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.
