Comments about Aqualung AquaLung Kronos Supreme Regulator with Free Calypso/Titan Octopus:
Did not have any problems out of any of this. Best part is the ACD which closes off your 1st stage to prevent rust etc. Most people forget to put the valve back on after their dive when rinsing them, however, this one closes automatically for you so you don't have to worry about it. Very comfortable and eash to use. Turned out great for pictures!
