Personal submersibles are becoming the latest must-have toy for the billionaire boat owner who already has it all. Just owning Jet Skis and an onboard helicopter is no longer enough to keep up with the Joneses -- it's become an aquatic race to the bottom.

The cost of owning a submersible varies depending on how many crew members it can carry and how deep it can go. With prices starting at about $1 million for subs with the shallowest depth rating, costs can reach upwards of $4 million for the larger, deeper-diving vehicles.
