The Megalodon Rebreather is a compact, electronics-driven fully closed circuit constant PO2 design rebreather (eCCR) manufactured in the U.S. by Innerspace Systems Corporation. The Megalodon is noted for it's highly modular and exceptionally durable construction. ISC resources ensure start to finish manufacturing consistency, making them an ISO 9001:2000 Registered Company.

The ISC Megalodon rebreather is available in several configurations of supply cylinders and buoyancy control systems. For buoyancy control the Megalodon can utilize the Dive Rite systems, or any backplate, harness and wing. Less cylinders, the entire unit can be carry-on luggage for most airlines.

Megalodon Product Features

Breathing Loop
The scrubber canister design contains a water trap, provides simple and quick replacement of the CO2 absorbent and allows easy access to the three oxygen sensors and the battery housings. The dual over-the-shoulder counterlungs are independently shoulder/front-mounted and position adjustable to provide the most effective breathing configuration for your body. Each counterlung contains a water trap and is fitted with a swivel valve for manual addition of your gases and the valve accepts standard BC-type quick release hose fittings. The exhalation counterlung includes an OPV with a spin-valve, providing for the easy removal of any trapped water, even while underwater. The low-maintenance mouthpiece, called the Dive/Surface Valve (DSV), is compact and uses a friction seal so there are no o-rings to wear out and replace. The DSV is designed for easy one-handed open/close operation. Also included is the Auto Diluent Valve (ADV) which automatically adds diluent into the breathing loop during descent as the gas in the loop compresses.

APECS™ 2.7 Electronics Package
The Advanced Personal Environmental Controller System (APECS™) has a simple intuitive menu system and essential information dive screen that minimizes the task loading of the diver. The electronic CCR control system utilizes a electrically isolated and independently powered controller and display handset. The only shared components are the three oxygen sensors which are accessed individually by the handsets, thus requiring independent oxygen calibration on each handset.

  • Primary - The controller is responsible for maintaining the chosen PO2 set-point by firing the oxygen injection solenoid using voting logic with the three oxygen sensors. The primary handset display, normally worn on the wrist, shows the three individual oxygen sensor values plus the average PO2, ambient and breathing loop temperatures.
  • Heads-Up-Display (HUD) - The HUD displays the actual loop PO2 for each of three sensors via a code of flashing red/green LED lights. The LED's also have a user adjustable dim/bright setting.
  • Bilinear calibration - The two-point calibration system provides exceptionally accurate high and low point PO2 information. Calibration can be performed with air and any known gas of 70% or greater oxygen content, and can also be performed at high altitude. Individual sensor MV readings are also displayed on the handsets.
  • Power Management - APECS uses the very power efficient Jaksa automatic oxygen addition solenoid. The handset back light settings are: timed on, always on, and off. Additionally, there is a display power save option, to turn off displays after 10 minutes of inactivity. With these options the diver has great flexibility in managing power consumption and handset readability. The handsets also display the battery voltage, both for no-load and load (i.e. when the solenoid fires), as well as battery low indicators.
  • Set points - The diver has the following set points that may be selected during the dive, or preselected prior to diving: Manual (0.2), 0.4, 0.7, 1.0, 1.1, 1.2, 1.3, 1.4, and Auto Set Point (ASP).
  • Adaptive O2 Injection Algorithm - The O2 injection algorithm which controls the solenoid firing may be adjusted by the diver to select personal preferences to provide very smooth setpoint maintenance.
  • These features are just the highlights, for more details consult the APECS Operational Instructions (v. 2.5).

Petrel Electronics Package
The Petrel electronics package from Shearwater Research provides an electrically isolated and independently powered secondary PO2 display handset. The Petrel is completely OEM integrated with the Megalodon rebreather and provides full real time decompression dive computer capabilities, including required stop obligations and time-to-surface calculation. Features of the new Petrel CCR dive computer include: Megalodon Rebreather Hose Configuration

  • Loop PO2 Monitoring w/CNS Tracking
  • Air, Nitrox, Trimix and Heliox gas support
  • User Defined Gradient Factors Conservatism
  • Easy to Read and Simple to Use
  • Adaptive Menus with Large Display
  • Automatic Setpoint Switching
  • Ascent Rate Display
  • Battery Voltage Display w/Battery Low Warning
  • Metric (Meters) and Imperial (Feet) Units
  • Ultra-Bright OLED color display

Regulator and SPGs
The Megalodon rebreather uses the highly reliable and easily serviceable APEKS first stage regulator. The two regulators each have an Over Pressure Valve installed in a low pressure port. Each regulator has a compact { 1.5 in | 3.8 cm } submersible pressure gauge (SPG), and the Oxygen SPG has a color coded green boot. The oxygen regulator supplies a manual addition valve and the oxygen injection solenoid. The diluent regulator supplies a manual addition valve, ADV, and BC inflator hose. All hoses, gauges, fittings and valves are US industry standard although SPGs are optionally available in BAR.

