I’m thoroughly impressed with the Fusion Octopus! The VAD technology has completely changed my diving experience. It’s so much easier to breathe, even in cold water, and I feel more at ease during long dives. The design is sleek and compact, making it easy to carry around. I would definitely recommend it to any diver looking to upgrade their equipment.

What is the recommended maintenance schedule for the Fusion Octopus to ensure optimal performance?
Imran Hanafiah –
Thank you for choosing the Mares Fusion Octopus. For optimal performance, we recommend cleaning the octopus after each dive and storing it in a dry place. It’s also essential to check the rubber facings for signs of wear and tear and replace them when necessary. As for specific maintenance, we recommend inspecting the valves and seals every 10 to 15 dives and replacing them if you notice any leaks or corrosion.

Will the Fusion Octopus work well with integrated wetsuits in cold water conditions?
Imran Hanafiah –
Dear Eugene, thank you for your question about our Mares Fusion Octopus. We’ve had numerous customers successfully use their Fusion Octopus with integrated wetsuits in cold water conditions, and the Twin Power System has withstood the stresses of these situations. However, we recommend ensuring the Octopus is properly maintained and seasoned with a cleaning solution before using it in cold water to get the best out of your gear.

I’ve been using the Fusion Octopus for a few months now and I must say it’s been a great addition to my diving equipment. The Twin Power System really makes a difference in terms of breathing effort and I feel more comfortable during long dives. However, I did experience some minor issues with the VAD mechanism getting stuck after a particularly intense dive. Still, I would recommend it to fellow divers.
