When in use, a scuba diver can easily integrate the Megalodon with several other types of electronic systems for more effective functionality.

The Megalodon comes in 21 versions to provide maximum support to customer needs.

It is well fitted for use as a side mounted system for penetration into extreme enclosed spaces and can also be tweaked to double as a twin system for CCR redundancy in extreme deep diving operations. This is highly practicable for instances where carrying open circuit bailout is largely impractical. The ISC Megalodon CCR or more fondly called “The Meg” is a closed circuit rebreather system that has been loved and used by scuba divers of all skill levels the world over.

Divers who use the Megalodon can safely dive from 60fsw to over 742fsw / 225msw. Crafted with high-end versatility in mind, it can be configured to meet any level of diving and keep pace with the skill levels and experience of any diver type – recreational, professional, military, etc.

Megalodon CCR Review

From the design stage, the Megalodon was crafted to efficiently work for highly demanding dives with much consideration for any dive type and any divers’ breathing needs. Addressing not only the necessary requirements of performance that a true 3rd party tested CCR must undergo but also the other factors that are not considered, such as travel concerns and conducting repairs in remote locations.

For further assurance of efficiency and unparalleled delivery, the Meg is built with two independent handsets which have independent batteries packs for more elongated power time. If a diver chooses to, they can upgrade one of the handsets to a Shearwater Petrel based on preference and still have the best bespoke breathing experience that is reserved for every Megalodon user.
