Will I be able to freedive or scuba with this on (without damaging it?

Yes, you can go diving with Restube. However, you must keep the following in mind: When you descend, the ambient pressure increases by one bar for every 10 m of water depth; at the same time, the buoyancy force at depth is reduced because the gas is compressed. This results in the following buoyancy depending on the depth: 0m depth = 1 bar = full buoyancy = 75N = 7.5kg 10m depth = 2 bar = half buoyancy = 37.5N = 3.75kg 20m depth = 3 bar = third buoyancy = 25N = 2.5kg 30m depth = 4 bar = quarter buoyancy = 18,75N = 1,87 kg 40m depth = 5 bar = fifth buoyancy = 15N = 1,5 kg As you get higher again, the resulting buoyancy of the buoy increases until it is fully available again at 0m. The deeper you dive, the lower the buoyancy. Feel free to let me know if you have any further questions. Best regards, Philipp /for RESTUBE

Is a CO2 cartridge pre-installed or sold separately?

There is one cartridge coming with the Restube. But it comes separately. You need to screw it in - but it's very easy. Please find attached the instruction video (starting at 0:50). It takes only one minute to make Restube ready to use. Let me know if you have any questions. Best regards, Philipp /for Restube

No, Restube is not certified as a personal floating device. At the moment, there is no category where Restube fits in to be certified as a pfd (there is no category for a belt with an attached floating buoy). Best regards, Philipp /for RESTUBE
