"The 'Meg' Rebreather is all class. Quite simply it is the class leader when it comes to reliablity, quality and versatility. You will keep noticing the quality long after you have forgotten the price.
Overview of ISC Megalodon Rebreather
  • Ultimate in CCRs (closed-circuit rebreathers)
  • Modular rebreather "head", with two options:
    • APECS2 electronic solenoid-based O2 injection system
    • COPIS manual constant-flow O2 injection system
  • Two options for canister length:
    • Standard can, with 2.5 kg (5.5 lb) scrubber
    • Mini-Meg can, with 1.4 kg (3 lb) scrubber
    • Even more scrubber options being released soon
  • Very robust construction, with milled copolymer acetal and mil-spec anodized aluminum.
  • Over-the-shoulder counterlungs and a carefully designed loop offer exceptionally low work of breathing in all positions
    • Cordura Nylon standard, simple and durable
    • Neoprene, for lower overall profile
  • Three Teledyne R-22D oxygen sensors
  • Water traps and T-Piece baffles in the loop make the unit very resistant to flooding and flood recoverable
  • Any standard 2-bolt backplate, wing, and harness may be used
  • Dived to over 200 meters (660 feet)
  • Travels easily: the entire system, minus cylinders, can be packed into a hard case that will fit in an airline overhead bin
  • Choice of Tanks. Just about any tanks can be used. Great for travel as one can use whatever tanks are available

The Megalodon is an expedition level closed circuit mixed gas rebreather, with the versatility, modularity, and robustness for any range of dives, from shallow tropical reef dives to the most extreme deep cave and wreck exploration. The Meg is an exceptional entry-level rebreather, and has also proven to be faultless on dives to over 200 meters.

The Meg offers two different options for control systems, one making it a manually controlled rebreather (mCCR), the other making it electronically controlled (eCCR). The two heads are interchangeable, so one may be purchased initially, and then kept as a backup when upgrading to the other.

The mCCR option is the COPIS (Constant Oxygen Pressure Injection System) head, which uses a constant-flow orifice that injects oxygen at slightly below the diver's metabolic rate, making manual control of PO2 simple and easy. The system includes a handset display with large numbers for each of 3 oxygen sensor readouts.

The eCCR option is the APECS2 head, which uses a solenoid to electronically maintain the PO2 at a desired setpoint. Two redundant computers, each with an independent power supply and handset display, provide PO2 readouts. A heads-up LED display provides a constant PO2 display without the need to look at the handset.

The Meg is all about choice; the diver may use their choice of tanks, regulators, wing, backplate, or counterlungs, or order their unit as a turn key solution. There are even two different choices for the main canister size. The whole system is very modular and reconfigurable, making it easy to travel with and adapt to the diver's specific needs. Do you want a light sporty unit or a hard core expedition grade work horse?
