.1 above Po2 of 1.0
Sensors: Three Theledyne R22D sensor are used in the original manufacturer version.
Batteries: Battery packs utilizing AA batteries that have to be soldered together into packs of 5 sitting in two independent battery compartments inside the stack and lid together with the main switches. Larger D size Lithium cell packs can be used.
Automatic Dilluent Valve ( ADV ): Optional available with older larger version utilizing a Scubapro second stage and newer streamlined version designed by Innerspace Systems. A must have item.
Diveable weight: Around 75 lbs / 35 kilos with absorbent and depending on what size and material of onboard tanks was chosen.
Travel weight: Unit can be shipped in carry on without tanks, excellent choice for people who travel a lot.
Canister design: Unit can be dived with regular absorbent canister designed to hold 2 ½ kilos absorbent with axial flow. Optional are the Extended Air cartridges from Micropore with two special adapters as well as radial flow cannisters by either ISC or aftermarket suppliers.
Canister duration: Axial flox canister around 4 1/2 hours with 797 grade Sofnolime or Sodasorb in warm water. Around 3 hours in cold water. With grade 408 Sofnolime or Sodasorb around 3 hours duration in warm water. With the radial flow cannister 6 to 9 hours with 797 grade absorbent in warm water can be reached. Radial or Extend Air Cartridges adapters and use optional.
Absorbent recommended: Grade 797 Sofnolime or Sodasorb ( the small stuff ) recommended. Larger grain absorbent can be used. Medical grade absorbent as well as Draegersorb has been used by some divers.
Counterlungs and position: Two over the shoulder counterlungs, used to be made out of neoprene but are now of lined denier material, around 5 ltr. Capacity. The inhalation counterlung on the right side has one oxygen inflator connected to the oxygen tank. The exhalation counterlung on the left has the ADV and the dilluent inflator, both connected to the dilluent tank and the overpressure valve at the bottom of the lung which allows for excellent flood recovery. The gas flow and rotation is counter clock wise. Neopren counterlungs can be bought for cold water diving.
Flood recovery: Good flood recovery due to low overpressure valve in exhalation counterlung. Large water trap in bottom of stack housing, closed and water tight battery compartment as well as electronics.
Support locations worldwide: U.S.A., Canada, Mexico, Europe, Asia, Australia, South America
Special uses of unit: The Megalodon CCR was used for deep diving operations of the Cayman Islands walls, deep cave diving operations in Florida, Asia and the Bahamas as well as deep wreck diving operations in Asia. The underwater scenes of the movie “The Cave” were shot using the Megalodon Rebreather modified with a back shell.
Current delivery time: Around 2-6 weeks.
