Interested in truly exploring the underwater world without the nagging need for an air supply?  Introducing the world’s first recreational and somewhat cheap re-breather.  Most scrubbers are upwards of $12,000 – but the folks at Poseidon Discovery have… well …..discovered how to make a rebreather far more cheaply.  It even has automatic and continuous safety checks which are updated on the on board computer (with display of course).  And just in case, there is a built in conventional SCUBA setup.  $6,000 BUY
