InnerSpace Systems Corp™ Megalodon® Closed Circuit Rebreather The basic core system of the Megaldon is comprised of the outer housing, scrubber assembly, head assembly including oxygen sensors, control electronics, handset or handsets and HUD (Head Up Display). The latest model features Shearwater electronics which are a combination of single handset, HUD and onboard Nitrox and Trimix computer with selectable gradient factors. Shown throughout this article are the optional mark meadows backplate, ADV, flow stop and Tiger Gear bottle mounts that allow any supply bottle to be mounted to the canister. Other bottle mount systems such as the metalsub brackets can also be used but are not as robust as the Tiger Gear mounts. |

| Movie
Meg, Back View Notice the two cambands, which attach the scrubber canister to the backplate shown in the next image below. This plate was designed with help from Mark Meadows, and provides the absolute lowest profile possible. This particular canister is identical to the units ISC custom built for use in an upcoming movie. The canister was developed with the help of the fine folks at Micropore, specifically to use the Extendair® "solid state" scrubber cartridges, but can be used with the standard Meg scrubber without the internal canister spacer. This canister is called the Movie Meg and is shorter than the standard Meg canister but longer than a Mini Meg canister. |

| Low Profile
Backplate Low profile Mark Meadows backplate. This backplate is viewed here on a aluminium 12 Litre scuba cylinder. Constructed of 316L stainless steel, it weighs less than 2 pounds. The backplate was used in the unit shown above. |

| Size Comparison From Left to Right. Movie Meg, a aluminium 12 Litre scuba cylinder and the standard Meg scrubber housing, anodised silver. There is a variety of colours available for the anodised canisters. |
 |
||
| Traveling Here the Movie Meg is packed into a Pelican case that will fit the carry on restrictions. For travel, you can simply rent whatever bottles are available at your destination. |

| Meg Head, Top This first image shows the solenoid, O2 feed post and support, the solid potted computer box, both handsets and the heads up display. |
 |
||
| Meg Head, Bottom This is the bottom view showing the battery boxes, sensor carriage retaining plate, handsets and HUD. The head, handle, battery boxes, sensor carriage, solenoid mount, handset housings, buttons and button guards are all machined in house from solid blocks of copolymer acetal. The handset cover is machined from Lexan plate. Also visible is the ISC manufactured stainless steel solenoid base. The newer Megs feature a brass solenoid base. |

| Meg Head, Sensor Carriage In this view the interior of the sensor carriage is revealed, exposing the O2 sensors and the absorbent material for collecting condensation, lung-butter, etc. |
 |
||
| Brain Box This box contains and protects the electronic control and display circuitry. The circuitry is cast solidly into an 80 durometer potting compound that is tough as a hockey puck. Also shown are the three Teledyne R22D O2 sensors, with an optional AI sensor, and a BioMarine sensor out of an older MK15.5. |
 |
||
| Battery Box This box is made of milled acetal for ruggedness and is o-ring sealed to eliminate the issues of off gassing into the breathing loop or salt water intrusion into the battery cavity. The Meg uses two entirely separate computers, power supplies and displays for true redundancy. It is operated by a magnetic switch. |