Cylinder Options
The Megalodon design allows the diver to choose between a large variety of gas supply cylinders using standard left and right modular DIN valves. Divers of varying statures will appreciate this flexibility as they can customize their Meg to fit their body type as well as adjust the weight of the unit by selecting cylinders that are lighter or heavier. We suggest aluminum 19 cubic foot capacity cylinders, which minimizes the rebreather total weight. Drysuit divers might consider steel 23 cubic foot cylinders if they need to provide additional weight. With the volume of the larger cylinders, diluent capacity is sufficient to support on-board bailout for the sport diver, and provides plenty of oxygen capacity even with transfer under filling.

ISC Megalodon Rebreather Harness and Air cell Options
The Megalodon rebreather provides standard { 11 in | 27.9 cm } center mounting which accepts any standard backplate and wing buoyancy control system. Many divers prefer the ISC travel backplate and continous webbing harness with a Tetradon Wing. The Tetradon wing provides better horizontal trim by adding more lift at the bottom end of the CCR and is rated at { 50 lb | 22.7 kg } lift. The wing does not interfere with access to the cylinder valves and also provides a side mount anchor point for side mount systems.

Consumables
The recommended consumables are: Megalodon 7.5V Alkaline Battery Pack, Molecular Products Sofnolime 8-12 mesh (1-2.5 mm granules) CO2 absorbent, DuPont RelyOn MDC (formerly Virkon) 1% solution for breathing loop disinfection, Aerospace Lubricants Tribolube 71 oxygen compatible lubricant for O-ring seals, and Caig Labs DeoxIT GOLD for cleaning gold electrical contacts.

An eCCR Alternative: The COPIS Megalodon mCCR

The Constant Oxygen Pressure Injection System (COPIS II) Megalodon is a closed-circuit manually operated rebreather (mCCR). The COPIS-Meg design includes a special constant-pressure first stage that continuously streams oxygen into the breathing loop at slightly less than the divers oxygen consumption rate. The diver is responsible for monitoring the breathing loop via oxygen sensors and occasionally operating the manual addition valves to maintain the desired PO2 setpoint. The lower cost COPIS-Meg is popular with CCR divers that prefer electronic simplicity but also want the quality and capabilities of the Meg eCCR.

COPIS/Petrel RBX Package - Standard canister with { 5.5 lb | 2.5 kg } granular absorbent axial scrubber, ballistic counterlungs with manual gas addition (MGB) swivel valves and OPV spin-valve, breathing loop assembly with DSV, automatic-addition diluent valve (ADV) with inline cutoff valve (DIV), COPIS 2.7 primary electronics head with HUD, O2 hose with flow restrict and filter, setup flow meter, Petrel secondary electronics, single tank adapter, crotch strap, low-pressure hoses, compact SPGs with high-pressure hoses, first stage regulators, Shadow Mount cylinder mounting system, accessory package including dust caps, decals, hat. (Does NOT include the backplate, harness, wing, cylinders and valves which may be ordered separately.)

COPIS/Petrel RBX Stripped - Same as the COPIS/Petrel RBX Package, but does not include cylinder mounting system, first stage regulators, SPGs, and high-pressure hoses.

COPIS RBX Package - Same as the COPIS/Petrel RBX Package, but deletes the Petrel secondary electronics.

Rebreather Training

Every rebreather requires formal, model specfic, training in order to competently dive with the equipment. Our pricing does not include training, and training is solely the responsibility of the purchaser. Training is available worldwide and Dive Gear Express also offers instruction at our facility in SE Florida for all models we sell. The typical full course training time is five to seven days consisting of a classroom lecture, confined water session and at least six OW dives. Our recommendation to divers seeking rebreather training is to select an instructor having several hundred hours of rebreather dives and for whom rebreathers are their primary mode of diving.

Because diving is a voluntary recreational activity, prior to delivery and training you must complete and sign legally binding agreements known as a Release of Liability and an Express Assumption of Risk. If you are not already certified for the rebreather, per manufacturer requirements you will receive a disabled unit that can only be enabled by your instructor. Once you complete training, your instructor will permanently enable your unit.
