Howdy to all, I have been monitoring my SAC and for the time being, a 12 liter tank goes from 200 bar to 70 bar in about 43-45 minutes at a depth of 11 meters to 12 meters, it is not wonderful, and I do have a lot to improve on my breath rate now that I'm approaching 24 dives, have 22 at the moment.
The thing is, I need to improve my longevity under water to accompany most of my buddies at those sorties that I've been doing, and I'm tempted to do an investment on a bigger tank, I've been seeing some huge ones, from 15 liters to 18 liters to even a mammoth 20 liter tank, I'm an heavy guy and I admit, I need to do a lot more exercise to be in shape, so, when I dive, even without a wetsuit I still need 4 kg's of led to at least .. sink, so my idea, and forgive me if it sounds silly "that's why I'm asking in the first place" is that if I have an heavy tank on my back I can avoid bringing led on my bcd and have more air, I am aware that buoyancy changes as the tank becomes depleted of air, so my idea is to invest in steel tanks.
I never tried something bigger than a 203 mm 12 liter tank "the fat one" so I ask for your knowledge, is a 18 liter or 20 liter to overwhelming to the balance of a diver? I am about 6 feet, does a tank as large as that one become to cumbersome to be of a efficient use?
Thank you for your atention!
