That does look nice, though I question the 425ft
depth. If it requires the cap being closed then it's bound to fail that
depth rating petty quickly as the
gasket looses it's perfection. After you've owned it for a year i bet its good to about 100ft at best. That's a LOT of pressure.
But honestly, if you are down 425ft, it's too late to use it. Might be good for divers in strong currents though.
